Powerade Bottle Katadyn BeFree Filter Adapter

An adapter I made to mount a Katadyn BeFree filter to a standard Powerade bottle. This will be a useful piece of kit to have with you on a backpacking/backcountry trip if you use the Katadyn BeFree as your primary filter. Take a few empty powerade bottles with you to keep clean water in; then if your bladder breaks, you can switch to using them for dirty water and just mount the filter right to it. I now have one of these in my kit.

Because the filter wasn't designed to go inside the bottle, it kind of protrudes off the top of the bottle quite a bit; but the actual adapter itself is pretty lightweight and doesn't add much of any weight penalty to your loadout.

Adapter dimensions: 8.4cm (height) x 4.2cm (diameter at widest)
