The CamelBak Rogue Pack is designed to carry enough water for two or more hours of biking. It can also hold other necessary items, such as a bike tool, pump, wallet, spare tube, and phone. It holds up to 2 liters of water and has a comfortable Air Mesh harness. An Air Channel back panel makes the pack breathable and comfortable during an intense workout. A reflective strip improves safety, and a low profile keeps the pack from affecting your balance.
