The VERT 3 is an extremely light pack for trail running. With a volume of 3 liters, it is the smallest Trail Running pack in the DYNAFIT line. Stretch materials allow the pack to fit snugly to your body and adapt to your size and running style. The VERT 3 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 or water reservoir. Your poles can be attached to the back via bungee attachment points.
