Hi all, I just switched over to a CB-3000 from The Curve and I can say it's much more comfortable and easier to wear under clothes. However it's NOT as easy to keep clean. The Curve was pretty much open and you could spray water in to keep things clean, not so with the CB-3000. I noticed that there are outlines of additional openings in the molding, you can feel them from the inside. Can those openings be punched out to make more ventilation? I don't know as I've seen any pictures with that being done. Maybe they are just there from the molding process?
