OMM UltraFire 5 Vest Pack with 2 x 350ml Flexi Flasks

Jump to: Our Verdict / Features / Specifications

A lightweight running vest, ideally suited to everyday training and shorter races.

OMM says

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.

Our Verdict

7 pockets are located on the chest straps, including one zipped pocket, all of the pockets easily fit a mobile phone, so you have plenty of space, for nutrition, map, compass, etc. The back “dump pocket”, a 5-litre roll-top waterproof back pocket, allows you to carry an extra dry kit on longer, colder days.

A small integrated whistle can be found in one of the chest straps, which is incredibly handy, but also a mandatory kit list on most runs.

Very light and very breathable, the vest won’t rub or irritate you, even after extended use
