Keep it clean.

Prevent microscopic creepy-crawlies from colonizing your hydration set-up with the help of the Osprey Hydraform Reservoir Cleaning Kit. Especially important if you've filled the bladder with liquids other than water, this kit gets to every nook and cranny with brushes for both the bladder and the tube. A hanging rack is also included to allow air to circulate through the reservoir for fast drying.

Doesn't work with all hydraulics

  • Familiarity:I've put it through the wringer

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

True, the smallest size reservoir was designed after this drying rack was created. You are right about everything else working well!

Makes for easy cleaning


Keep your bladder clean!!!

  • Familiarity:I've used it several times

You have to keep you bladder clean. You can get sick, you can ruin a vacation. This tool helps do just that.

Unanswered Question

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

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?


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!

  • Familiarity:I've put it through the wringer

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.

Grunge was Great...

Grunge was Great...

...but not in your hydration bladder!

Keep it Clean!



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.


Worth it!

    Definatly a of thoses things you might not want to spend $ on, but necessary & as mentioned by previous reviewers', it works!


    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.


      big help

      • Familiarity:I've used it several times

      it is definitely necessary to keep the reservoir clean!


      Easy Cleaning

        Simply put it makes it easy to clean your Osprey Hydraform reservoir. The hose brush fits perfectly and does a great job and they hanger will finally allow the inside of you bladder to dry completely.


        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..
