Our shirts come in adult sizes S-4XL. The most common measurement for t-shirts is to measure around the chest and round up to the nearest inch to determine what your size is (see diagram below). Because our white and ash gray shirts are almost entirely made of cotton, expect the shirt to shrink slightly after you wash it. So, if you are teetering between a medium and a large, order a large for a comfortable, breathable fit.
If you are interested in purchasing a USA-made shirt, please be aware that they tend to run larger than our generic brand of shirts. Please refer to the diagram below for more information.
