    Details

    Bulk-free warmth for the coldest days.

    When it's bitingly cold outside, layer up with the Under Armour Women's Base 4.0 Crew. Made with thermal grid fleece, this low-bulk top provides huge warmth without weighing you down. Anti-odor technology fends off funky odors, and flatlocked seams provide a comfortable fit. The fitted design keeps it tight enough pull moisture away from your body, but loose enough that you don't get the uncomfortable squeeze of a compressive layer. Built-in thumbholes keep the sleeves from bunching when you layer over this top.

    • Heavyweight baselayer for skiing or snowboarding
    • Thermal grid fabric traps body heat for increased warmth
    • Lightweight stretch material wicks moisture and maintains shape
    • Antimicrobial finish combats odors during active wear
    • Raglan sleeves and flatlock seams reduce chaffing
    • Thumbholes secure sleeves when worn under multiple layers
    • Form-fitting to reduce bulk and allow easier layering
    • Item #UND00Z4

    Warm

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: large
    • Height: 5'5"
    • Weight: 130lbs

    Just what I wanted. I'm always cold and this keeps me warm. I use it as a base layer skiing. Glad I made the purchase. Love the long sleeves with thumb holes.

    Best ever

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

    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, cozy and warm!

      Worlds worst thing is when your girlfriend has to take a break on a powered day because she's cold. This under armor gear was a game changer for her and me. I got these for her and we rode the whole day. She loved how long the shirt is so it stayed ticked in and how breathable, comfortable, and most importantly warm the base layer left her! Excellent purchase and would recommend it to anyone who tends to get cold easily.

      Nice top, would be very warm

      • Familiarity: I returned this product before using it
      • Fit: True to size

      I ordered this to wear on a Yellowstone cross-country ski outing. I'm returning it because it was heavier than I wanted. More details in the description would have been helpful - the box this top comes in says it is for "Coldest Conditions, Low Activity" . As far as fit, the sleeves and body are nice and long. it is close fitting which you want in a base layer. It is a thick material, very different from the Patagonia Thermal Weight Capilene which I decided to keep.

      Comfortable

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: small
      • Height: 5'3"
      • Weight: 120lbs

      I have bought the 1.0, 3.0 and now the 4.0. I put this on as my first layer and basically my only layer because it keeps me so warm. It is very soft. It is true to size and is stretchy so you can move without feeling like your shirt is twisting different ways like some of my other shirts do.

      Very warm

        This shirt is very warm and makes a great mid layer for skiing on cold days. The weight is pretty similar to a Patagonia R1 fleece and it's a pretty athletic cut. Room for a base layer or t shirt underneath without being too bulky to layer on top of this. My wife got this since she likes the coldgear compression shirts for skiing on warmer days and really likes the added warmth that this shirt brings
