Subtly sporty, fully ventilated leather sports riding jacket. Contemporary and clean by design, the Quadratic jacket offers a subtly sporty aesthetic in a highly ventilated, full-leather construction. A true sports riding jacket for everyday street rides and sunny days spent chasing corners.Body-hugging fit without constraintPerforation across the both the entire front, the back, and the upper arms meets durable yet flexible and lightly breathable stretch fabric throughout the Quadratic jacket’s design. This provides a body-hugging fit without restricting movement on the bike - easily adjusted for further comfort with tabs along the waist. Impact protection comes in the form of ventilated CE-level 2 SEEFLEX protectors at both shoulders and elbows, with the option to upgrade to an additional CE-level 2 SEESOFT back protector and CE-level 1 chest protectors. Perfect match with jeansEven though the Quadratic jacket features race-derived aerodynamic shoulder armor, it is very much a road-going garment. That means it’s equipped with pockets around the waist, another pocket behind the main zipper, and an overall slightly longer cut than our full-on sports riding jackets, like the Argon and Hyperspeed styles. The Quadratic jacket is also perfect for pairing with motorcycle jeans, whether using the jeans loops or the connection zipper to attach it to our riding jeans-specific Safeway belts with zip-on functionality. And with its detachable sleeveless thermal liner, you can extend your riding season when temperatures aren’t quite optimal - or just not yet.
