Perfect for warm-weather running, On Running's LIGHTWEIGHT SHORTS are ultralight, versatile men's shorts that are quickly forgotten.

Soft yet hard-wearing, these shorts are made from a technical blend of four-way stretch polyamide/ethylene fibers, placed on the front and inner layer to dry quickly and ensure total freedom of movement. A perforated polyester fabric on the back keeps the wearer cool.

A number of details enhance comfort and functionality during the race, such as the elastic waistband for a perfect fit, the back pocket and the key holder.
