We all hate it. That stiff, distracted feeling you get when you're out in the cold. That's why, Under Armour built a baselayer that keeps you warm and dry without being bulky or riding up, so you can stay focused all season long.

- Dual-layer fabric with an ultra-warm, brushed interior & a smooth, fast-drying exterior

- Stretch-mesh back & underarm panels provide strategic ventilation without sacrificing warmth

- 4-way stretch material moves better in every direction

- Material wicks sweat & dries really fast

- Ergonomic design keeps seams off of high abrasion areas

- Mock neck construction for added coverage & warmth

- Dropped, shaped hem
