The Draft UA Catalyst 7” shorts fuse UA’s superior performance with advanced green technology to create one of the toughest, lightest, most comfortable running shorts you’ll ever wear. Plastic bottles are melted down and stretched into super fine fibers that are used to create our ultra-soft and durable UA Catalyst fabric. Mesh insets are added to key ventilation zones to dump excess heat—keeping you cool and comfortable. The UA Draft shorts include a built-in anti-microbial brief that eliminates odors. Add to that 360° reflectivity for lowlight safety. What you get is lightweight running gear with everything you need and not an ounce more.
