Other details include glued, taped and blind-stitched seams, pre-bent knees, hems in limb openings that are lined with grippy silicone to prevent them from riding up and, for the guys, a relief opening. Four-way stretch material in the shoulders, sides and arms provides great mobility. The neck opening in the top is made of a soft, stretchy “Glideskin” to prevent chafe and make the top easier to get on and off. Abrasion-resistant panels are on the seat, running well down the back of the upper legs, and on the knees. For dinghy sailors looking to extend their sessions well beyond the warmer months of summer, this kit is your ticket to four-season fun.
