The GP Force Chaser Leather Suit is constructed from bovine leather for unsurpassed abrasion and tear resistance. Fully optimized for use with or without Tech-Air5®, Alpinestars world leading electronic airbag safety system (sold separately), the GP Force Chaser Leather Suit incorporates Alpinestars GP protectors for effective impact protection and external sliders at the joints for unparalleled abrasion resistance. Tech-Air® 5 compatible (sold separately); Tech-Air® is the world's first completely electronic, self-contained, fully independent upper body motorcycle airbag system with no bike-to-rider set-up configurations required. Strategically positioned accordion stretch panel inserts have been designed to accommodate Alpinestars Airbag System, allowing expansion when the airbag inflates but also offering a high level of anatomical performance and a superior fit when riding without the system fitted.
