If you want to move fast in the mountains there's just nothing better than a Hydration Bladder system which enables you to drink on the go. It also helps if you tend not to reach for your water bottle very often, which can result in dehydration. All our bladders are here with Bite-Valves, Easy Opening features and Quick Release tubes.
