A recent post go me thinking of Rockys MM PV casuals as swim kilts. They dont carry much water and dry pretty fast. The problem is the leather belt. I would feel a lot more secure coming out of the water in a heavy kilt with one.
Thinking of making a 2 or 2.5 inch polyester web belt. First thought is get the seat belt out an old 60s-70s car. It has a buckle already would just need to sew the buckle mate onto the other end. These predate the auto tensoners so it would adjust like a regular web belt by pulling the tag end. Hmmm.
