Hanger vs other ways to hang dry or store:
With modern super stretchy and supple foam wetsuits, folding and storing flat creates permanent creases in a couple of days.
I've had one of my Yamamoto 39 suits on a wide coat hanger with 5,5cm 'shoulders', with a non-slip flock coating - the result was visible marks and slightly thinner foam in the wetsuit shoulders after 2 months.
I've now mocked up this and I feel it will work well. Key point is that the extra padding should have a good grip and distribute the load onto a wider surface.
For drying, I've got a cheap 20$ blow hanger with just 150W power. Does the job overnight. But I needed to tape 2 halves of a wide coat hanger, as the original 'blades' would damage any wetsuit in no time.
Another point about quick drying - a salty suit will never dry completely in a humid environment. The salt just absorbs water from the air. Need to rinse it with fresh water first.
