CamelBak Mule NV 100oz 2014
The CamelBak Mule NV is a narrow-gauge pack for 3+ hours of all-terrain action in any weather condition. A new, redesigned reservoir is much easier to close and use. Whether you're biking or hiking, the Mule NV will carry all the supplies and fluid you need to get you there.
Have had this pack for a while and I use it all the time, even on day hikes. Pros: removable hose lots of pockets flexible storage good size water reservoir ample storage Cons: reservoir cap can still be a problem to remove waist straps should pull opposite (like Osprey packs) bite valve can leak - make sure you close bite valve when carrying in car. I have leaked water all over car more than once. Overall a solid pack that is hard to beat.
