The USWE Moto Hydro 8L enduro hydration backpack is geared up with a main storage compartment for your tools, extra gear, and hydration. You can also carry and extra jacket or equipment on the two external attachment straps. The shoulder straps and back panel are well ventilated, to improve the airflow and reduce weight. Keep your phone safe in the water-resistant phone pocket because we all get wetter than we plan when we ride.
