Sizing Information
These jackets are sold in US based “alpha” sizes, so selecting a size is basically pretty easy. For most people, you would 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). The size XL fit Dewey, our XL Fit Check mannequin very nicely!
The taper of this jacket is about average (meaning how much smaller the waist/belly is than the chest), and will be great for nearly any type of street riders. Alpinestars’s sizing chart lists the recommended waist range and the jacket has a lot of waist size adjustment. Judging by the way the jackets fit and the numbers in the chart, we feel the “waist” sizes they list could more appropriately be considered belly size ranges. Your actual jean size waist could be smaller than what is indicated and you’d still be OK because of the wide range of adjustment offered by the side waist straps.
