Mazama’s Sidestream hydration waistpack lets you hydrate smoothly and easily on-the-fly.
Sidestream's self-storing drink tube allows you to hydrate in-stride without slowing down. Sidestream features a fill-in-pack, 45 oz. reservoir, large bore drink tube and our original high flow DesChutes Bite Valve.
Sidestream sits in the small of your back, close to your center-of-gravity for a comfortable, no bounce fit. You stay in balance and your fluid doesn't slosh.
