These jackets are sold in US based “alpha” sizes, but we found them to be oversized by about a size and a half. Icon calls this their “relaxed fit” and it is definitely sized to go over a larger frame or other garments. The size Medium and XL jackets fit Huey and Dewey, our Fit Check mannequins very loosely as you can see if you take the “View Larger Images” link above. We checked several sizes with a tape and developed the size chart below. Our primary advice would be to choose the size you normally wear in men’s clothing if you intend to wear the jacket over multiple layers or body armor. However, if you only intend to wear the jacket over a light layer or shirt then we suggest you try one size smaller than you normally wear.
We’ve developed our own size chart based on measurements we took here at the shop. You can use this size chart to check your own measurements while wearing the gear you intend to wear under the jacket against the size chart to make sure the size you select will work. Choose a size that is big enough for both your chest and belly.
The max waist of a jacket style like this is the same as the chest measurement, meaning it is a boxy fit.
