Great all around day pack
Scored the 2009 on SAC for my 18 year old son and my boyfriend bought a new one to replace his old Rim Runner. First of all, you cannot go wrong with the Camelbak bladders. While our version (2009) has the older bladders, the new bladders are even more awesome. Changing hoses WAS a real task but they have fixed that. Camelbak has also improved the drying process.
As for the pack, there are several features I admire about this model. I love the internal sunglasses pocket. It is soft and really keeps those important things (glasses, cell phone) safe. The main compartment is roomy enough for several clothing items such as fleece, waterproof outer, etc. Great organizers in slim spaces on the external front pockets. The material is tough and stands up to weather and abuse.
Seriously if you are considering a solid day pack - get this one. It is also very adjustable and ours has been on every kind of frame (skinny to large)
If you have a short torso, I would recommend a woman's Camelbak instead.
