Though any of the CamelBaks can be used for biking, a favorite of cyclists is the CamelBak Rogue. The CamelBak Rogue has a 2.5L liquid capacity and also comes with four additional storage pockets perfect for storing your phone, wallet, or a small first-aid pack. The Rogue also has breathable, adjustable straps so the pack can be carried on your back comfortably and easily.
