@tursiops very sorry, busy weekend working on everything but diving. Here is the links to the ones I got. They are a little snug, i find it helps a lot to hold it closed while doing the zipper. Once it's closed it feels pretty solid. I used to be worried they would get messed up in my little dive bag because they were loose. I think this takes care of that. Time will tell.
I have not gotten around to the covers yet. Good thing, I'll try the 38mm to start.
