Bring along all your essentials with the minimalist Shuttle 6L bike hydration pack. This 2-liter hydration pack with bite valve offers cooling comfort thanks to the breathable airmesh back panel and shoulder straps. Sunglasses stay protected in the fleece-lined pocket, quickly access your pump in the dedicated sleeve. The sternum strap offers the added bonus of a rescue whistle. The Shuttle 6L has a home for everything you need and nothing you don't. Adventures are messy. If your Dakine bag gets dirty, it's recommended hand washing it with mild soap, cold water and a soft bristle brush. If hand washing is not going to do the trick, use a front loader washing machine. To ensure your backpack doesn't get tangled, place inside a pillowcase or mesh bag before washing. Always use cold water, mild soap and run on a gentle cycle. Never bleach your pack. Hang to dry in a warm but shady place, ensuring both inside and out are dry before storing. Dimensions are 360 cubic inches (6 liters), 17 x 7 x 2'' (43 x 18 x 5cm). Material: Nylon Ripstop, Polyester.
