The H2O backpack was born to allow you to bring everything you need, in addition to water.
For that it has a capacity of 10L and numerous internal and external pockets (including a specific for valuables).
The whole bag is made of Polyester, with soft inserts in the right places for the maximum comfort. To complete the comfort, there is the strap at the waist to better secure the backpack to the body. The included water bag has a capacity of 2L and is already equipped with a valve.
