This is a 7mm wet suit for cold water. I used it only in fresh water (mostly Great Lakes wreck dives) when conditions didn't require going dry. Suit consists of overalls and a vest with hood. Overalls can be worn separately in warmer conditions (like Florida cave dives). Vest could be worn separately too, but I found the fit to be too loose.
Overalls were modified with DUI ballistic knee pads, and I glued velcro onto the left arm for a wrist console (since removed; you can see where it used to be).
Suit is a size XL, so should fit from about 5'11" to 6'2" and 185 to 205 lbs.
