Robbie asked me to write my impressions of the suit, so, briefly......Today was my first use of the shorty blacktec. 5'10, 160lbs. I bought the large because that was all that was available. The suit was warmer than my old long wetsuit. Very warm and very flexible. I plan on getting the long blacktec when it is available as I am pretty sure it wll be at least as warm as my dry suit, maybe warmer, and way more flexible,.... for late fall... It fit well, tight in the chest back and waist. Even sk might size down though we'll see. Very satisfied with the product.
