Hey guys I just solved this otter zipper issue. Currently on the lake, 14 below zero and my Main zipper split and the one side came out. (2018 otter lodge x-over pro) I have a Leatherman with me and I was able to cut the little square of cloth away from the ends of the zipper. Just between the threads where the actual zipper track is so you don’t ruin the seal. Once you have the track exposed on both inside and outside you can take the zipper and put it back on get it started then I used my pliers and squeezed the hell out of both sides works like brand new. Saved this trip!!
