Sierra Designs Isotope Jacket - Men's

Sierra Designs Isotope Jacket is so minimal, youll get soaked by the first few showers cause you forgot you packed it. Thats exactly what Sierra Designs had in minda jacket that doesnt try to work miracles of breathability, but deploys in an instant for rain protection and packs away to nothing just as quickly. The Isotope stuffs into one of its own two zippered pockets.
