Shimano Unzen Hydration Pack
Beneath its deceptively peaceful surface, Mt. Unzen in southern Japan hides the awesome explosive power of a volcano. It was the hidden primal force of this mountain that inspired Shimano to create the UNZEN hydration pack collection. With no excess straps or bulk to hold you back, UNZEN bags are specifically designed to power an aggressive off-road riding style. After installing your hydration system, just throw in your tools and favorite energy bar. Fasten the Rider Fit X-Harness. And head for the hills.
Just recieved my Shimano Unzen 15, this pack is awesome! Very lightweight, plenty of storage, and super comfortable! I love the rider fit x harness system, my arms now have a full range of motion and the pack stays put.
