Our TRANSOM series will blow you away – literally. This feature exclusive to ION creates airflow by shifting the backpack away from your back when you go uphill. To go down, just release the system and pull it tight. Not just bla bla, it really works! With 16l capacity, this backpack carries all your stuff for a whole day: up to 3l water reservoir, tools, pumps, tubes, additional rain jacket and jerseys for changing, protectors, bars, and loads of candy. Of course you can fix your helmet, too. Need more space? No worries, the Flex_Panels let you pack even more of those yummies… By the way: the slick design using a specially coated, lightweight ripstop fabric enables you to remove what your rear tyre left on your rucksack.
