I'm looking to get into some more cold water diving. I'm not ready to invest in a dry suit, but I am interested in a semi-dry. However, I'm a very big guy. I'm 6'5" (~196cm) tall, very wide shoulders, and just large all around. In wetsuits, I usually wear Pinnacle brand size 3XL, which can be snug. I see Pinnacle has one model (Merino Polar) in large sizes. Does anyone of similar stature have experience with this? Other recommendations for a semi-dry in big AND tall sizes? I feel a little more wary since the integrated hood means the length is even more important and since no LDS near me ever stocks anything in 3x, 4x, etc sizes. Thanks!
