Giant's Cascade 2 Hydration Pack has room to spare for a full day of trail exploration and bike-powered adventure. With a 3 liter/100-ounce hydration reservoir in the insulated sleeve you can ride all the way to the trail's end. And, with 6 liters of cargo space you can carry the gear, clothing, and nutrition you need. Lightweight, water-resistant fabric protects your gear, while quick access external pockets, and a removable front pocket keep your gear organized. Contoured mesh back panels and high ventilation mesh shoulder straps prevent you from overheating.
