Taking a half upcycled, half organic cotton yarn from the same mill we get our 100% upcycled cotton blend we have had to make this fabric ourselves from scratch with a knitter in South Carolina. Coming in a natural untreated, a bleached white, and fabric dyed black we have made these 100% in the USA from start to finish and all the sewing is done in North Carolina. With a weight of 5.9 ounces in weight and pre-washed and dried these long sleeves and tees are built for comfort. Adding a USA made 1930s shuttle loom label is the final touch in making these a new staple of the brand. Fit: These tees are standard sized or even lean a bit wide in the arm and body, but are not over long in the body.  SIZE GUIDE:             CHEST              LENGTH           SHOULDER  XS                                 17.5"                   26"                         17" S                                    20"                      26.5"                     18.75" M                                   21.75"                27.5"                     19.5" L                                     24"                     28.5"                      20.5" XL                                  25"                     29.5"                      21.75"   Details: Double needle binded collar Pre-washed and dried for comfort
