Check out our USA size chart below and make sure you select the right size at checkout. Keep in mind that you might need a bigger size if you wear a sweatshirt under the protective shirt.
As a rule of thumb, choose your regular size. If you want to wear a sweater under your Protective Shirt, we recommend that you go up one size.
Fernando, 160 pounds (72kg) with a T-Shirt: Medium. Fernando, wearing a sweater underneath: Large
Jason, 180 pounds (82kg) with a T-Shirt: Large. Jason, wearing a sweater underneath: Extra Large
