We measured a selection of these vests and found them to fit true to the stated size. Vests are generally very forgiving for fit since they don’t have shoulders, and the waist/belly sizes on these vests are quite relaxed. I’d advise you to choose the size you normally wear in men’s clothing.
We also put the Medium on Huey and the XL on Dewey and they look good. I developed a chart below to show you the max chest and max belly size for each alpha size offered.
