about the laminar lip, My previous post was before I received it. The lip slips over the large screen, picture a lower case h with about a 1/3 " that presses onto the screen. The ip moved the wind from my eyebrows to the top of my head my wife claimed no relief from buffeting, also riding thru a t-storm a puddle/wave knocked it off never to be seen again. It works but is ugly and can come off.
