I'm in need of new gear from my get off last summer and have some questions. One of the few times I road and did not zip and it got me, mysterious puncture. I have always used the full zipper even though the small one was there. Most gear only has the small zipper. Has anyone had the chance to use the short zipper in an incident? Did it work as needed? As for the track, can the short zipper still pass for a TD?
