By far these are the toughest t-shirts on the market. Have been wearing Wrangler shirts for years an they definitely stand up to the test. The shirts are a little thicker then the average t-shirt and can be a little warmer so I stick to the litter colors in the summer. The extra holder in the pocket also helps to keep my pen where it belongs. This shirt really holds its shape even in the toughest of environments. These shirts last twice as long as any thing else I've worn. I use to go through shirts every season but these shirts will last me over a year now. All I use to wear was Carhartt but these are a far superior product. I even wear them around the house now. I recommend these shirts to everyone that I work with every chance I get.
