T-Shirt Size Guide

The best way to order the right size is to measure a t-shirt you already have, that fits you well. Lay it flat, and measure straight across the front from armpit to armpit. Then compare that number with our size chart.
 
We use AS Colour for our apparel as they are ethically produced and of the highest quality.
