I have purchased several K126 shirts from my local Carhartt store and after a few months of repeated use I was pleasantly surprised at the quality, weight and durability of the shirts and thought I would would you get the same from this purchase on the internet. God I was wrong, the K126s I got from the store were Guatemalan and retailed for just under $30 than the version I got from Revain which was made in Mexico. In comparison, my shirt in the store is a thicker, heavier cotton blend and doesn't let the light through when one side is exposed to the light. The Mexico version has a cotton blend, which is lighter and doesn't feel premium. After a single wash and air dry, the shirt also lost a lot of the length and chest space that I was expecting from my K126 and K87 models. You are guaranteed a level of quality control that you don't get when buying online.
