Yesterday on a day hike I was wearing my old Zpacks cuben fiber jacket (it is a weird white color and has a very plastic feel to it, it’s not one of their newer jackets) and I kept feeling this catching sensation as my arm brushed against the strap adjuster on my day pack. I looked and the seam had torn open on one of the arms and was coming close to doing the same on the other arm. The seam itself feels sticky like it had been glued.
I’m wondering what’s the best way to fix this. I find that duct tape tends to peel away at the corners or edges of things that I’ve fixed using duct tape.
