Great backpack for biking or a day hike. Some wear on the bag but still in excellent condition. The reservoir included with the bag needs a deep clean. The Kitsuma 1.5-liter offers a low-profile option with no unnecessary frills for riders who require ample hydration and nothing more. The pack's included next-gen Hydraulics™ reservoir provides critical hydration while its comfortable, stable design seemingly disappears on trail, so you can focus fully on the singletrack ahead.
