How do you check your size? Get your favorite T-shirt, lay it on a flat surface and measure the width across the chest (from armpit to armpit). Double it. So for example, if your T-shirt measures 21 inches from armpit to armpit, you should double it to 42 inches. Check the table above. In our example a 42 inch measurement would equate to a men's large. Remember the measurements above are the measurements of the shirts themselves (not the person who wears them).

Sizes are approximate - there may be slight variations between shirts.

These t-shirts run slightly smaller than other brands like Hanes, Gildan, Fruit of the Loom, etc. If you are usually between sizes I would recommend choosing the larger of the two options.

Washing instructions: Wash warm (30°C/86°F), do not bleach, dry low. DO NOT IRON THE PRINTED AREA! Most shirts can shrink very slightly after their first wash.
