Special Edition hydration pack including Hands-free drink tube used by World Extreme Enduro Champion, Graham Jarvis.

The G-FORCE JARVIS HYDRO  provides tough, long lasting performance essential for the rough and tumble world of off-road riding.

Incorporating Kriega’s Quadloc-lite™ system, the harness is angled away from the underarms giving total freedom of movement.

An optional waist strap is included for the extra demands of riding off-road.


The G-Force Jarvis Hydro has been designed specifically as an active riding pack with our unique Quadloc harness system. Providing a level of fit and comfort unequalled by any other hydration system. With a fully adjustable back-length and unrestricted under arm movement. Once set, the pack is exceptionally convenient to use, with none of the harness strap re-adjustment necessary on conventional harness systems.
The adjustable back also allows the pack position to be moved up to allow large waist packs to be also worn. G-Force Jarvis Hydro can be worn with or without a waist strap - we recommend to use a waist strap for maximum stability, when carrying the full 3 litre (100 oz) water capacity.
