I got a Medium Xterra Vortex 4 Full Sleeve wetsuit recently and then realized that my "better half" already has the exact same size and almost never uses it. No need for us to have 2.
The "retail price" is 400. But xterra suits are ALWAYS on sale. It can be currently had for $180. I've never worn mine in open water and only tested it out once in the pool. It's yours for $130.
I'm 6'0, about 165lbs and it fits well. Here's a link to the sizing chart to see if it will fit you.
