We tried on and measured a size Medium suit and an XL suit. If you take a close look at the max chest listed for each size suit you’ll notice that the suits are sized about one size smaller than other “alpha” sized products. For example, I have a 45 chest and typically wear an XL shirt. The XL Centurion suit fit well on me and that is the size that I would typically wear in men’s appearal. So my advice would be to check your chest and belly with a tape and use the chart to select a size. Or, if you don’t want to bother with that, just choose the size that you normally wear in men’s clothing. The waist has effective adjusters and will snug down even smaller than our minimun stated measurment if needed. Also there are some adjusters on the arms and at the calf. When in doubt, choose larger as you will be wearing the suit over base layers or street clothes and you don’t want to struggle getting it over your shoulders.
