The Under Armour Evo Coldgear Compression Men's Crew top traps heat and provides the ultimate in mobility and comfort. The heat is trapped by a brushback knit fabrication and a silicone gripper at the hem to keep the shirt from riding up and letting cold air in. Ultimate comfort is ensured with flatlock seams and a raglan sleeve construction. The seams are sewn flat for less bulk and chance of abrasion on the skin, and the sleeves extend in one piece to the neckline. Finally, the Under Armour Evo Coldgear Compression Men's Crew top keeps you dry and warm with a superior moisture transport system to wick away moisture.
