Alpinestars race fit jackets fit very snug and are meant to fit skin tight. Most people will be able to wear the size they normally wear in men’s clothing, but because of the very close fit, we recommend you measure your chest and belly and also consider whether you will be adding full back/chest/tech air vest armor to the jacket since those take up some room.
In the chart below, we list the Euro sizes offered along with the chest estimate. In the first column, we list what max chest is listed in the Alpinestar’s standard size chart, which, by the way is accurate for most street jackets. And then we’ve listed our estimate of max chest for this race fit jacket, which is about one inch smaller across the size range (so about 1/2 size smaller than normal).
Optional armor and fit: This jacket has provisions for optional back and chest armor OR the Tech Air airbag system. If you opt for either one, you’ll have to add about 2” to your chest measurement before choosing a size from the chart.
Measure your chest and belly, add 2” to your chest to account for adding armor or the airbag and then choose a size jacket from the chart that is big enough for both your chest and belly. This jacket has adjusters on the side of the torso to snug down the belly/waist area if you are smaller than the jacket.
