There are few pieces in a winter wardrobe that are as hard-working as a base layer—and anyone who’s made the mistake of throwing their winter coat over their regular office-appropriate outfit on a windy winter day knows that to be true. If you’re in a cold climate that’s prone to snow, hail or even a Nor’easter or two, a good pair of fleece-lined leggings might just change your life.

“I look for a pair that’s super-comfortable, high-waisted, with a longer length,” says model and fashion blogger Kristina Zias, who relocated from the East Coast to Los Angeles. “I want something that I can lounge on the couch in all day but then be able to throw on an oversized sweater and boots and wear them out.”

There’s a misconception that fleece-lined leggings add heft to your body, but the best fleece-lined leggings provide warmth without any added bulk. In fact, they look exactly like regular activewear, but are thinly lined with soft, warm fleece for a bit of extra insulation. That means you can wear them under skirts or dresses for the office, or as a base layer underneath ski pants for a day on the mountain. Just look for words like ”fleece-lined” or “brushed interior” in the description, which means they’re specially designed to trap and lock heat.

Whether you’re hitting the slopes or heading to work, these thermal winter leggings, recommended by fashion experts and industry insiders, will keep you reliably warm.
