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

Given as a gift to a new hiker.

Works good and keeps bladders cleaner. Simple to use. Only thing I have come across is they are a little short for 2.5+liter bladders. Probably work great for standard 2 liter bladders.

The product works as described. It dries out inside of bladder fast. I would recommend the manufacturer make it pre spit for bladders with a baffle. It does however have stitching in place for user to do it and it appears it will not fall apart. Been using it for 2 months twice a week. Happy with purchase.

The insert is not as sturdy as I thought it would be. folds and deforms after one use, but still seems to be doing the job on absorbing the moisture.

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!

Absolutely the best invention for your hydration packs. They are everything they say and I dont know how I lived without them

Works great, what else do you need to know.

We use these for removing extra moisture out of our camel packs.

Awesome product, I have bought several for myself and my friends

I purchased this a while ago after debating on it because of the price. I have used it several times and it works beautifully! My bladders are completely dry with no leftover pockets of water. So much easier than the hanging dryers. I will probably be purchasing another one soon. I hope they come out with one that fits into platapus bladders small opening.
