Size Chart

Garment sizes are tough, two shirts both say “Adult Large” might not be the same size. These charts show the measurement of the shirt as it lays flat on a table not measurements on a person. “Width” is measured from below where the sleeves connect to the body of the t-shirt and “Length” is measured from the bottom hem to the top of the collar.
Key: Y=Youth, A=Adult, Shirt dimensions are torso width x total height, imprint is WxH
