DetailsBring the essentials with the minimalist Shuttle 6L bike hydration pack. The two-liter hydration reservoir with bite valve sits neatly in a backpack with cooling comfort thanks to the breathable mesh back panel and shoulder straps. Sunglasses stay protected in the fleece-lined pocket, and a dedicated sleeve provides easy pump access. An updated recycled poly outer is rugged and sustainable, and the sternum strap features a rescue whistle. The Shuttle 6L has a home for everything you need and nothing you don't.
