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

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

It works

This is a great invention. I always struggled to dry the inside of my hydration bladder. This little gadget does the trick in no time. It works amazingly well!

Works as advertised. Made well and USA made. Bought a second one as was so happy withe the first, which was a Christmas gift.

I mean, it works. But no better than a towel

I had high high hopes for this item. I have used it a few times and have never been happy with the results. Had the item inserted into a bladder for several days and there is still water that had not evaporated. Bladder now smells of mildew as does the insert. Into the garbage it goes. Don’t waste your money.

Sucks the water right out of the bottom. I was drying with paper towels and sometime a piece of towel would get left behind. If I didn’t do that there would still be water a week later. This soaks it right up. I hang it with my camel back hanger and stuff this in and bam it dries in a day. I will be putting the word out.

Man, I appreciate cool new inventions, and I want to support a small business. But after trying this a few times in 2 different brands/sizes of bladder systems, it just doesn’t really work much if at all better than just propping the bag upside down with a big plastic spatula or kitchen tings inside. Magically sucking the remaining moisture out of the tube that stays on the bag was a big draw...but it didn’t really do that. Appreciate that it’s compact, easy to insert and doesn’t look as janky as my kitchen tool method. And maybe for $8 I’d get a couple. But just can’t justify the price for the so-so performance.

I use this in my Osprey Hydraulics 1.5 LT bladder, and it is completely dry the next morning. For context, I live along the Gulf Coast, and nothing dries overnight.

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