Phantom 25


Designed for OMM purists and ultralight racers who pack light and compact.

The ultimate VestPack for adventures & racing. Stabilised around your spine our unique 7 point harness connects the pack with the runner’s spine via a top yoke harness to provide the most stable carry possible. The yoke harness also frees the shoulders allowing a more energy efficient running action. Dual V-shaped anchors hug the waist to provide a secure fit and control bounce & swing when on uneven ground.

Size & Fitting Guide

If you have any questions about finding the right OMM product for your requirements please get in touch with us via and we’ll be happy to offer extra advice.

Stabilised around your spine

Stabilised around your spine the Phantom Suspension® system utilises a narrow yoke behind the neck to attach the pack to the spine rather than the shoulders allowing the shoulders to move freely increasing the efficiency of your action.

Shock absorbing suspension stabilisers

Two shock absorbing suspension cords over the shoulder work in tandem to further reduce swing keeping the pack in line with the spine.

Fitting: The pack load should be taken by the neck Yoke. The shock absorbing suspension cords can be adjusted on the move to the median stretched position.

Vertical stability

Vertical movement is reduced by two equalised anchor points fed to a shared adjuster. This creates a very stable Y-shape that hugs the vest pack into the lower spine. When the runner pushes off the weight pulls on the lower strap, as the runner drops back down, the upper strap tightens preventing the shoulder loosening.

Integrate your tent to lose weight

Every gram of your pack weight equates to minutes of time on your race. To minimise the weight weíve designed the Phantom 25 to integrate a tent into the pack. The tent poles can replace the Carbon Fibre back frame, the tent pegs can replace the back length adjustment pin and the duo mat back pad is used as sleeping mat.

Front storage options

The Phantom 25 brings the large storage of the Classic OMM packs and combines them with the high performance features of the Phantom series. A large bucket pocket on the back of the pack provides storage for waterproofs and other layers whilst two big side pockets can be reached for bottles and other items.
