Under Armour Women's Base 4.0 1/2 Zip

UA Base 4.0 Extreme Baselayer is our warmest yet, locking in your body's heat to deliver extreme warmth in the extreme cold. Built for lower activity, it uses a unique pattern that's designed to trap heat without adding bulk. A soft, brushed grid interior traps air against your skin to closely manage your body's microclimate, while the material wicks sweat and dries really fast. 4-way stretch construction moves better in every direction, and the generous 1/2 zip front with raglan sleeves makes for easy layering. UA Scent Control Technology helps keep you undetected in all pursuits.
