For bigger wings, I think the best option is those little snap buttons (or regular buttons, but theyre more difficult). Theyre pretty secure, you dont have to line it up like velcro, zero risk of sliding down like a zipper. Also easy to do behind your back

Edit: I also forgot to mention the dreaded pinching that can occour with zippers. If the thin bits of a feather get trapped in there its over for you

Sometimes I wonder how my guitar feels when I flip the switch or turn the knobs…
