The bottom viscous layer sits under the ishial and perineal area for added ventilation in these high pressure regions. Combined, these layers work together to keep you riding comfortably on long days in the saddle. Camlock ankle zippers hold the tights close to your legs so they don't sneak up. The Camlock zippers also let you quickly ventilate by flicking the zipper up and pu...
