We know that metal zippers are a big problem that the automotive build industry has been dealing with for forever. Many build shops do not even let metal zippers in their buildings! So Dan set out on a journey to develop a 100% plastic zipper system. With plastic slide, pull, and teeth there is no metal whatsoever in the zipping system with which to scratch precious paint jobs.
While Dan was developing the zipping system he also created a pass thru pocket that allows you to store your items in the front pocket but also reach through to warm your hands on the second set of pass thru pockets.
