The OMM UltraFire 5 Hydration Vest offers easy access for all your essentials on a run, all the while without hindering your performance. Featuring seven easy-access pockets, there is ample space for essential supplies, with the addition of a water-resistant five litre roll-top back pocket that allows you to carry extra dry kit on longer colder days. The UltraFire’s ergonomic design also stabilises the vest at the shoulder and diaphragm allowing your lungs to be unrestricted for optimal speed.
