The Techsilk 8" Shorts are a prime example of Satisfy's dedication to boundary-pushing running gear. With a two-layer design, they're the perfect balance of comfort and performance, with an outer shell made of a super-light quick-drying fabric known as TechSilk™ and an inner lining made from Satisfy's ultra-soft Justice™ fabric. This material has been given the brand's Coldblack® treatment for a cool handle that regulates temperature when the heat is on.

What else? Those bonded seams cut down on chafing, while that double-layer waistband hides a sneaky integrated sweat-proof phone pocket. That s-clip is a useful addition too-perfect for keeping keys from going AWOL.
