    Heavyweight warmth.

    Don't be fooled by the heavyweight Mega-grid thermal fleece, because the Under Armour Women's Base 4.0 Leggings are surprisingly light for the amount warmth they hold. This insulating tight delivers four-way stretch for unhindered mobility, quick-drying comfort, and odor-resistant convenience. The wide waist band sits below the hips and resists binding or bunching. So, charge down the mountainside with these thermals under your ski pants when the snow is stacked, and then take 'em to the hiking trails when the melt comes, because you're going to need those quad muscles come next season.

    • A versatile baselayer for hiking or skiing
    • Lightweight and ultra-warm fabric
    • Grid technology wicks away moisture and dries quickly
    • Wide waist band assures comfort
    • Item #UND00Z5

    Warm, Flexible, and Comfy!

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: Medium

    I love to snowboard, but I hate to be cold. I was looking for the warmest, most comfortable (yoga pant flexibility) base layer that I could find, and I definitely found it with these pants. I went a size up with the intention that I would have these for many years (grow with me). With that said, the waist band is a bit loose, which is not necessarily a bad thing. Very happy with my purchase and look forward to many seasons of use!

    Best comfy top

    • Familiarity: I've used it several times
    • Fit: True to size

    I wore this to a freezing football game. But I was toasty warm and enjoyed every second 10 times more than I ever would have otherwise. Must buy. Comfy and warm.

    Best ever

    Great for the cold

      Got these for my girlfriend whose always cold and to go with the matching top. She loves them and even on the coldest days hasn't yet been cold in these layers. They're thick material she likes and was surprised at how flexible they were and still how breathable the fabric was. She wants more pairs so she doesn't have to do laundry every time we ski, would highly recommend to those who run cold or for those braving the mountains on the coldest of days!

      Thick and Cozy

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: medium

      These were definitely thicker than I was anticipating, given the last few pairs of UA leggings I've had, but they have been a crucial part of my backcountry kit for both skiing and winter camping.

      The waffle-pattern is similar to a Patagonia R1 situation, and is really comfortable for long-term wear. They do get a bit stinky after a week or so, given the whole synthetic fabric thing, but have bounced back well in terms of both stretch and scent.

      I'm pretty true to a medium in everything--5'6" 140#, 29" waist, and the medium fit well in these, too.

      Perfect for single digit days

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: Medium

      These are so warm! Ive worn them a few times up in the mountains underneath a shell when its been in the single digits. I did get a tiny bit chilly on the lift but when you're riding down and moving they are perfect. Ive been searching for more of a running tight/yoga pant fit and these are just like that! I did end up getting a medium, which fits kinda loose (probably should have exchanged for a small) The best thing about this pants is that I don't think about my legs when I have them on. Most comfy ever ever

      So warm!

      • Familiarity: I've used it several times
      • Fit: Runs small
      • Size Bought: Large

      I've been skiing in these three times so far this winter and not once have my legs been cold, even while sitting on the lift! The only thing is that when you take them off you'll have a goofy waffle pattern on your legs but hey, it's a small price to pay for warmth!

      The only downside is if you have a round booty like I do, they ride a little low in the back. But the warmth makes up for it!

      Bought these for my sister

      • Familiarity: I gave it as a gift but have feedback to share
      • Fit: True to size
      • Size Bought: Small

      I bought these for my sister. She absolutely loves them! She says they are comfy and extra warm. They are thick, but also very light. Perfect for a cold day on the slopes.
