Why this jacket? It's ripstop, ultra lightweight and packable. We also added a water-repellent finish and a mesh vent at the back for breathability. Loose enough to wear over a base, it packs down into its own zippered pocket when you need to shed a layer. Ready for the Weather :This lightweight woven shell has a water-repellent finish to help keep you dry on the trail and off. Side mesh panels and a back vent add extra airflow to help you stay cool. Packable Pocket :This jacket packs down into the zippered chest pocket for compact storage when not in use. [] Product Details:Locker loop.
