View Camelbak Omega Reservoir 3L US. It is durable, virtually taste free, and easy to use, ideal for long days out. Used by the military, the camelbak has a lifetime.
I started using my camelbak blowfish hydration pak while doing voluntary trail maintenance out at paint creek.
The reservoir's proven durability, omega® wide mouth opening, rugged materials ensures the reliable delivery also includes big bite™ valve and hydroguard™ technology. I picked up camelbak's 3 liter reservoir hoping to save some weight over nalgene bottles and to hydrate on the go. I used camelbaks while on multiple deployments so when it came time to purchase reservoirs for my sons in preparation for a 3 day hike along the appalachian trail i turned. And this 3l crux works just fine.
