UA Base 4.0

Product Information

Engineered for extreme cold conditions and periods of lower activity, the UA Base 4.0 is Under Armour's warmest baselayer. It's designed to trap your body's heat efficiently without adding unnecessary bulk, making it an ideal choice for staying comfortable in frigid temperatures. The updated fabric offers a softer, smoother feel for maximum comfort and easy layering under other gear.

This baselayer features advanced thermal grid technology with a brushed interior that actively holds warmth close to your skin, managing your body's microclimate. It quickly wicks away sweat and dries fast, ensuring you stay dry and fresh. The 4-way stretch material provides unrestricted movement, adapting to your every motion.
