Under Armour ColdGear compression shirts in a convenient set of two, featuring one solid black and one heathered charcoal grey. Designed for high-performance thermal insulation, these long-sleeve base layers utilize a dual-layer fabric that wicks moisture while circulating body heat to keep you warm during cold-weather training. Each shirt features ergonomic flatlock seams to reduce chafing, a classic crew neckline, and the signature logo at the chest and back neck. The compression fit provides a locked-in feel that supports muscle recovery and allows for easy layering under jerseys or jackets.
