About this style

These thermal leggings from Under Armour are up for the challenge of cold weather winter workouts at the gym or during your run. They're cut to a slim compression fit with a mid-rise waist and encased elastic waistband for a secure, stay-put tight fit. The ColdGear® dual-layer fabric combines an ultra-warm, brushed interior that helps insulate with a smooth, quick-drying exterior that wicks away sweat during sport activities. Subtle branding on the leg adds a signature touch.

    Warm without overheating

    I bought these for my first 10K road race in Upstate NY in early March. The weather was high 30’s. The fit felt really good, soft and warm on the inside without making me feel like I was overheating. I wish it came in more colors!

    Great shape

    Yes, I recommend this

    Lovely shape and fit and not tight around waist. The material is soft, but gives good shape.

    Ripped after 2 wears

    I have the blue one so I got the black one since I really loved the fit. Within 2 wears of the black leggings, it ripped along the waist band. Truly disappointing

    Hi there! Thanks for sharing your feedback with us. We’re really sorry to hear that your black leggings ripped after just a couple of wears -- that’s definitely not the durability we aim for, especially when you loved the fit of your first pair. We’d love to help make this right. Please keep an eye out for an email from us soon!

    I have bought 3 pairs of these leggings. They feel awesome on and do not ride up on ankles. Gift is true to size but especially love the wide waistband! My new favourite leggings. Very well made too.

    Oops. I left my review for this item on the heated gear. Well here we go… my girlfriend wore it on the coldest day of the year without any discomfort. After multiple uses and washes, the item holds up very well. I plan to buy for more her. To be fair, this is my review for the heat gear to be used for indoor cycling. The item moves with your body but does not need to keep being adjusted. No sogginess after an intense workout.

    I like the leggings. Good for running in the winter. They have a little thicker lining than other leggings i have purchased. I also like the navy blue. I have washed 3 times no fading.

    These leggings are awesome! As a self-proclaimed legging snob, I am not easily impressed. These impressed me. They're perfect for layering or wearing alone, cozy and a nice material. Super brownie points for having a tall girl friendly option, which can be super hard to come by. These are definitely true to size with a little wiggle room. Now we just need more colors, preferably earth tones, nudes, caramel, browns, only taking one star away because I wish there was a higher cotton content in lieu of so much polyester, and were a tad less pricey

    Too hard to put on.

    I bought these for 4 other people. Decided to get myself a pair. Saw comment that they ran small. Went up a size. Still very difficult to get on. When I did, they didn't seem that much warmer. So disappointing. Gave them to my granddaughter.

    waist36 hips 41 inseam 28 height 5 foot 7 inches weight 190 size purchased xl im a snowboard instructor so im out in the cold a lot. Even though im broke i threw the money into these leggings and holy cow they are the most comfortable warm thick leggings i have ever put on. the warmth of sweatpants with the thinness shape and feel of leggings they are lined with thin insulating fuzziness and are stretchy but fit me perfectly. i dont feel strangled or feel like theyre slipping off of me in summary a must buy.
