These jackets are sold in US based “alpha” sizes, so selecting a size is basically pretty easy. The size Medium and XL jackets fit Huey and Dewey, our Fit Check mannequins very nicely! Also, we checked several sizes with a tape. We found the sizing to be comparable to standard men’s clothing sizes. So our primary advice would be to choose the size you normally wear in men’s clothing.
Alpinestars publishes a super-complicated size chart which can be used to pick a size based upon your chest and waist. We’ve condensed their chart down to make it easy to read (see below). You can use this size chart to check your own measurements against the size chart to make sure the size you select will work. Choose a size that is big enough for both your chest and belly.
Please note, this style has a slightly more aggressive drop from chest to belly than typical for this type of jacket. Be sure to the max waist/belly is large enough if you have a bit of a belly, but don’t be concerned if your belly is smaller than the size listed below because this jacket has effective side waist adjustment straps.
