The Under Armour Tactical Men's UA Tac Reactor Base Layer Mock Neck Shirt was built by Under Armour to fight back against that stiff, distracted feeling you get when you're out in the cold. That's why, they built a baselayer that keeps you warm and dry without being bulky or riding up, so you can stay focused all season long.

- Fabric has soft, brushed "nodes" next-to-skin for the right warmth that breathes as you move
