Here's how it works. On a website, you are guided with video to take 15 different measurements of your own body. Carapace takes those measurements, applies custom algorithms to them, then puts those numbers into a CAD file, and presto, each panel is the precision cut so when the whole suit comes together it fits all of your body's little freaky weirdnesses just perfectly.
I've heard of custom drysuits but can't say I've heard of custom wetsuits. This might just be the ticket if you're an odd shape like me :-P
