Fossil Outdoor Inc. BōnDry - Hydration Pack Bladder Dryer, Made in The U.S.A, Patent Pending, Original Hydration Bladder Dryer. USDA Certified Biobased Product

I have been using them for over a year to dry out my trail running water bladder. Dries it out perfectly. Bought a second pack and use them to dry out my water bottles. Solid product, great value!

I had to modify mine to fit my Camelback reservoir (it has a rib running down the center, so I followed the instructions and carefully cut a slot). I wipe out my reservoir with a paper towel and then leave the BonDry in for a few hours to complete the wicking of the residual moisture. Effective!

Has worked great the 2 times I’ve used this. Drys out my bladder great.

This product works great. No more worries about making sure bladder is dry to prevent icky stuff from forming. Just put it in, after you empty bladder of course, and walk away. Its that simple. I do move it around a little to suck up the remaining water in the bottom. Your bladder will be ready when you are!

I was skeptical that this would work. I didnt really understand how it possibly could be that effective. But I gave it a try, and by golly - it works like a charm! My hydration bladder is completely dry after just a few hours with this thing in it. Even the hose! Other solutions just didnt work well for me, but this! This is the answer.

If you have a hydration bladder this is a must have. It works great to dry the bladder out and get the water in the corners that are hard to get. Very easy to use. You just insert it in the bladder and leave it out over night. The next day its dryer out the bladder.

In my experience it takes less than 24 hours to dry. Great little solution.

Works exactly as described. I use it in my Osprey/Camelback. Bone dry in hours.

I was a bit skeptical when I saw this product on my Facebook feed but after just 12 hours of use I am 100% sold how amazing it is. I put it in my Camelbak Lobo 3L bladder and over night it was almost completely dried out, a process that usually takes me a few days to accomplish normally involving using something to hold the bladder open, hanging it upside down for a few days, and blowing out with compressed air multiple times. With the BonDry I dumped the water out but the dryer in and set it down on my table, the next morning practically no water left in the bladder just a bit of run off from the hose. I have 3 different bladders I regularly use and Im so happy that after 15 years of using bladders I finally have a good way to dry them out.

Perfect to dry my hydration pack!
