When your hydration system needs a little polishing, Osprey's Hydraulics® Reservoir Cleaning Kit is the only answer. This kit has everything you need to clean and maintain your hydration reservoir and delivery system. Features: Reservoir cleaning brush Delivery system cleaning brush Drying rack (2L / 3L Hydraulics reservoir compatible)
This is designed for the old reservoir model that had a large circular opening (similar to Camelbak). I found it to be okay, but not great. The kit is important for the tube brush. The other brush is convenient, too. The drying rack allows it to hang while drying, but it does not open the bladder a lot to get good ventilation. So I suggest drying the inside with a towel as much as you can then hang it to finish drying.
The drying rack will not work on the new reservoirs. Hopefully Osprey will starting making one for the newer models or sell the brushes without the drying rack.
Sadly as per other reviews the drying rack that is included is clearly for the Camelback wide mouth bladder. The diagram in the instructions even shows a camelback style bladder. I had hoped that due to the age of some of the other reviews Osprey would have updated this set by now but they have not.
Not sure if I do not understand the construction of the drying plastic "rack"...? The Osprey bladders have plastic sleeves or dividers in them, which prevents the drying rack from entering the bladder and opening it up for air flow...You can only insert the rack 1/3 of the total length of bladder...does not make sense to me. Brushes etc are all OK.
Quite surprised to find the instructions to be for a Camelback reservoir and not the Hydraulics reservoir. Completely incapatible with the Hydraulics reservoir! A complete spinoff of the old Camelback drying system. What a rip off!!! Touted as an Osprey product, shame on your R&D team. Guess I'll rig my own drying system for the Raptor 14....ugh!!
The new kit has everything in it to clean out my Osprey hydraulics reservoir. I paired it up with the cleaning tablets to preserve the quality of my reservoir bag. Definitely worth buying. Works well with my husbands off brand reservoir/bladder.
