The Ultrabag PRO 5L is an ultralight (195 g in S.M) and very stable (custom fit) hydration backpack with 7 pockets directly accessible.

The entire R&D team worked together with the WAA athletes to develop the lightest backpack of its category which will perfectly fit for women and men, could be beginners or experimented trail runners!

The new Custom Fit system allow a totally personalized fitting system for an unequaled comfort and an intact freedom of movement!

A lot of trail runners using classic backpacks are compelled to remove their bags to access their pockets, with all the inconvenient it has, including a big loss of time… The Ultrabag PRO 5L is accessible at 80% without removing it, thanks to the pockets optimally disposed for an easy, fast and safe access.
