Review: Alpinestars Jaws Leather

Reviews and tests 14 November, 2016

We analyze...

The Alpinestars Jaws Leather is a proper sporty leather jacket designed for street use but with all the security elements from a track suit. Made with full grain leather, offering ventilation system and removable thermal lining, this is a versatile sports jacket, designed for use in both summer and winter.

Construction and materials
As mentioned, the main material of the jacket is the full-grain leather, the best quality. With a thickness of between 1.2 and 1.4mm, the Jaws Leather offers a remarkable resistance to abrasion. To gain mobility, it has microfiber in the armpits, the nape of the neck, the inner side of the arms and the waist, as well as accordion panels of the same material on the shoulder blades and elbows. All this, along with the sleeves of pre-curved design, enhances its clearly sporty ergonomics.

In the interior we have a fixed lining totally perforated, own of a sports jacket, but also of a winter liner removable. This 80 gram thermal liner makes the Jaws Leather into a multi-season jacket, capable of rolling in moderate winter temperatures (to give you an idea, mid-winter textile jackets use 100/120 gram linings). In the neck and the sleeves we have a softer fabric to the touch, besides being slightly quilted for comfort.

As for ventilation, the Jaws Leather has two openings at the shoulders to facilitate the flow of air into the jacket. Both zippered inserts are combined by microperforated skin panels on the chest and the area between the nape and shoulders.
The Jaws Leather has Bio-Armor protections on shoulders and elbows, all removable. The shoulders also have rigid dual-density TPU sliders, a technology proven in the circuits by the Italian brand. Complementing these protections, we have foam padding on chest and back. These foams are housed in compartments that can be used to install a Nucleon KR-Ci pectoral protector and Nucleon KR-1i or Kr-2i back guards respectively. Both elements do not come standard with the jacket, being highly recommended.

Closures, pockets and details
The main closure of the jacket is by zipper and velcro flap. The sleeves also have zip fastening, as well as velcro straps at the waist. In terms of pockets, we have two front, with a zip fastening, and one inside the left flap that is waterproof thanks to its fabric and a heat sealed zip. There are also two pockets in the fixed lining and two more in the removable with velcro closure.

The jacket has reflective elements and zip-fitting jacket-pants. Finally, mention that our model, Sergio, measures 1.78 and weighs a little more than 70 kilos, so he equips the jacket of size 50.
Summarising, the Alpinestars Jaws Leather is a top-class sports jacket with regard to safety and ergonomics, but it differs from other models thanks to its removable thermal lining, which will allow us to enjoy the curves during all seasons.
