Product Info User Reviews

UA's longsleeve baselayer crew built to take on extreme cold, without the bulk.

WHAT'S IT DO? UA athletes don't let extreme cold slow them down. They grab our Men’s UA Base™ 3.0 Longsleeve Crew for maximum warmth and minimal bulk. The thermal grid fabric is ultra-soft and traps heat like a beast. Its ultra-comfortable fit, raglan sleeves, and flatlock seams keep you totally mobile and chafe-free. As you heat up, the signature Moisture Transport System wicks sweat away from your body to keep you warm and dry. Don't let the cold stop you. Stop the cold.
