"The Patagonia Multi Trails 8-inch Short is built for a simple training day that turns into something longer. The recycled-polyester double-knit liner handles long contact hours without friction and stays fresh across back-to-back days. The OceanCycle-certified face fabric and spandex blend move with the body so the short works as hard on a backpacking approach as it does on the opening miles. What Our Gearhead® Experts Are Saying:""The stowable back pocket snaps flat so it never catches on a pack hipbelt, which matters on any run that turns into a hike. The built-in liner handles the miles without the chafe that comes from a separate short underneath."""
