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

This is a great idea - who wants a slimy hydration bladder? However, mine takes DAYS to dry out so the damp BonDry is sitting in a damp bladder... not sure how this is helping avoid mildew. Im still using it.... but not thrilled. Im sure if you lived in a drier climate it might work better for you... but if you are in the PNW, it might not.

I started using a hydration vest (Orange Mud 2L) and loved it, but my biggest hassle was keeping the bladder dry between uses. The vendor actually recommended sealing it and blowing air into it when not in use, so at least the sides of the bladder werent in contact, which I did for a while, but hated hte idea of mold growing, etc. This guy is perfect for it - wash it as thoroughly as possibly, drain out the water you can, then stick this guy in and it does the rest to keep it dry.

The BonDry hydration pack dryer WORKS. I hike 5 days a week. I have tried several methods of drying my pack however none have completely dried my pack. With the BonDry - my hydration pack is BONE DRY.

The BōnDry (Bone Dry) water bladder dryer is an absolute game-changer for anyone who uses a hydration bladder. I have tried all types of alternative ways to dry the bladder. They work, ok, but no where as good or as easy as it is with the BōnDry. Its a high-quality product that lives up to its promises and makes the process of drying your water bladder quick and effortless... without any lingering moisture or odors. I have purchased the knock-off brand to save a few bucks... MISTAKE! I didnt work as well - not even close as the real deal. I sent the product back and they actually didnt refund me either - double negative from my perspective. Having tried several other options, including the knock-off one, The bone dry is the clear winner that works the way it should and saves me time and hassle. Overall, I highly recommend the bone dry water bladder dryer to anyone who uses a hydration bladder regularly. It is a high-quality, reliable, and effective product that will make your life a lot easier. Five stars all the way!

I have been using them for over a year to dry out my trail running water bladder. Dries it out perfectly. Bought a second pack and use them to dry out my water bottles. Solid product, great value!

Works surprisingly well! I used to have a whole elaborate hanger system and Id have to stuff a washcloth into just the right spot to dry my water bladders. This thing is so simple that at first I didnt think it would work. Just stick it in with part of it hanging out of the bladder. Thats it. No fuss, just a super simple, super effective product. I wish I had this 20 years ago

Excellent product. We hike a lot with hydration bladders in our packs, and this keeps them from getting funky and gross. Highly recommend. I can’t ever get ALL the water out of the bladder bc of the way it’s designed. This sucks up the water and prevents mildew.

I usually have to hang my hydration bladder upside down on a banana hanger over a towel so it doesnt drain all over the counter. It usually takes 4-5 days for the main compartment to dry - the tube takes longer. This was after 12 hours lying flat on the counter. The tube is still wet, but the bladder itself seems dry. Very simple process and good results.

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.

Not much to say. Wicks the moisture out of the bladders and helps keep them from getting nasty. I do plan to buy a few more.
