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

Works great. Dries out my Osprey bladder in a few hours. I left a small puddle of water in the bottom last time - more than youd normally leave - and had to flip the pad over to the dry end to get the rest after a couple of hours. Buying a second one for a stocking stuffer so I dont have to share

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 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.

I wasnt sure if I was just throwing money away. It actually worked. Left it overnight in the hydration bag and next day it was actually bone dry!

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.

This is pretty cool. Ive used a few times and it definitely helps absorb residual liquid from my hydration pack. (I have an Osprey 3L bladder with the fold over top)

Save your money. I put this in a platypus bladder over 3 weeks ago. Pulled the bladder out today and there are still water droplets and the product is damp. I had better results draping the bladder over a smart bottle. Of course I’m out of the return window.

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

Worked perfectly for our bladders. We ordered the pre split ones for our Camelbaks. Great quality. Probably last a lifetime time.

It is not often that game-changing backpacking gear comes along, but I think now is one of those times. If you watch hiking vids on YouTube, youve probably seen the ad for the Bondry from Fossil Outdoor (bone dry - get it??? fossil??? haha). It looked pretty gimmicky to me so I did not click on it the first 5 times or so - but I finally watched the ad, checked out the company, and ordered one. Summary Findings: 1. It DOES work. You can put the Bondry into a hydration bladder and just put it away (even with the hose attached). It wicks the moisture up and evaporates the moisture away. 2. I HATED having to cut it up the middle to have it fit a bifurcated bladder (e.g. Camelback) - BUT, Fossil Outdoor now makes the WishBon which comes pre-cut. (They also have a Lil Bon for the smaller openings on many collapsible bottles / dirty bags. 3. All of the Bondry products are made with biodegradable / recycled materials and are machine washable. 4. The company is the real deal. The inventor is a hiker guy with a background in earth science and engineering running out of his home. Customer service over and above.
