The Camelbak Vantage 35 combines the new N.V.I.S. (pronounced "envious") back panel technology with the traditional hydration pack. The pack works best for longer day hikes, ski tours and ice climbing. If you go light, you can use it for backpacking (personally it's a bit small for me). Fully loaded, the pack rides great on the back.
The Vantage 35 comes with a 100 oz. CamelBak bladder and an insulated neoprene tube sleeve.
