The Stella GP Pro Comp V2 features an outer shell plain material developed exclusively for Alpinestars which is combined with a soft aramidic base knit lining for optimum levels of comfort, protection, light weight, and comfort. Thanks to the introduction of the aramidic baselining with an open weave structure, this suit delivers enhanced levels of breathability breathable, and this is reinforced even further by the strategically-positioned knitted stretchable open mesh panels on the back, crotch and armhole for additional airflow and flexibility, both in and out of the car. This suit also incorporates innovative silicon grip technology detailing on the shoulders and lower back to prevent any movement with the car’s seat or a HANS device, and also to reduce pressure on the shoulder.
