Style: 100% preshrunk cotton unisex crew neck shirt You may use the drop down menu to select your preferred size and color for your shirt. Please refer to the sizing guide (width/length in inches) below to determine which sized crew neck shirt is best for you: Small: 28/18 Medium: 29/20 Large: 30/22 XL: 31/24 2X: 32/26 3X: 33/28 4X: 34/30 Please verify with color charts your size/color combination. Not all shirt colors go to 5x No matter which shirt you choose you will be treated to a piece of clothing that features only professional grade ink applied using a commercial machine. By pressing it into the fabric at over 300 degrees and 40+ PSI I am able to create cotton shirts that can better withstand washing and wear. Smoke free home but I do have 2 dogs.
