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

I had to modify mine to fit my Camelback reservoir (it has a rib running down the center, so I followed the instructions and carefully cut a slot). I wipe out my reservoir with a paper towel and then leave the BonDry in for a few hours to complete the wicking of the residual moisture. Effective!

I was skeptical that this would work. I didnt really understand how it possibly could be that effective. But I gave it a try, and by golly - it works like a charm! My hydration bladder is completely dry after just a few hours with this thing in it. Even the hose! Other solutions just didnt work well for me, but this! This is the answer.

I 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.

Ive never had mold grow in my hydration bladder so its doing exactly what its supposed to do. I highly recommend to anyone that uses a pack. (For reference, I use mine in an Orange Mud.)

I bought a longer one of these directly from the company, hoping it would help me dry an Osprey 2.5 liter bladder. Maybe it’s fine for a much shorter hydration bladder, but even their longest is lousy for the Osprey 2.5, since barely 1” sticks out for evaporation. It worked, more or less, until the weather got a little humid (60rh); and now, after using the thing about 5 times, I find it is curling up and won’t lie flat. Pretty disappointing for $30+shipping.

Got this to help dry out my hydration packs and it works very well. Its certainly NOT a gimmick and is a fool proof way to keep your hydration bladders dry after cleaning.

Works beautifully. I am happy with this purchase.

Does not dry as quickly as advertised. Use rolled up paper towel and accomplish the same thing. I would not recommend.

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)

Great time saving solution! So nice to shorten my routine before and after bike rides. Works very well and the company supports their product well!
