What zipper size should I use for a 1 person bivy tent? I'm in the process of making one.
I wanted to use a size 3 zipper but I feel it could be too small and weak. #5 almost looks too large and heavy and finding something in between
is difficult.
Any clues as to what is the minimum zipper size I can get away with? Anyone used a #3 on a tent before?
Thanks.
