The REV’IT! Quadratic jacket lands at $589.99 and occupies a deliberate position in REV’IT!’s leather lineup — below the Hyperspeed 3 Pro ($769.99) and Hyperspeed 3 Air ($719.99), both track-first jackets, and above the brand’s textile street offerings. It is full leather, fully perforated, CE-level 2 armored at all four limb joints, and cut for the rider doing street miles who wants race-derived protection without committing to a track suit every time they leave the garage.
REV’IT! Quadratic: Construction and Protection Spec
The outer shell is perforated cowhide throughout — front upper and lower, back upper and lower, upper arms — with PWR|Shell stretch panels at the shoulders, waist, inside arms, and armholes. A recycled polyester mesh lining runs the interior, with a detachable sleeveless thermal liner included for shoulder-season use. Wind catchers sit behind the front zipper and cuff zipper. The jacket carries Class AA certification per EN 17092-3:2020, the second-highest CE category for motorcycle clothing construction.
Standard protection on the REV’IT! Quadratic jacket: SEEFLEX CE-level 2 shoulder and elbow protectors at all four joints, TPU reinforcement at the shoulders, and safety seams throughout. SEEFLEX is REV’IT!’s in-house CE-level 2 armor — ventilated, soft at rest, rated to EN 1621-1:2012 across temperature ranges. Two upgrade pockets are already built in: a pre-installed back protector pocket sized for the SEESOFT CE-level 2 insert (the SEESOFT AIR Type RV adds $74.99 at checkout), and divided chest protector pockets for the SEESOFT CE-level 1 inserts, sold separately. The protection spec the jacket ships with is solid; the architecture allows the rider to extend it without buying a different jacket.
Street Compatibility: Where the REV’IT! Quadratic Jacket Diverges from the Hyperspeed Line
The clearest gap between the REV’IT! Quadratic jacket and the Hyperspeed line above it is the street-pairing feature set. The Quadratic runs jeans loops at the rear to prevent jacket creep at riding position, a short connection zipper at the lower back for quick jeans attachment, and a long connection zipper for full motorcycle-pants integration. It is also compatible with REV’IT!’s Safeway belts for jeans-specific connection. Two slit pockets at the waist, one inner napoleon pocket, two inner pockets total. Snap-down collar with a soft interior edge, hook-and-loop waist adjustment tabs, cuff zipper. These are street jacket details, not track ones.
The fit is REV’IT!’s tight profile — body-hugging, designed to move with the rider rather than against them. The cut runs slightly longer than the Hyperspeed and Argon series, which is what makes jeans pairing work without an exposed lower back at riding position. Race-derived aerodynamic shoulder armor carries over from the more aggressive jackets in the lineup. The aesthetic is sporty without announcing it.
Price and Upgrade Path
The Quadratic is $589.99 at revitsport.com, available in sizes 46–56 in a standard length. Adding the SEESOFT AIR back protector at checkout brings the total to $664.98. EU sizing applies — REV’IT!’s size guide is on the product page. One sustainability credential worth noting: the leather carries Leather Working Group Gold certification, the highest tier of LWG’s environmental and social accountability standard for leather supply chains. The lining is recycled polyester mesh.
The REV’IT! Quadratic jacket makes a specific argument: full-leather Class AA construction at a street-appropriate price and cut, without the track-jacket features a road rider doesn’t need. The $130–$180 it saves relative to the Hyperspeed line is the cost of a race-fit and race-length jacket that works better in the paddock than it does commuting. If the riding is on the street and the protection standard matters, the Quadratic is where the value sits in REV’IT!’s current leather lineup.
