The Under Armour Base 1.0 Crew is an ultra-lightweight base built for higher activity levels or less intense cold. The 4-way stretch polyester blend material allows for a full range of motion and prevents muscle fatigue. ArmourBlock anti-microbial treatments will help protect you clothes from odor-causing bacterial formation, allowing for closer shot opportunities in the field. Thermal grid fabric traps heat in tiny pockets for long-lasting protection. Raglan sleeves and flatlock seams unlock mobility and eliminate chafing. Thumbholes keep sleeves secure and help seal in more body heat.
