These are pre-owned Patagonia Mountain Utility Gore-Tex Pants - Men's Large.  I used these as a ski patroller for several years, but alas they no longer fit.  No significant stains or tears, but understand that they are in well used condition.  Please review the photos carefully and ask any questions prior to bidding.  Super rugged pants, they still have lots of life to give!
