The Patagonia Nine Trails Shorts are versatile, fully featured, tough yet breathable running shorts are made from a lightweight blend of 75 denier 91% all recycled polyester9% spandex fabric with 4 way stretch and a DWR durable water repellent finish. To help vent excess heat and eliminate chafing, the crotch gusset and side panels use quick drying, 100% polyester 50% recycled Air Flow mesh fabric. The built in liner is soft, breathable and moisture wicking, thanks to a polyester crepe mesh fabric with Polygiene permanent odor control. All three pockets two front, one back right side now close with zippers, and a flat knit drawcord at the waist fine tunes the fit. Inseam is 8. With reflective heat transfer logo on front and back.
