Hydro 3 has been designed specifically as an active riding pack with Kriega's 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 underarm 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 waistpacks to be also worn. Hydro 3 can be worn with or without a waiststrap - we recommend to use a waiststrap for maximum stability, when carrying the full 3 litre (100 oz) water capacity.
