We tried on and measured a size Medium suit and an XL suit, both regular lengths. I thought the suits were comparable to the size chart provided by Joe Rocket. 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 Survivor suit was a bit snug on me and I’d probably select an XXL for myself in this suit. 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 one size bigger than you normally wear in men’s clothing. The waist has effective adjusters and will snug down. Also there are some adjusters on the chest which work well too. When in doubt, choose larger.
The suits are also available in short sizes. If you are shorter than average in your clothing size, then choose a short. I don’t know of a good way to quantify this for you. I found the “regulars” to be adequate for an average height rider, but putting figures on an issue of torso AND pant length would be difficult. You may have to return/exchange, but we are easy to deal with and the cost is minimal (no more than $8.99 for the whole process of a return/re-ship in the continental US). If you are paying for shipping outside the US, then be prepared for some expense if a return or exchange is necessary.
