I think I tried on at least six, 7mm wetsuits before I found the Seac Space, which I have renamed, "Spaceman". I'm about 6', 220lbs and the standard, XXL fits me perfectly, no baggy spots anywhere on the suit. I addition, the quality is spectacular. No shortcuts were taken with the suit, it has zippers and Seac's "Auqastop System" on all of the main water intrusion points, plus the back zipper pull is plenty long enough to put the suit on and take it off easily by yourself. I especially appreciate the zipper at the neck, which takes the pressure off of the collar that some wetsuits can apply to the front/base of your neck. Certifying students at the local quarry is going to be so much easier to deal with in the Seac "Spaceman". Thanks Dolphin Scuba friends!
