The key to getting through the cold months is simple: layering. If you plan on leaving the house at any point, you’ll want the best thermal underwear for women that you can find — ones that keep you warm and don’t make you feel like you’re wrapped in wads of gauze whenever you put pants on over them.
This is especially true if you're someone who gets cold easily. One of the biggest factors to consider is how warm you need them to be. If you live in a climate that frequently goes below freezing, you'll need thick, high-quality insulation that'll really keep you warm. By contrast, if you live in a warmer zone where winters are more moderate, you may be able to get away with a thinner layer underneath — just enough to add a little extra lining.
You should also consider whether or not you’ll be taking any of your outer layers off. If your goal is to bundle up like a giant, warm-and-cozy marshmallow with no plans of removing outer layers until you get back home, you may not be as concerned with style, color, or neckline. However, if you're someone who gets hot frequently and often ends up taking layers off throughout the day, you'll probably want a pair that looks a bit less like actual underwear. Whatever style you’re seeking, these seven thermals will keep you warm and cozy all winter long.
1Heavyweight Insulation With A Waffle-Knit Pattern
This waffle-patterned, cotton-polyester thermal underwear set from Noble Mount is designed for extreme cold. The heavyweight, top-rated insulation and a full-cut neck on top keep you warm, and the lace accents add a cute touch. The elastic cuffs customize the fit, the material blend makes it dry quickly, and as a bonus, it's machine-washable. It comes in four colors including purple, pink, light blue and champagne.
2A Warm Plus Size Set That Won't Make You Overheat
This fantastically comfortable, moisture-wicking thermal underwear set features a cozy fleece lining and is completely machine-washable. The lightweight material feels awesome to wear, and it delivers superior warmth in extra cold climates. It has a special moisture-management technology that lifts sweat to keep you dry if you get overheated throughout the day.
3Fleece-Lined Fabric That's Comfy & Warm
With a mega-breathable fleece lining, this thermal underwear set is created from peached-finished fabric — a process where abrasive bristles are used to scrub the fabric and break up the micro-fibers, resulting in material that is comfortable and irresistibly soft. The cotton-spandex mix in the crewneck top does a superb job of regulating body temperature and the elastic waist bottoms stay in place without bunching. It also has a tag-less collar you don't have to be tucking in all the time.
4Ultra-Petite Fit With A Cute Lace Trim
Featuring a scoop neck with lace trim and a high waist, this ultra-petite thermal underwear set is a great choice if having a fashionable neckline is important to you. The flat-knit thermal fabric is made from a hybrid of cotton, polyamide, modal, and spandex that's engineered to wick moisture while adapting to the contours of your body. It is warm yet the material is thin so you won't feel too bulky and can wear it under clothes if desired.
5Extra Thin Material You Can Wear Under Clothes
This thin, three-in-one thermal underwear set is designed to be worn under clothing so you can add an extra layer of warmth without feeling bulk. However, the top and bottoms both work as thermal underwear too so you can wear around the house when you're vegging out or going to bed. They're both thick enough to wear out as long-sleeved tops or leggings and the lacy V-neck makes them stylish, too. Available in your choice of red, pink, or black.
6An Exceptionally Breathable Choice For Outdoor Activity
Made with a cozy blend of cotton and thermal polyamide polyester, this is one of the most breathable thermal underwear sets you can find. With a double-layer knit, both the top and bottom pieces provide exceptional warmth while not being too hot or or restricive. It is constructed to be able to move around in if you're involved in winter sports or other outdoor activities. The top piece has a rounded neckline and the bottoms boast a comfy, elastic waistband that's flat so it won't leave lines.
7A Plus Size Pair That's Suitable For Alaska-Style Cold
This super cute plus-sized thermal underwear set will grab you with its adorable thumbholes, and reel you in even more with its fantastic, high-quality fabric. The long-sleeved top is built with an acrylic-viscose combo that leaves the material soft, breathable, and extremely warm. It is also stretchy, fast-drying, and machine washable.
