The lightweight VERT 6 is the second smallest pack in the DYNAFIT line with its 6-liter volume. Stretch materials allow the pack to fit snugly to your body and adapt to your size and running style. The VERT 6 is a small miracle among packs when it comes to space – it features two front pockets, each of which hold a 250 ml bottle. An integrated waterproof inner pocket keeps your smartphone protected in any weather, and two mesh side pockets can hold energy gels or other small items. An extra feature is a whistle, which is often part of mandatory gear for races. The main compartment has enough room for a jacket and will accommodate a bladder. Your poles can be attached to the back of the pack via bungee attachment points.
