The UltraFire Vest provides 7 easy access pockets for everything you need on a run. An additional water-resistant 5 litre roll-top back pocket allows you to carry extra dry kit on longer colder days. The UltraFire’s ergonomic design stabilises the vest at the shoulder and diaphragm allowing your lungs to be unrestricted for optimal performance. Includes two 350ml Flexi Flasks. With all the easy on the move access as the TrailFire, the UltraFire adds a 5ltr secure, expandable rolltop bag on the back allowing for proper stowing of less accessed kit.
