I bought a pair of the nice zippered ones a couple seasons ago for the cedar river sockeye project...rowing a boat 5 days a week and a average of 2 miles walking a day.
Started in Sept, ended in mid February.

They had bad scuffing and rash along the inside seam, and piling on the seat and the main zipper was getting rough just to name a few problems. I was not impressed...

I pulled them back out for a wetland project I was on 3 months ago and decided to flex seal the inside and outside...that worked okay lol
