CAPHOTOG - I tried the fabric filter wallets too and the nice B+W’s OEM vinyl/polyethylene square containers, both take up too much room in my camera bag or a waist pouch.
(While the filter stack cap concept is many decades old - it still works.)
Only one viewpoint, everyone has to find what works best for their needs and efficient work flow.
Good luck with a solution that works for YOU.
JOEKELLEY – regarding CPL’s, I initially had the same reaction, but found CPL’s fine with a few attempts (i.e. it is all in how/where you hold your fingers on the CPL & wrist action).
Perhaps I have an advantage re: CPL’s, being a petite female with therefore petite hands.
