Highlighted area you can cut into
A simple way to make the Sawyer Mini a great gravity filter is by slightly modifying to hang off objects. Since the 16oz Sawyer bladder has a heat pressed end, it's really easy to take advantage of that and make some holes.
I used a three-part hole punch to create a hole
Find a hole punch to make a hole on sides. A drill can be used to make a hole as well.
Repeat step for the other side.
Run 550 cord through the holes and tie a knot.
Note: Different type of line/rope can be used.
Now your Sawyer Mini Filter can be hung anywhere to filter water!
