> 3 dayIf 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.

> 3 dayI received my initial bondry from amazon and it had a foul smell after putting it in the bladder. I contacted bondry via their instagram account and asked if it should have a smell. They informed me to return the one to amazon as this was not the first time they have heard of this issue. They sent me one out directly from them. I have dried the bladder 3 times now and have 0 issues. Great product does the job. Customer service is top notch. I will be buying again!

11-06-2025Works 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.

> 3 dayI was skeptical that this product would work but it really does. You put it in your hydration pack for a couple days (rotating it once) and the water’s all gone. Before the BonDry I kept my packs in the freezer which took up a lot of space but thanks to this product I don’t have to do that anymore.

> 3 dayWish I could have found out about this long before now. Ive never had any luck with other approaches to drying my hydration pack, but this one works perfectly. Cut a slot into it to fit it around the divider in my pack, put it in and it worked overnight. Pack was completely dry the next morning.

> 3 dayThe 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.

> 3 dayIt 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.

Reusable - Care
Machine washable, but we recommend washing by hand to avoid harsh perfumes and cleaners. Pair with BōnDryClean cleansing tablets for best results, or simply a tablespoon of baking soda in warm water. Stretch on a flat surface to dry. You can use the dryer but it may shrink.
How to use:
1) Rinse the hydration backpack bladder or bottle.
2) Insert BōnDry with the tip exposed to the air
3) Put your gear away!
BōnDry will absorb the moisture and then wick it to the exposed tip to be evaporated. Make sure the tip is exposed to the air by slightly unzipping the pack for best results.
BōnDry is the real deal!
If you are tired of trying to maintain your hydration bladder, we have your back!
We invented BōnDry because we were sick of having to try and maintain our hydration pack. Air-drying or freezing just meant that the bladder wasn"t put away making a cluttered mess for days. BōnDry makes the process easy - simply rinse your hydration bladder, insert BōnDry, and put your gear away!
