The Running Bag 333 is the benchmark ultra-trail pack from WISE. Its patented 17°-angled flask pockets reduce the sensation of bouncing by a factor of four by increasing the contact surface between pocket and flask. The SpineTech™ structure, co-developed with Italian manufacturer Taiana, combines vertical rigidity with horizontal elasticity to stabilise the load while allowing unrestricted chest expansion. Every detail has been engineered to reduce mental friction during a race: intuitive access, logical organisation, absolute stability.
