Choose the size you’d normally buy in men’s clothing. The manufacturer provides this chart you can use to select a size based upon your chest measurements. We find the chart is a pretty good representation of actual fit. These jackets do not taper much at all and have a relaxed fit. Also the fabric is somewhat stretchy. The belly shouldn’t be a problem for most
