Osprey's new Hydraulics™ 250ml Soft Flasks are an ideal solution for keeping hydrated whilst out and about. Exceptionally lightweight, they pack down to almost nothing when empty and fit comfortably inside your pack's stretch mesh pockets. The combined sports cap is ideal for fast handheld hydration, whereas the included extension hose is ideal for those using the flasks in your pack's harness pocket. Hydraulics™ 500ml is also the perfect partner for the Duro running range, allowing easy hydration during high-intensity activities.
