Very good - Osprey Hydraulics Reservoir Fall 2015

This is excellent. its ridged frame holds the pak up nice and seems very sturdy. much more solid than the camelback that I bought this one to replace.
the only real complaint I have is it does not have an insulated eater tube. if it did I would give it 5 stars.
