Weighing less than half a pound but still equipped with a comfortable, well-fitting suspension system, the Osprey Katari 1.5 hydration pack is perfect for cycling adventures that call for water, a bounce-free ride, and not much else. The pack's suspension uses a foam framesheet and ridged mesh-covered ventilating backpanel. The harness uses mesh to provide breathability while the rolled, soft-edged straps provide comfort and stability. A removeable 20mm webbing hip belt helps keep the pack stable on your back. A 1.5L Hydraulics reservoir is tucked neatly inside the panel loading pack and a magnetic bite valve attachment on the sternum strap keeps the hose secured. An external zippered scratch-free, heat-embossed slash pocket is perfect for a phone or sunglasses. A blinker light attachment point (light not included) lets you equip the pack for low-light visibility. The Osprey Katari 1.5 hydration pack is available in your choice of colors.
