Sizing Guide:

1. Match your weight to a size

2. Match your height to an arm length

3. If they match you should be in the ballpark.

4. If you have a soft measuring tape you can measure for arm length. Standing with your arms to your side have someone measure from the center of your neck, over your shoulder and down to your wrist to get a pretty accurate arm length. 

5. If you find your size doesn’t align on the chart please Contact Us to get help. We will continue to expand the size range upon request.

6. Buy one in your size to test it out.

Sizing comparison & notes:

1. Martin Bros shirts will fit about ½ size smaller than Wrangler and one full size smaller than Carhartt in the body. Martin Bros shirts usually fit smaller than other shirts in the body area.

2. All sizing is sized to fit as a welding shirt. Most can fit a hoodie under there regular size (reference next note)

3. Know your body type - if you know you are particularly slender or round in the midsection take that into consideration to know when to size up based on weight. Ex. If you were to be on the tighter side of an XL t-shirt but fit into the XL size MB shirt and want to be able to wear a hoodie underneath you may want to go up a size.

4. Shrinkage - you can expect a little shrinkage over time and especially if you dry on high heat. (.5”-1” on the arm)
