I guess I would opt to get the double tin then. I know they are more expensive but I have a Filson vest, jacket and the two pair of chaps and they never seem to wear out. As a matter of fact, my Columbia brush pants (a gift from someone) are on their last leg after only 3 years and I'm replacing them with either the Filson or Cabelas Stonewall bibs.
Filson is as tough as nails and I only recommed them to people who hunt as much as we do.
