Our Testing Course of
Our crew area assessments all the girls’s base layers which can be included on this information. Whereas the Smartwool and REI base layers constructed for prolonged sizes haven’t but been area examined, we’ve got onboarded plus-size testers for the winter of 2024-2025. For our present reviews, we’ve got examined these merchandise in various measurement runs, attended plus-size attire panel shows, interviewed the plus-size base layer designers, and researched shopper impressions.
Whereas she groups up with many gear testers, Tilton places items to the grindstone between keyboard blocks. Thus far in 2024, Tilton has packed in 62 days and 216 hours of testing girls’s base layers. From January to December 2023, Tilton examined girls’s base layers throughout 68 days and 198 hours of recreation — together with blizzards, sub-zero temps, harsh wind, heavy and moist snow, loads of perspiration, and sunshine. Her outings came about within the frontcountry and backcountry together with bebopping through snowmobile. However that metric excludes day by day errands and shoveling duties.
Environmental journalist Kylie Mohr runs and skis in Montana in numerous and blustery circumstances. She wore these base layers out and in of bounds to see what most stored her heat and dry. Avid snowboarder and Utahan Julia Spadaro spends her winters on the resort and splitboarding within the backcountry, in addition to climbing within the shoulder seasons. She assessments girls’s base layers all through her adventures and delivers educated reviews on what she does and doesn’t like.
Testing Metrics
All through our area assessments and private expertise, we decide essentially the most aggressive girls’s base layers primarily based on quite a lot of metrics together with high quality, consolation, match, longevity, and worth. We take an in depth have a look at every product’s heat, breathability, wicking and drying functionality, materials, elasticity, stretch, weight, density, seams, hems, lower, hand really feel, and elegance.
We additionally think about essentially the most revolutionary, sustainable, legacy, award-winning, and fashionable designs on the shelf at present. Arms down, these girls’s base layers serve a variety of athletes, functions, and budgets.

Purchaser’s Information: The best way to Select the Greatest Ladies’s Base Layers
In our information, we concentrate on the very best choices for chilly climate and the winter season, which are sometimes long-sleeve tops and ankle-length bottoms.
Technically, girls’s base layers characteristic a spread of designs, together with tank, long-sleeve, and short-sleeve tops, in addition to ankle-length or capri pants. Some tops characteristic a hood, partial zipper, or thumb holes. Others are tailor-made with a crew collar, mock neck, or turtleneck. Whereas most against-skin layers lack pockets, we’ve seen leggings popping up with a spacious facet pocket, which is beneficial to stash a telephone, particularly post-activity while you pull off your snow pants.
Two elementary umbrellas will enable you to determine which girls’s base layers to purchase:
You’ll wish to think about how chilly the local weather is the place you play exterior. The colder the zone, the extra you’ll wish to think about a wool-based mix, higher-density material, and heavier material weight.
The second variable is how lively you’ll be when you’re carrying that attire. Throughout train, like shoveling or happening a winter run, your physique is producing warmth that may necessitate a extra breathable, much less density, low-weight prime and backside.
When you plan on being bodily lively in above-freezing however cool climate, we suggest an artificial mix. When you’ll be rounding out winter days in a below-freezing local weather, wool will be your best companion for heat. Different elements can affect the very best base layer selection together with your physique’s circulation, pores and skin sensitivity to fibers (like wool), and the layers you placed on prime.

Layering System
Your alarm goes off. Don’t snooze: It’s time to stand up and dressed for chilly climate enjoyable. Your layers will work in a tiered system:
Base Layer: Subsequent to pores and skin to wick sweat
Midlayer: Provides heat to retain physique temperature
Outer Layer: Safety from the weather, repels precipitation, blocks wind; insulated outer layers enhance heat
First, put in your underwear and socks. They higher be wool or an artificial mix — not cotton. Your heat, dry dermis will thanks. Your base layers go on subsequent.
Base Layer
Add your base layer prime, backside, or onesie. In case your bottoms are lengthy, be sure they go over your socks. Until you want your socks on the surface of your bottoms — that’s private desire. In case your bottoms are mid-shin size, like some compressive efficiency choices, regulate your socks and material, so there aren’t any overlapping, uneven factors that might rub or chafe.
Midlayer
Now, it’s time to slide in your midlayer prime and backside, relying on the day’s exercise.
Going snowboarding in bounds? Attain for a streamlined fleece that also permits a full vary of movement. Hanging out on the campsite? Pull on a cumbersome deep-pile sherpa fleece.
Your exercise will dictate what acceptable midlayers so as to add on the underside. Possibly you’ll pull on a fleece or insulated puffy pants for further heat under workwear trousers or snow bibs.
Outer Layer
Headed to the backcountry? Put on a snug insulated jacket on the best way to the trailhead then strip all the way down to your baselayer or midlayer to start out, given you’ll shortly heat up from exertion within the chilly temps. Working in a breeze on an in any other case heat afternoon? Go for a softshell with no insulation.
If we’re resort snowboarding in under freezing temps, and we run chilly, we’ll typically do that trio: an uninsulated ski shell over each a fleece and puffy jacket. Insulated jacket wearers will doubtless discover they don’t want all three.
A really perfect layering system is all about studying what works for you and what number of layers it is advisable to keep heat and dry.

