The Best Long Johns For Women

If you're looking for extra insulation without adding the cumbersome bulk or baggage of thick outer layers to your outfit, thermal underwear is the way to go. Long johns can be stealthily donned beneath jeans, tights, and all manner of bottoms. So wrap up warm and take a look at some of the best we could find on the market today.

What to Look For

When you’re shopping for long johns, we recommend considering the fabric type, closure style, and moisture retention to find the perfect pair for you. Our favorites overall come from Thermajane. Made from versatile polyester, these flexible bottoms are super stretchy and naturally moisture-wicking, making them a great choice for active wear. Polyester doesn’t agree with all skin types, though, so if yours is on the sensitive side, we recommend the silk bottoms from Paradise Silk. Read on below to discover the rest of our favorites.

Frequently Asked Questions

Can I machine-wash my long johns?

While you might be tempted to throw your dirty long johns in with a standard underwear load, it pays to be vigilant if you want to avoid shrinkage and other damage in the wash. Most of the long johns we reviewed are machine-washable, but temperature settings will vary based on the fabric. Delicate natural fibers like silk could see better results over time if washed by hand.

Will my long johns fit under skinny jeans?

These lightweight and snugly-fitting garments are made for layering. Thanks to their elasticated, figure-hugging fabric, they will fit closely under most pants and outer layers. If you’re planning to combine them with the skinniest jeans, though, you might want to focus your search on slim options without pockets or the like.
