Contemporary and clean in design, the Quadratic jacket offers a subtly sporty aesthetic in a highly ventilated full-leather construction. A true sports rider's jacket for daily street rides and sunny days spent chasing curves.

A close-fitting, yet unrestrictive fit
Perforation throughout the front, back, and upper arms blends with a durable yet flexible, yet slightly breathable, stretch fabric throughout the Quadratic jacket. This ensures a close-fitting fit without restricting movement on the bike; the jacket is easily adjustable for added comfort thanks to the tabs along the waist. Impact protection is provided by ventilated SEEFLEX CE-level 2 protectors at the shoulders and elbows, with the option to upgrade to an additional SEESOFT CE-level 2 back protector and CE-level 1 chest protector.
Perfect Pairing with Jeans
Although the Quadratic jacket features race-derived aerodynamic shoulder armor, it's a highly street-ready piece. This means it features pockets around the waist, an additional pocket behind the main zipper, and a slightly longer cut than our sporty rider jackets, such as the Argon and Hyperspeed styles. The Quadratic jacket also pairs perfectly with motorcycle jeans, either using the jeans loops or the connection zipper to attach it to our Safeway jeans-specific belts with zip-on functionality. Plus, thanks to the removable sleeveless thermal liner, you can extend your riding season, even when temperatures aren't ideal or aren't quite there yet.
