The Duo short has amassed a loyal following since introduced over a decade ago. Though we've made refinements, the core of the Duo remains the same: a form fit mixture of spandex through the seat and inner legs and lightweight Merino wool throughout the remainder of the short for natural breathability and temperature regulation. Comfort. Durability. Inseam: S=8.75'', M=9.25'', L=9.75'', XL=10.25''. Available now for a limited time. (Just kidding. Ride all you want.).
