Sizing Information
This product is sold in European sizes. We measured a selection of these jackets and also tried them on our Fit Check mannequins. The overall sizing of the jackets is pretty much what we expected as compared to other Alpinestars jackets. The measured chest of these jackets run at just about 10 points smaller than the Euro size, so a size 56 Euro has a max chest of about 46”. If you have experience in fitting recent models of Alpinestars sport jacket, you’ll find this one fits comparably.
This jacket, being a sport style, is cut to fit snug and close to the body, but the taper from chest to waist isn’t as severe as you might find in more track oriented jackets. In this jacket, the taper from the chest to the waist is about 2”-3”. Those with a belly need to be careful about size selection to make sure the jacket will be big enough for both the chest and belly. To choose a size, I’d suggest you measure yourself with a tape and get your chest and belly size. Then you can use the size chart to pick the smallest size jacket that will be big enough for both your chest and belly using the chart below. If your waist is smaller than the “max” indicated in the chart, you can still have a good fit here by using the side waist adjusters.
Sizing advice for adding option armor: Adding chest or back armor to this jacket will change the fit. To account for that, I’d advise you to add one inch to your chest measurement if you plan to add a back protector before making your size selection from the chart. Add another inch if you want to add the chest protectors.
