I'm in my third season of using a custom-fit SupSkin "Ultimate" drysuit for SUP sessions, both flat water and downwinding but not surfing. I didn't fit any of their stock sizes.
Pros: easy on, easy off. No movement restriction while paddling. MUCH more breathable for high exertion work where I'm sweating a lot. I overheated in wetsuits. I just wear base layers underneath, regular poly stuff. Good wind chill protection. Plenty waterproof for paddling in the rain and the occasional dunks. Latex cuffs except at the neck, which is neoprene for comfort.
Cons: Pricey, goofy looking, and after 2+ seasons the fabric is starting to wet out quickly. I probably should have washed it more often early on, which is its own hassle. The custom route took 6+ months to arrive and then I had to send it back for an alteration, so there's that. But it's a pleasure now that it fits.
