This jacket is sold in “alpha” sizes (Small, Med, Large, etc). Generally speaking, the sizing of Spidi jacket run about one size smaller than normal US men’s alpha sizing. We’ve confirmed the smaller sizing through measurements and by trying them on our /info_pages/motorcycle_gear_fit_check.html. Spidi’s standard sizing chart for men confirms the smaller-than-normal fit. Our basic advice is to buy one size larger than you normally wear in men’s clothing.
To help you confirm the size you need in this jacket, I’ve put together the sizing chart below. You’ll want to measure yourself with a tape around both your chest and belly and choose a size using the chart. We’ve included a waist/belly measurement so you can make sure you are buying a jacket that is large enough for both your chest and belly.
This jacket is fairly trim cut, but not overly so which means most body types will do just fine with it. Those with a waist that is trimmer than the chart indicates for their belly size can use the adjustment straps to customize the fit with no problem.
Jacket Size | Max Chest | Our Estimate of Max Belly/Waist |
---|---|---|
Small | 37 | 34 |
Medium | 39 | 36 |
Large | 41 | 38 |
XL | 43 | 40 |
XXL | 46 | 43 |
XXXL | 48 | 45 |
Note: If you plan on adding a back protector to this jacket, add 1” to your chest and belly measurements before using the size chart. If you plan to add the Thermo Jacket Liner also add 1” to your chest and belly (or 2” if you plan on adding both).
For reference, you can also have a look at Spidi’s standard sizing chart which includes similar chest size estimates along with recommended heights for each jacket size.
