The On Running shorts are reduced to the max. Made ultralight, they boast clever, essential details needed for your run with no wasted space. Two in one, they feature a lighter, airy outer short and a snug inner tight. At the rear of the shorts, is a moisture-sealed pocket to hold your essentials, and keep them sitting snugly and secure from bouncing around on your run. Made of the highest-quality materials, the outer of the Running Shorts is made from a four-way stretch polyamide and elastane blend that is ultralight and fast drying. Reassuring support comes from the extended inner shorts that gently hug your legs. The technical fabric of the inner tight and subtly studded inner prevent riding up – even as your pace increases.
