Stay warm during your outdoor winter workout or walk with these comfortable pairs of thermal leggings, from fleece-lined to Merino wool.

Thermal leggings for cold weather

There’s nothing better than a toasty pair of leggings to make frigid—but fun!—winter activities more tolerable. From skiing and snowboarding to sledding and outdoor running, this one piece of clothing ensures that the lower half of your body is as protected as possible from the cold temperatures. While any old pair of leggings might suffice underneath heavier snow gear, a solid pair of thermal leggings may be all you need to go up against cold weather.

The benefits of thermal leggings

Unlike normal workout leggings, thermal leggings are designed to keep you warm while you exercise in cold temperatures, pulling the sweat away from your skin so you stay dry, explains dietitian and nutritionist Roger E. Adams, certified personal trainer and founder of eatrightfitness.com. “Most thermal leggings are made from a combination of both natural and synthetic materials, such as wool, cotton, and nylon,” he says. “The tight compression these garments give you also provide support to tired muscles and may reduce overall fatigue during a workout and provide support during the day,” he adds.

In addition to keeping you warm on a cold day, Ronnie Lubischer, certified strength and conditioning specialist and owner of Lubischer’s Burn and Blast Training, has found thermal leggings to be particularly useful for lifting weights. (These are the best workout leggings, according to trainers.)

“I have my athletes wear thermal leggings during intense heavy lift days because they help increase blood flow to large muscles in the glutes, thighs, and calves which, in turn, will maximize their lifts,” Lubischer says. He adds, “Another added benefit is that the anatomically correct stitching helps reinforce or bolster existing connective tissue (joints and ligaments), which provides added protection during lifts.”

How to choose the right pair of thermal leggings

Selecting the right material is key. Although fleece leggings might keep you warm, you may want to skip them if you’re looking for a pair for exercise, Adams suggests. This is because they can trap sweat on your skin, Adams notes.

He also points out the importance of selecting thermal leggings that fit nice and tight so as to provide support and compression. This, he says, can actually give your workout a boost as it supports your tired muscles and may delay fatigue. (Thinking about exercising indoors too?

“However, you don’t typically want a really heavy material as it may feel too heavy if you are running outside,” says Adams. “If you are cross-training or doing other types of activity, a heavier legging may suffice, but if you are running or cycling, a thinner material is likely going to feel better and a bit more natural, and still provide warmth and support,” he explains.
