When we focus on layering for warmth, it’s easy to get caught up in figuring out what great shirt and sweater you’ll pair under a topcoat. In our rush to figure out how much we can stack over clothes, it can be easy to forget about what goes underneath them.

Long underwear isn’t perhaps the sexiest phrase to describe base layers, but their benefit (keeping you warm and dry when it’s cold out by moderating your body temperature) can make all the difference on a particularly frigid day. Below, ten of our favorites for you to try.

Uniqlo Heattech Ultra Warm Long Johns

Muck like its excellent Ultra Light Down jackets, Uniqlo has made a name for itself with its quality Heattech products. The price for its long johns is easy to stomach, and if you don’t need the Ultra Warm version, they also come in Extra Warm and, uh, normal Warm.
