In that case the Camelback Repack LR 4 is the ideal solution! The Repack LR 4 is a hip pack with a 1.5 liter drinking reservoir. Because the hip pack is ergonomically attached around your waist, it lowers your center of gravity. It also prevenst a sweaty back and your shoulders and back are not put under extra strain. As is the case with a backpack. CRUX Drinking System The CRUX drinking reservoir holds 1.5 liters and has a high flow rate, so you'll be rehydrated in no time. The magnetic strap makes it easy to attach the drinking tube to the hip pack without losing time or speed. The CRUX reservoir has a large opening, making it easy to fill and clean. The CRUX Drinking System included with the bag does not have a QuickLink system. This means that the drink hose cannot be easily disconnected from the reservoir. Various storage options The Repack LR 4 has four storage compartments on the outside and additional compartments on the inside to keep all on-the-go essentials organized and secure. There is also a separate storage compartment for the drink reservoir. The front of the Repack LR 4 folds open completely, for easy reach.
