BōnDry Hydration Pack Dryer simplifies maintenance in one easy step

I am an outdoor enthusiast who regularly engages in activities like hiking and occasionally trail running. So, I understand the importance of proper gear maintenance, especially when it comes to hydration packs. Few things are worse than getting mildew in your hydration bladder.  So when I discovered the BōnDry (pronounced Bone Dry) Hydration Pack Bladder Dryer by Fossil Outdoor Inc., I was intrigued.

Anyone who has used a hydration pack knows the frustration of trying to get all of the residual water out of the bladder. Whether I trying shaking it out, freezing it, or even trying to rig it up to air-dry, I haven’t found an efficient method. However, the BōnDry Hydration Pack Dryer is designed to efficiently and effectively dry out my hydration pack after each adventure.


Excited to test the BōnDry’s capabilities, I load up my hydration pack and hit a local trail. Curious about its versatility, I have two of my kids grab their Mini-MULE CamelBak hydration packs as well. After a beautiful hike we head back home to see just how effective and easy the BōnDry is to use.

Using the BōnDry Hydration Pack Dryer is a straightforward process. I simply disconnect the hydration reservoir from my pack and empty any remaining water. (It is important to rinse any non-water liquid out of the reservoir before using the BōnDry). Then I insert the BōnDry into the opening of the reservoir and watch it complete absorb any remaining water in my hydration bladder. The wicking process quickly transports the water out of the bladder reservoir to evaporate.

This means that I need to leave my hydration reservoir open for a period of time with the BōnDry inserted in it inorder for it to completely dry. While this is faster than the traditional air-dry method and does a better job, it also means I need one for each of my hydration packs for maximum efficiency. Additionally, the BōnDry doesn’t come with hydration tube and reservoir cleaners like similarly priced air-drying products.

In terms of performance, the BōnDry Hydration Pack Dryer impresses me with its effectiveness in removing moisture from my hydration pack. Even in humid conditions, it quickly and efficiently dries out my gear, ensuring that it’s ready for my next adventure. I also notice a significant reduction in odor and bacteria buildup since incorporating the BōnDry Hydration Pack Dryer into my gear maintenance routine, which gives me peace of mind knowing that my gear is clean and hygienic.


One of the standout features of the BōnDry Hydration Pack Dryer is its versatility. It fits in a variety of hydration bladder sizes, so I can clean and dry the whole family’s gear with one product. (Note: you can cut the BōnDry between the two center seams or order WishBōn pre-split version for bisected bladder models). What use to be a multi-step, extended process is reduced into a few minutes. This versatility adds value to the product, as it eliminates the need for multiple drying solutions and streamlines my gear maintenance routine. It even works on insulated water bottles.

The BōnDry Hydration Pack Dryer boasts a compact and portable design, making it easy to transport and store when not in use. It is constructed from durable materials, ensuring longevity and reliability. Its sleek and minimalist design blends seamlessly with my outdoor gear, adding minimal bulk to my pack.

While the BōnDry Hydration Pack Dryer excels in many areas, it truly works best to simply insert it into the reservoir and put it away until the next adventure. The patent pending moisture transportation technology absorbs moisture quickly leaving the bladder fresh and dry, removing moisture that can cause germs. Personally, I love that it is reusable, sustainably sourced, and made in the USA.
