Does what it's supposed to.

This cleaning kit works very well. I especially like the hose brush, the drying rack and the cleaning tablets. The big brush I haven't found much use for, but I don't tend to let my packs get too funky. The hose brush works for my 3L osprey and camelbak reservoirs. The cleaning tablets work very well and I have zero qualms about the cleanliness of a reservoir after using them. The drying rack also works on both osprey and camelbak reservoirs that I've tried. All in all a great little kit!

Doesn't work with all hydraulics

Drying rack doesn't work with Osprey half-size reservoir. Rest of kit is great and a must have.

Great cleaning kit

  • Familiarity: I've used it several times

Just received this cleaning kit last week for my osprey raptor 10 hydration pack, and this kit is awesome. I wish I would have bought it when I purchased the pack a month ago. The brush lets you get into every corner of the pack and hose. The hanging rack lets the bladder fully dry after cleaning, and they also included 2 cleaning tablets with this kit. Very happy with the price and the overall performance of this cleaning kit. A must have for hydration packs.

Keep it clean yo!

This cleaning kit works wonders on hydration bladders! Super easy to use and to keep your bladder clean! I used to not be into hydration bladders until they came out with these cleaning kits. Once I found out how easy it was to clean the bladders I knew they were for me. Now we are inseparable. I use them in my packs from hiking to skiing.


Easy to use. Cleans entire bladder/hose. Just be sure to thoroughly clean/dry the bite valve, usually you can just clean with soap, rinse, and squeeze valve to release any H2O, then repeat; but it can be disassembled for additional cleaning when necessary.


get rid of the "ick" factor

    Glad this is available, always seems there is some "ick" water to get to the fresh as the straw or bottom of the reservoir didn't quite get dry & sat & turned "icky". Happy to get rid of that "ick" water as sucking to the fresh stuff getting the bag dry will eliminate that.

    The hanger is worth it alone!

      I bought this primarily for the hanging system because I was tired of fussing with the drying process. after an hour my hydraform was dry as a bone! I have plenty of brushes and the ones that come with this kit are as good as any. Definitely a must if you have the Osprey Hydraform bladder..

      I have a Platypus big zip 3L bladder, would this hanging rack fit inside it? I'm sure the brushes would be fine.

      The platypus opening is a bit different, you may be able to just close one side and have the hook stick out the partially opened top. Or you could do what I do with my bladders and just shove the entire rack inside, hook and all to fully separate the bladder, then use a hanger at the hose exit to hang the bladder while it dries.

      Unanswered Question

      Is the hose brush of the hydration bladder...

      Is the hose brush of the hydration bladder cleaning kit large enough in diameter to clean the older, wider hoses as well as the newer ones?