Material Blends
The material blends of girls’s base layers embrace wool, artificial, or a mix of the 2. Inside these materials, there are numerous densities from light-weight to midweight or heavyweight.
Wool
We love wool. It regulates temperature very well and supplies heat when it’s damp or moist. It’s developed to be far more comfy towards the pores and skin and resists odors like a champ. The heat-to-weight ratio is excessive, packing a punch in a reasonably gentle package deal. It’s an excellent selection for low-intensity out of doors actions like ice fishing or spectating a hockey sport. Amongst our prime base layer decisions are the Smartwool Ladies’s Basic Thermal Merino Base Layer Crew and Smartwool Ladies’s Basic Thermal Merino Base Layer Backside, a 100% Merino wool assortment.
That stated, 100% merino wool tends to be much less stout than synthetics, wears holes extra shortly, and might get saggy all through use. If in case you have delicate pores and skin, even the smoothest 100% merino wool would possibly really feel a tad lower than cloud-like subsequent to the pores and skin. Wool will get heavier when it’s moist and doesn’t dry as quick as synthetics. Relying in your desire, exercise degree, and the climate circumstances, you would possibly desire a wool mix or straight artificial supplies.
Wool can value greater than its counterparts. Past merino-sourced wool, we’ve got examined base layers with wool from yaks, which was a premium thread, extraordinarily gentle, and tremendous insulating.
Artificial
An alternative choice to wool is an artificial material, which is often a mix that features polyester plus elastane or spandex for rebound, type, and long-lasting use. Some artificial materials are proprietary to a model with therapies that improve their odor-fighting skill and moisture-wicking prowess — the qualities that happen naturally in wool.
Artificial blends don’t supply as a lot heat and general temperature regulation that wool supplies. As a result of they don’t take in as a lot moisture they usually dry quick, they’re an incredible selection for high-intensity actions that produce numerous perspiration with out lengthy moments of standstill, like throughout a hunt, when a chill may set in.
These fibers can work very well for folks with delicate pores and skin, particularly for train use, and the bonus of higher sturdiness, stretch, and elasticity. Additionally, synthetics usually value lower than wool. One in every of our favourite artificial choices is the REI Co-op Light-weight Base Layer Tights Ladies’s Plus Sizes, at a whopping $40.
One disadvantage: Odor-intense days usually are not usually lined up properly by this fiber in its bare type.
Wool-Artificial Mix
Many people discover a honest stability of managing warmth and chill, sweat absorption, and protecting up odors in a design that weaves collectively each wool and artificial fibers. Including synthetics to blends can improve the power and general lifespan of wool attire.
One in every of our all-time favorites for carrying from the pores and skin observe to completely happy hour is the Le Bent Ladies’s Core Light-weight Crew Base Layer, which incorporates 5% elastane and maintains a pleasant form all through lengthy days.

Weight Class or Thermal Class: Light-weight, Midweight, Heavyweight
Once you store for ladies’s base layers, the merchandise are categorized by three weight zones, which typically discuss with how heavy or gentle the layer is and feels. The load class is influenced by the material density and thickness, which modifications the actions that the layer is appropriate with.
Right here, we listed the burden class in every product’s specs — below Thermal Class — which relies on our take a look at outcomes.
Weight class isn’t straight correlated to heat. A light-weight, pure wool prime can bounce again a ton of physique warmth. Will probably be simpler to maneuver in, much less dense, and extra breathable than a midweight or heavyweight wool design.
Whereas everybody’s circulation and preferences are completely different, right here’s a common start line for deciphering a weight class primarily based on exercise degree and out of doors temperature:
Sedentary:
25-32+ levels: Light-weight, wool
15-25 levels: Midweight, wool
Lively:
25-32+ levels: Light-weight, artificial
15-25 levels: Light-weight, wool-synthetic

