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

Super easy to use and very effective at clearing out the moisture in a water bladder. So happy with this purchase!

I 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.

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.

Hands down the greatest purchase with my hiking gear. I started researching hiking gear and saw this. I read about it and was like what does it do? This bad boy sucks the water out of your bladder!!! Prevent mold from developing. You can cut it down to size if needed. Simply wash bladder shove in and walk away. You can have the bladder lay flat. Buy now!!!!!!!

In my experience it takes less than 24 hours to dry. Great little solution.

Has worked great the 2 times I’ve used this. Drys out my bladder great.

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

If 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.

This is a fantastic product. Love this and can’t do without this anymore. I use this several times a week for my hydration bladder. Makes drying so easy and complete. No need to try to keep it pried Open or upside down.

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!
