I leave my wetsuits and drysuits hanging in the garage all summer and all winter. Still diving the same 12 year old drysuit I’ve been storing this way the past 10 years. Still have my wetsuit from 11 years ago hanging there, too, and it’s OK except I’m too fat for it now. The second wetsuit (3 years old and fits me) is hanging right next to it and has survived 3 summers and 2.5 winters here. When they are not hanging, they are rolled or folded up in the bed of the truck, riding back and forth to dive sites in the sun and the rain. I do take the time to unfurl and let them dry out when they get wet (from rain or from diving). Then back they go to the devil-may-care storage situation.
That said, I am a great fan of the dive all year solution. Buy yourself a used drysuit. You can find them for a couple hundred bucks on eBay (probably cost you a fortune to ship half-way round the world, though).
