I have saw where some folks but bicycle inner tube over them and saw where someone was using kayack paddle grips. That got me to thinking. So, I rounded up 3 can coozies (you can make 2 covers from each cozie ) Had the wife sew thim into tubes about 2 1/2 inches long. Slide them over the buckles and you are done. Just made these so I haven't used them yet, but it looks like they will work real good. I had her sew them with the colored side out and then turned them inside out so they are all black.
Hopes this helps out someone
