Motorcycle Jacket back ventilation

This is another jacket ventilation design, It seems to complete very well the other design that I made (see my other jacket ventilation system). I just took it out for a spin and I especially noticed it working, even more than the one I have mounted in front (see my other designs...again). I will update on the design to make it even better looking :)) now that I can see it works pretty well. At first I thought I would be placing the lip underneath the leather, but then I changed my mind. You can do either but then it would be better to place the double tape on the upper side of the lip. There is a version with my nick on it and another one with nothing written. Be cool and ride safe!
