The Crux hydration system is a water reservoir used in a backpack to create a hands free hydration experience. It is at the core of every backpack we make. Crux was designed to optimize how water is carried and consumed for users in the most extreme areas of performance. These include war fighters, astronauts, ultra marathoners, mountain bikers, and everyday adventurers. The new Crux hydration system is designed to allow people to take their performance to new levels. Providing 20% more water per sip along with intuitive ergonomics, improved loading, and full-proof leak protection, the Crux line takes the industry leading hydration system beyond our users expectations, so they can say out longer and go further.
