Rated 2 out of 5 by from Nice pack, watch out for reservoir I own a few different Opsprey small size packs with reservoirs and love them, but this model we just got has the Hydraulics LT 2" screw-crew cap top (not the 3") and is a NIGHTMARE to clean and will NOT air dry on its own, even when propped open with the normal kitchen cooking utensil. The internal bladder sub-compartments with extremely tight interior seams/ edges where removing residual water requires swabbing with a paper towel and well-bent coat hanger, and the quick disconnect hose is impossible to void of all water. Be careful of the reservoir system you are getting or spend the extra $25 for the cleaning pack ...or get creative with PVC pipe, hangers and paper towels.
