I Just got a new Apollo drysuit from your shop. From the instructions, I get the idea that for long-term storage I should hang the drysuit (with feet on the floor). I'm not sure if the fastener is to be closed or left open. The instructions say leave fastener open for short-term storage (arms folded over folded up legs). Should I leave the fastener open when I hang it up as well?

With mine, I personally close the zipper. It hangs better that way and doesn't seem to stress the zipper.
