Under Armour ColdGear Fitted Mock Top We all hate it. That stiff, distracted feeling you get when you're out in the cold. That's why, Under Armour have built a baselayer that keeps you warm and dry without being bulky or riding up, so you can stay focused all season long. The Under Armour ColdGear Fitted Mock is designed to keep you warm and dry. It is crafted from a dual-layer fabric with an ultra-warm, brushed interior and a smooth, fast-drying exterior. This keeps you toasty and allows built-up moisture to escape so you stay dry. The stretch-mesh back and underarm panels provide strategic ventilation without sacrificing warmth. The 4-way stretch construction moves better in every direction allowing total freedom of movement, whilst the ergonomic design keeps seams off of high abrasion areas. The mock neck construction provides added coverage and warmth.
