When all you want is water, Camelbak's racing red/graphite HydroBak 1.5L Hydration Pack is the ideal hydration solution for you. Built with a minimalist design for maximum mobility, the pack holds the included 1.5L Antidote reservoir and little else. Mesh straps improve ventilation while cutting weight, and the reservoir is built with a center baffle to maintain a low-profile, even when full; to prevent water from sloshing around and throw you off balance during activity.
