The Under Armour Base 1.0 Crew Shirt is an ultra-lightweight base layer built for higher activity levels or less intense cold. Made from a blend of polyester and elastane, this shirt is supremely flexible and lightweight. Thanks to Under Armour’s signature ColdGear technology, this garment also retains heat to keep you warm in the coldest temperatures. The brushed negative grid interior traps heat, providing a superior level of warmth, and the Moisture Transport System wicks away sweat from the body. ArmourBlock technology helps prevents the growth of odor-causing bacteria. With ultra-comfortable raglan sleeves and a low-profile design, this is the ultimate lightweight base layer.
