08-06-2025I 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.

> 3 daySucks 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.

Greater than one weekThese work great for drying hydration bladders, but also I cut one into 4ths and use them to dry silicone hand bottles as well.

> 3 dayThis 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!

> 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.

Greater than one weekThe 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.

> 3 dayThis thing makes drying out my osprey pack a breeze! It didnt work on my sons cheapo pack because the fill hole isnt big enough, not this products fault.

> 3 dayVery happy with my purchase. It actually does dry the bladder. Usually takes about a day to do it, but it is much easier on the environment than my old way of using paper towels.
