Under Armour Iso-Chill Run Black/Reflective S Running t-shirt with short sleeves

We flattened out the fibers and added some science to create a game-changing fabric that quickly pulls heat away from the skin-keeping you calm, cool, and crushing at max capacity.

• Iso-Chill fabric helps disperse body heat, making it feel cool to the touch
• Mesh back panel for ultimate breathability
• 4-way stretch construction moves better in every direction
• Material wicks sweat & dries really fast
• Anti-odor technology prevents the growth of odor-causing microbes
• Split back design can be worn open or tied up for a slimmer, more secure fit
• Reflective details for low-light runs
