This year our Rainfoil jackets feature a 100% recycled polyester shell along with 2-layer seam sealed protection and lots of large pockets to keep you & your essentials protected from the elements. The WeatherEdge® Plus waterproof/breathable membrane helps you stay cool and dry in wet conditions, and a vent in the back sheds excess heat during rainy day adventures. The adjustable hood and hem seal out moisture and trap heat during colder weather.
