My Frog Toggs are 5 or 6 years old. No problems with them other than one seam started to come out - probably from pushing thru brush goin' down to the river. Wife just sewed the seam back thru the orig holes [it was the zipper on the jacket]. They haven't torn or leaked. They spend the whole year - in the summer - either in my vest or in one of the bags on my 'toon.
If they aren't there they are in the back of the car in a small bag, so they haven't been pampered. I'll buy another pair if these ever wear out.
