A technical polyester and elastane fabric blend allows the Under Armour 2-Pack HeatGear 6 Inch Boxer Shorts to adhere to the contours of the wearer's leg without impeding movement or comfort. A 4-way, stretch fabrication accommodates extended mobility and maintains shape. A moisture Transport System wicks moisture away from the skin and onto the fabric's external surface, whilst a HeatGear® fabric and articulated fly panel regulate the wearer's temperature and moisture output superbly, thereby promoting a cooler, drier and altogether more comfortable environment. Antimicrobial fabrics inhibit the spread of bacteria and unwanted odours, a working fly provides convenient access to the shorts' interior and flatlock seams reduce chafing and consequential irritation.
