For when it's hot. HeatGear® technology wicks perspiration off your skin, rather than absorbing it. It's engineered with UA's Moisture Transport System to deliver core temperature regulation and maximum breathability.
Fabric transfers moisture from the skin to the fabric's surface for quick evaporation, keeping you dry and comfortable.
Anti-microbial treatments provide permanent odor protection by inhibiting the growth of bacteria and mildew in the fabric.
Fabric is treated to block UV (ultraviolet) radiation from the sun, helping to prevent sunburn.
Mesh or breathable fabric inserts in high heat zones allow sweat to evaporate and cool air to circulate.
Seams are sewn flat to the garment to enhance durability and prevent skin chafing/irritation.
