368 Muscle Shirt Size Guide

All measurements shown below are approximations. Length and chest vary slightly from shirt to shirt. Our measurements are taken from a sample of shirts. Length is measured from the front collar to the bottom hem. Chest is measured around the chest just below the underarm. All measurements are in inches.
'Chest Relaxed' refers to our measurement of the shirt by lying it flat surface and measuring it from armpit to armpit and then doubling that measurement to give a full around the chest length.
'Chest Stretched' refers to our measurement of the shirt from armpit to armpit as we stretch it out. We do not overstretch it - just till it starts to resist. As you can see the shirts naturally stretch quite a bit.
To choose your shirt size, we recommend that you measure your chest all around just below your underarm. and decide on the length you need and the desired tightness. Most people are able to put on just about any size, but some people like the shirt to be more skin tight while others want a loose hang.
If you are tall look carefully at the length.
