| Rolled or fold-under smooth-skin seals. This seal, often found on dry suits, is a long cuff of neoprene with smooth skin on the outside that you roll or fold under so the smooth-skin side seals against your bare skin. It's a very efficient seal and easy to apply, but it tends to be a bit bulky.he downside: wetsuits with smooth-skin interiors, with some notable exceptions, are more difficult to put on and take off, and the inside of the suit is more prone to damage. The trend in recent years, especially in 7mm suits, is toward more stretchy neoprene to increase comfort and flexibility.
