When you need to stay warm, the Under Armour Tactical Reactor Base Mock is the very best option. This base layer is a blend of polyester and elastane combined with ColdGear reactor technology. It insulates by retaining body heat, all while working to ensure breathability. The mock neck featured on this base layer also provides additional coverage when temperatures are low. This shirt is fitted, meaning it’s not too tight but not too loose. Comfort matters, that’s why the fabric wicks sweat and dries quickly. Anti-odor technology is also built into the fabric blend to prevent the growth of odor-causing microbes. Since this shirt features a four-way stretch, it’s made to move with you instead of against you. If the goal is to be warm and comfortable, this mock neck delivers.
