Sized to fit kids ages five and up, the Camelbak Skeeter Hydration Pack features a compact design and an internal 35-oz. OMEGA Reservoir. Camelbak recently refined their entire OMEGA Reservoirs with a HydroTanium polyurethane film that further enhances the integrity of one of the most burst-resistant hydration reservoirs in the industry. The Skeeter Hydration Pack doesn't have a clutter of pockets, but it does have plenty of reflective elements to increase rider visibility in low light conditions.
