・Polished air cooling performance provides high comfort.
Specifications:
・Color: Flat Black
・Size: XS (54-55cm)
Sizes are approximate.
Due to product design, the fit may vary even with the same size indication.
・Standard: JIS
Features:
【Ultra Cooling System】

・A newly designed cooling system that allows you to feel the wind from the moment you start riding.
・Ventilation holes are optimally positioned for the helmet's angle during riding, based on wind tunnel tests and CFD analysis.
・Achieves impressive coolness by allowing you to feel the wind even at low speeds.
・(Left) Wind tunnel tests demonstrate that coolness can be felt within approximately 30 seconds of starting to ride.
・(Right) The newly designed chin ventilation system, developed by extracting the optimal combination based on the results of pre-assuming and verifying many patterns such as the number, position, angle, and shape of the ventilations, divides the air intake into two directions: upward to reduce shield fogging, and forward to directly deliver air to the mouth, achieving unprecedented coolness.
The rear ventilation does not have an opening/closing function.
【Interior with a new sensation of fitting that allows air to pass through (HEXA-PAD)】

・By digitizing the space between the inside of the helmet and the head, optimizing the distribution of interior thickness, and varying the thickness of most of the fabric through hot pressing, a new seamless fitting sensation with fewer seams is achieved, allowing you to experience the coolness of air passing through.
【Antibacterial Interior】
Used in some parts
・The inner pad part uses DEOFACTOR's "antibacterial processing" to suppress the growth of bacteria on fibers. DEOFACTOR decomposes harmful substances adhering to clothing and textile products through its antibacterial action.
DEOFACTOR is a special processing technology developed by KOKORO CARE.
【"UV & IR Cut Shield" using heat-shielding material from Teijin Limited】

・Adopts "UV & IR Cut Shield" which uses high-performance polycarbonate from Teijin Limited as the shield material to cut UV (ultraviolet rays) and IR (infrared rays).
・It has heat-shielding performance that suppresses temperature rise due to solar radiation heat generated by infrared rays (IR), reducing heat conduction into the helmet while maintaining "clear visibility," which is the most important aspect for helmet shields.
Internal temperature of the helmet measured in-house by irradiating an incandescent lamp (300W).
【Dedicated mounting space for intercoms】

・Dedicated mounting spaces for intercoms and cameras are pre-set on both sides.
・Cable routes are also installed simultaneously, allowing for smart wiring of cords from speakers and other devices.
Some special shapes cannot be installed.
【Pinlock Original Insert Lens compatible】

・Can be fitted with a 100% MAX VISION Pinlock sheet (sold separately) that covers up to the upper edge of the shield.
【CF-1 Shield System】

・A coverless shield replacement system that enables quick shield replacement.
【Wake Stabilizer PAT.】

・Kabuto's patented system that controls airflow around the helmet shell and reduces load.
【Stylish Compact Design】

・Achieves a stylish and compact design by effectively arranging parts and adopting an optimized shell design.
【Eyeglass-compatible cheek pads】

・The new sewing pattern for the cheek pad shape allows for smoother wearing of glasses and sunglasses.
There are individual differences depending on the shape of the glasses and face.
【Wind Shutter No.7】

・Reduces wind turbulence from around the chin during riding.
・Can be attached and detached as desired depending on the season and use.
【Breath Guard No.9】

・Adopts a newly designed breath guard that expands the blowout area to the inner surface of the shield.
・Contributes to defogging the shield.
【Micro Ratchet Buckle】

・Uses a micro ratchet buckle for one-touch detachment and fine adjustment.
・Multiple interlocking teeth ensure reliable operation and safety.
【T.P.S. (High-Performance Thermoplastic Shell)】

・A thermoplastic shell made of high-performance resin raw material with excellent impact resistance.
【2-Shell】

・Achieves a precise fit by using two shell sizes.
【Micro Ratchet Buckle】

・A chin strap retention device that allows one-touch detachment.
・Fine adjustments are easy with the fine ratchet.
