HeatGear Armour Short Sleeve

The Under Armour HeatGear Armour Short Sleeve is the foundation baselayer trusted by law enforcement, military personnel, and tactical operators who demand reliable moisture management under duty load. Designed as the first layer in any combat loadout, this short-sleeve baselayer wicks sweat away from skin while maintaining freedom of movement—essential when wearing armor plates, duty belts, or extended tactical gear. Whether deployed in high-heat environments, conducting field operations, or training in demanding conditions, this baselayer performs where comfort and function cannot be compromised.

HeatGear Armour fabric features advanced sweat-wicking technology that moves moisture away from the body to the outer surface, where it evaporates quickly—critical during sustained physical exertion or in hot climates where heat management directly impacts operational effectiveness. The four-way stretch construction allows unrestricted movement across all planes of motion, preventing binding under body armor or tactical vests. Lightweight at just 0.37 lbs, the garment adds minimal bulk while delivering durable, form-fitting coverage that stays in place during dynamic movement, climbing, weapon manipulation, or rapid repositioning. The fabric construction withstands repeated washing and the rigorous demands of field use without degradation.

Law enforcement patrol officers, military personnel, private security contractors, and tactical athletes benefit most from HeatGear Armour as a base layer beneath soft armor, rigid armor systems, or standard duty uniforms. The short-sleeve design accommodates shoulder holsters, armor plate carriers, and tactical vests without excess fabric bunching or creating pressure points. Sized at 3XL, this baselayer accommodates larger frames common among uniformed personnel while maintaining the same moisture-wicking and stretch properties. Compatible with any duty configuration, it performs equally well during indoor training, outdoor operations, or sustained missions where reliability under stress matters most.
