The Under Armour Men's ColdGear Base 4.0 Crew is the warmest base layer designed to keep you comfortable in the coldest conditions. Crafted from a blend of 78% polyester and 22% elasterell, this heavyweight base layer features a soft, brushed micro-grid interior that traps warm air against your skin to maintain an optimal microclimate. Its 4-way stretch construction ensures excellent mobility without restricting movement, making it perfect for low-activity outdoor pursuits such as hunting or ice fishing. The fabric wicks away sweat and dries rapidly to keep you dry and comfortable throughout your activities. Additionally, UA Scent Control Technology helps minimize human odors to keep you undetected in nature. This crew neck, collarless shirt has a fitted design that sits close to the body without squeezing, providing both warmth and flexibility. Machine washable for easy care, this base layer is a reliable choice for activewear during winter months.
