Hammer hydration pack!

Was driving in search of a small compact backpack for mountain biking and downhill, which adapts perfectly to the body and also thanks to the breast-waist belt does not slip!
So the color blue is a hammer, looks really leiwand! The water bladder summarizes 3l and you can also take a small snack, spare tube, etc., so much space is there in spite of the full water bladder inside. The bag is easy (leave Simple Kitchen roll pure and open so that it does not zamklebt the water hose at the connection down and blow through with compressed air) to take out and to dry finish. The right-hand compartment in the hip has in it a key to take a small plastic carabiner, the left tray is super vision for mobile phones to store.

Still, I can only recommend this backpack!