Light-weight
When you’re working hardpack snow trails, snowshoeing, skate snowboarding, or doing uphill ski exercises in 30-degree temps, a light-weight base layer prime or backside ought to do the trick, so long as there’s no wind chill.
Light-weight layers dump warmth very well. These could possibly be an excellent piece for hotter spring laps on the ski resort. However sitting idle on elevate rides in chilly temps usually requires a hotter midweight base layer. One in every of our favourite light-weight synthetics is the Helly Hansen Ladies’s HH LIFA Lengthy-Sleeve Crew Base Layer and a light-weight wool mix that’s tremendous gentle and versatile is the Le Bent Ladies’s Core Light-weight Crew Base Layer.
Midweight
Not too ethereal and never too stuffy, the midweight base layer is perfect for wintry days snowboarding and using on the resort. It’s a good selection for snowmobiling, when pulling the throttle can pack windchill at excessive speeds.
That stated, for intense heat-building actions like big ski or splitboard excursions or snowshoeing, a midweight layer is likely to be an excessive amount of until the temps are colder, like 15 levels or much less.
Squarely midweight, we love the Smartwool Ladies’s Basic Thermal Merino Base Layer Crew and Smartwool Ladies’s Basic Thermal Merino Base Layer Backside as a well-rounded equipment for chilly or below-freezing temps and days on the ski resort.
Heavyweight
After we’re speaking excessive temperatures — 15 levels with windchill to properly under freezing — then your greatest wager is a heavy-set base layer, particularly for ski resort laps if you end up sedentary on the best way up.
Different extra passive out of doors actions may embrace ice fishing, crusing, searching, spectating occasions, hanging at base camp throughout a mountaineering expedition, or snowmobiling groomed trails, particularly if sightseeing stops are frequent.
We don’t at present have any cumbersome heavyweight choices in our information. A lot of our 100% wool midweight selects will be layered beneath a midlayer fleece and down jacket for tremendous chilly circumstances, and we desire that versatility. The Kari Traa Rose Half Zip Baselayer High and Kari Traa Rose Excessive Waisted Baselayer Pants really feel lean however are filled with warmth. These are our go-to on a 0-degree day on the ski resort. We don’t often like carrying these whereas we ski tour to keep away from an oven impact.
Base layer tops can have strategically positioned material beneath the underarms that’s extra breathable, whereas different sections present extra heat; (picture/Jason Hummel)
Material Density
A normal unit for measuring material density is gsm (grams per sq. meter). The upper the gsm, the denser and hotter that textile will likely be. A fluid-feeling shirt is likely to be as little as 50-100 gsm, whereas denim reaches into the 340-450 gsm vary.
Some girls’s base layers don’t weigh a lot however have a dense material or excessive gsm. Subsequently, they swing a excessive warmth-to-weight ratio, akin to the Kari Traa Rose Excessive Waisted Baselayer Pants with 240 gsm. After testing, we related that legging as midweight, due to the comparatively low density but excessive warmth punch.
Reasonably than including gsm labels to our product evaluations right here, we shared the final weight class — light-weight, midweight, and heavyweight — which is extra ubiquitously used throughout manufacturers. Our listed weight class relies on our take a look at outcomes. That stated, understanding how one can interpret the density of a base layer is a really useful gizmo.
Right here’s a broad rule of thumb for gsm:
Ultralight base layers: >150 gsm
Light-weight base layers: 150-195 gsm
Midweight base layers: 195-250 gsm
Heavyweight base layers: 250-320 gsm
You’ll wish to match your bodily exertion or circulation to the material density. When you plan to do excessive cardio exercise, select a base layer design with a decrease density.
When you plan to be extra sedentary — akin to ready in lengthy ski elevate traces throughout a blizzard, ice fishing, watching a hockey sport, or working errands — go for the next gsm. A better material density can be an excellent possibility for folk who’ve poor circulation or are likely to get chilled throughout winter actions.
Relying on the ambient temperatures and windchill, you would possibly go for a midlayer on prime of your base layers and beneath your outermost jacket; (picture/Jason Hummel)
Breathability
Along with trapping warmth, it’s essential to your base layer to breathe properly and effectively wick moisture. Freezing sweat will make you colder quicker. Typically, the lighter or much less dense a design is, the extra breathable it will likely be. Merino wool can be extra breathable than synthetics. Base layers will be made with a mix of supplies that place extra breathable textiles in high-heat zones.
After we’re speaking about engineering, we will’t overlook concerning the Icebreaker 260 ZoneKnit Lengthy Sleeve Crewe Thermal High and Icebreaker 260 ZoneKnit Thermal Leggings, which have a breathable mesh-like merino wool layer in all of the essential locations — the decrease legs, behind the knees, throughout the again and higher glutes, below the arms — so sweat can’t break the day. The Kari Traa Rose Half Zip Baselayer High makes use of a lighter density merino wool below the arms and alongside the edges, which feels extra breathable.
Normally, we discovered that the Smartwool Ladies’s Basic Thermal Merino Base Layer Crew is a heat winter layer that breathes fairly properly. It’s our prime choose for the lifeless of winter but in addition for alpine pursuits in fall and winter. The Voormi Ladies’s Baselayer Bottoms Full Size and Lengthy Sleeve Baselayer Crew additionally breathe slightly properly and repel water, preserving us dry after sweaty ascents and snowmobile rips.
If you already know you’re going to be busting it uphill on a heat day within the springtime, search for a fair lighter and extra breathable layer. One thing just like the Helly Hansen Ladies’s HH LIFA Lengthy-sleeve Crew Base Layer or REI Co-op Light-weight Base Layer Tights Ladies’s Plus Sizes and High will likely be a key a part of your layering system.
On colder days, you’ll be able to layer a stretchy midlayer on prime of a lightweight, medium, or heavy base layer; (picture/Eric Phillips)
Odor Prevention
When you’re packing minimally for multiday use, like a hut-to-hut ski, merino wool does wonders with hiding odors. Typically, artificial supplies don’t resist odor in addition to this pure fiber. Merino wool wicks sweat away out of your physique, permitting it to evaporate slightly than sink into your garments. Wool fibers take in practically twice as a lot water vapor as cotton and 30 occasions as a lot as polyester. The construction of wool binds with odors, taking part in steer clear of micro organism.
Our Favourite Base Layers With Wool-based Development:
Anti-Odor Remedy
Whereas polyester — a major thread in synthetics — isn’t naturally odor-resistant, clothes will be handled to imitate among the similar advantages as wool. Silver-based compounds and triclosan and triclocarban therapies are poisonous to odor-causing micro organism, preserving the nose-pinch at bay. Needless to say these therapies’ effectiveness may lower over time as a garment is washed.
Our Favourite Artificial Base Layers With Anti-Odor Remedy:

