You know the weather won't always be on your side when you're on a trail run, so wear the Patagonia Men's Wind Shield Hybrid Jacket to prepare you for anything. The polyester softshell fabric is ultra breathable to keep you comfy as you run while the DWR coating repels any moisture from the crazy weather throws your way. To protect you from wind and colder air, the recycled polyester and spandex panels regulate your temperature while the fold over cuffs and thumbholes keep your hands warm. This means that your sleeves stay in place when you pump for the next ridgeline, so you never have to slow down. And when you need to store your gels or phone, the zippered chest pocket is within easy reach.
