Sew in an 1/8" elastic bungie cord and put a cord lock on it. Easy to cinch up or loosen to remove. No belt needed or loops.
That's what I should do! Just buy what works instead of "cheaping out" - those are very reasonably priced, thanks Dean!If it doesn't work, take a look at these.
I initially bought mine for occasional use and they have become my goto unless wading deep.
