Water, sand and remote destinations. It's all part of the surfing life and exactly what the Cyclone Hydroseal Collection was designed for. The Cyclone Hydroseal 36L Backpack is Dakine's ultimate surf pack. Think bomber waterproof design sized for everyday missions and adventure travel use alike. The welded build and waterproof zippers keep dry gear dry or can be used to isolate wet clothes. An integrated board carry system frees up your hands, and exterior pockets add organization and quick-access utility.
