Sizing Information:
This product is sold in European sizes. You can choose a European size based upon your US chest size using Alpinestars’ sizing chart. And for those who may have a bit of a belly, we encourage you to consider our estimated max belly sizes listed below. Choose a jacket size that will accommodate both your chest and your belly. Keep in mind that this is a highly fitted jacket, so choosing a size based upon these recommendations will result in a snug fit which should be comfortable while sitting on the bike, but may be restrictive while standing and walking. Those who don’t like a snug fit should either consider another style or buy one size larger than recommended.

The Moto GP Jerez leather jacket is a great sport/race style jacket with several high tech features. It’s made of thick leather which offers excellent abrasion protection, and the armor in this jacket is very substantial. The elbow armor is a CE approved GP style and is secured to the jacket with Velcro right to the leather shell so it is adjustable and securely held in place. The armor for the shoulders is a CE approved GP-type protector. This jacket also includes some foam armor pieces in the chest area (upgradable to the “Bionic” chest protectors below). For back protection, the jacket comes with a foam pad, but this can be upgraded to a CE approved RC back protector (also shown below). The RC may prove to be too bulky with the speed hump and chest pads, but it would be worth a try. Like some race suits, this jacket has the race hump in back. The hump on this jacket is not as big as some… I’d say about one half the size of the hump you’d see on a full-on race suit. The purpose of this hump is to provide a bridge between your shoulders and the back of your helmet in case of a fall. The hump would help keep your head from being wrenched forward by your helmet if you landed on your back and shoulders. For convenience, this jacket has two zippered front pockets and an additional interior pocket. This jacket will be best suited for cool to warm weather. Portions of the shell are perforated leather which will help admit some air when it warms up. On the colder rides you can use the thermal vest liner to help preserve body heat. The jacket comes with a full circumference zipper for attachment to Alpinestars pants.