Solar Safety
Many base layers hidden beneath midlayers or outerwear jackets won’t ever see the sunshine of day. However others, particularly light-weight ones geared for year-round or springtime use, will. That’s the place solar safety is a pleasant added characteristic.
The REI Co-op Light-weight Base Layer Lengthy-Sleeve Crew High Ladies’s Plus Sizes boasts a UPF ranking of fifty+, as does the Le Bent Ladies’s Feathertop Ultralight Hooded Lengthy Sleeve Tee. However Le Bent’s design additionally presents a hood, so that you’re getting further safety of your ears, plus the again of the neck. The Le Bent Ladies’s Core Light-weight Crew Base Layer likewise sports activities a UV 50+ tag.
Sturdiness
Thermal layers are an funding, so it is sensible that you really want them to final. They’re additionally just one piece of a protracted checklist of drugs that’s wanted to enterprise out within the winter.
Artificial layers are sometimes extra steadfast than wool however may cause extra bother with retaining odors. Producers typically add artificial fibers to their wool attire to assist enhance the general timestamp. Wool is of course hotter and odor-fighting however tends to be extra fragile. You’ll wish to take care placing them on, in addition to the way you wash and dry them.
Arms down, essentially the most sturdy development of any of those base layers is that of the Voormi Ladies’s Baselayer Bottoms Full Size and Voormi Ladies’s Lengthy Sleeve Baselayer Crew. Within the model’s proprietary course of, in-house seamsters create their Twin Floor materials, a precision-blended wool expertise with a lean inside layer of superb micron-wool plus a portion of polyester and nylon. After a number of years of use, we don’t see holes surfacing in these layers any time quickly.
Ladies’s base layers are available a spread of inventive patterns and colours; (picture/Jason Hummel)
Consolation & Match
Most base layers supply a level of flexibility and are gentle or nonabrasive, which helps general consolation and match. However some base layers we’ve examined prior to now have had a tighter compression match for optimum athletic efficiency.
One of many tougher base layers to tug on is the Voormi Ladies’s Baselayer Bottoms Full Size and Voormi Ladies’s Lengthy Sleeve Baselayer Crew, particularly on the seams. Nevertheless, we love how powerful and sturdy this design is. The subsequent most close-fitting design in our information is the Halfdays Hallie Midweight Merino Legging, nevertheless it does supply ample stretch, even alongside the seams.
After we take a look at base layers, we’re in search of tops that present sufficient vary of movement throughout the chest and shoulders, in addition to when lunging or squatting. The seams should be easy or flat, and the gusset must be well-constructed so we don’t really feel any jabs or expertise chafing. The development may be very easy throughout the Ortovox 185 Rock’N’Wool Brief Pants and Ortovox 185 Rock’N’Wool Lengthy Sleeve.
We care concerning the silhouette, as a result of we desire arms that a minimum of cowl our wrists and torso lengths that don’t enable the decrease again to be uncovered to the weather.
Pant Size
Most base layer pants attain all the way down to your ankle however some capri types hit under the knee, close to the shin bone. We like a cropped size for straightforward layering with our socks and ski boots. The Ortovox 185 Rock’N’Wool Brief Pants attain the knee and get rid of the necessity to layer our pants over socks.
Bottoms that attain nearer to your toes are often tapered and comfortable, to allow them to be simply tucked in when needed. However there’s often sufficient pliability within the material to slip your winter socks beneath if you happen to desire.

