Full protection combined with cooling ventilation properties in a skinny design are the main benefits of this backpack. With 16l capacity this backpack carries all your stuff for an intense day of riding: 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. You need more space? No worries, the Flex_Panels let you pack even more of these yummie... And thanks to slick design using special coated, lightweight ripstop fabric it's easy to clean.
