When traveling we always desired a well thought out enduro tank bag which was rock-solid seated yet easy to remove. Apart from that, it should be made of the most robust zippers and top quality materials. Sadly, we could not find one. That is why we founded Enduristan back in 2008 to make one ourselves. In the course of doing this we invented the Expandable Volume Technology to give you the freedom to adjust your tankbag to any desirable volume without restrictions. Today we are proud to offer you the Sandstorm 4 line which marks the latest development step of our legendary Sandstorm Tankbags.