Onesie & Drop Seat
Typically a separate prime and backside simply received’t lower it. We’re eager about these best-of-the-season powder days the place a niche in base layer protection may result in snow the place the solar doesn’t shine. Base layers with a seamless connection are a uncommon, however more and more fashionable, possibility within the base layer lineup. They’re known as onesies or one-pieces that embrace a prime and a backside sewed collectively. Assume moist fits and footie pajamas.
Main the cost is the Wild Rye Olivia Onesie base layer. Wearers are handled with head-to-toe merino wool. A hood provides coziness, and enjoyable patterns like chunky yellow florals stand out towards your pals’ all-black arsenal. A half-zip helps regulate temperature on this heat, 230 gsm fashion.

The drop seat is a detachable bottom flap, often with zippers that span hip to hip above your booty, to make utilizing the lavatory simpler. Nobody likes having to get completely bare to reply nature’s name. Brr!

Hoods are pretty uncommon on base layer tops. In spite of everything, what number of hoods do you actually wish to be carrying directly? Hoods can generally add bulk across the neck and head space, particularly in case your base layer, fleece, puffy, and shell all have one.
However a few of our favourite base layers rock a hood, just like the First Lite Kiln Hoody and the Le Bent Ladies’s Feathertop Ultralight Hooded Lengthy Sleeve Tee, which is excellent for spring mountaineering and sunny, heat ski excursions. It may be good to have a slender hood round your neck to layer below a helmet or hat, which might additional block the solar and wind.
Sure base layers have a scoop neck, whereas others have collars with a quarter- or half-zipper on the chest and décolletage.

On long-sleeve base layers, the cuff is a bit of cloth that demarcates the garment’s edge on the wrist. It’s sewn on to assist stop fraying and enhance consolation. The lengths of base layer sleeves, in addition to the depth and elasticity of their cuffs, can vastly differ. Longer sleeves can attain the knuckles, protecting the backs of the arms and palms.

The exact width and placement of the loop that goes round your thumb varies by model and design. A handful of thumbhole designs are easy elastic bands. However many thumbhole designs are created with a large piece of cloth and embrace seams.
Typically, thumbholes will be tedious to slip into, cumbersome below ski gloves, or incompatible with a watch. Some ski jacket designs have built-in wrist gaiters with thumbholes, which leads a visitors jam round your wrist — and at worst, poorer circulation — in case your base layer prime additionally has thumbholes.
We particularly just like the thumbholes on the Black Diamond Ladies’s Answer 150 Merino Baselayer Crew. They’re stretchy sufficient to be comfy whereas carrying them for back-to-back hours. The Wild Rye Olivia Onesie thumbholes embrace a beefy cuff, so that they’re cozy to put on indoors, however exterior, we pull them again to placed on gloves. We discovered the thumbholes of the Voormi Ladies’s Lengthy Sleeve Baselayer Crew to be too small and restrictive, vastly because of the lack of stretch within the seams. The First Lite Kiln Hoody thumbholes are very easy to tug on and off, as are those on the Icebreaker 260 ZoneKnit Lengthy Sleeve Crewe Thermal High.
