The 7 Best Thermal Underwear For Women

Amazon/Bustle

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.

HieasyFit Fleece-Lined Set (Sizes S - XXL), $20-33, Amazon

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

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
