The OMM TrailFire Vest + 2 × 350ml Flexi Flask is a stripped-down, ultra-light running vest , designed for everyday workouts, quick trail runs and shorter runs where you just want to carry the bare essentials – comfortably and securely. The vest comes complete with two 350ml flexi bottles , making it a convenient grab-and-go solution ready straight out of the box.

The TrailFire vest is ergonomically designed to carry weight across the shoulders and midsection , ensuring that your lungs are not restricted while running . The fit is close to the body and more like a garment than a backpack – stretch mesh and soft edge bands keep the contents close to the body and minimize bounce , even on technical terrain and at high heart rates.

Despite its minimalist design, the vest offers seven easy-access pockets on the front for energy, phone and small items, as well as a 3-liter mesh pocket on the back for an extra layer or gear that doesn't require immediate access. The back pocket can also be used for a hydration bladder up to 2 liters , making the TrailFire flexible enough to scale up for longer runs if needed.

For hydration at the front, the vest has space for up to two soft flasks and is supplied here with 2 × 350 ml OMM Flexi Flasks . The vest is also compatible with larger bottles (up to 500 ml) , depending on preference. With the UGR – Universal Gear Rail, the capacity can be easily expanded, for example by combining the vest with the Compressor Pod for an additional 5 liters of pack volume .
