Alpinestars S-M7 Core Helmet — L, Red

Engineered for off-roading racing, this helmet is optimized to offer the perfect blend of superior ventilation and comfort in a lightweight design while a supremely aerodynamic composite shell delivers exceptional impact protection.

An A-head fitment and visor detaching system incorporate Plasma technology at the lower side of the shell edge for optimum energy dissipation in the collar bone area.

The aerodynamic profile features a smooth, streamlined shell free of external channels or load points, and the shell's curvature promotes reduced friction on impact to encourage deflection and efficient transfer of energy away from the head and neck.

Ultra-ventilated construction includes 20 intake and exhaust ports (13 intakes, 7 exhausts) for optimum airflow; the fit can be further customized via interchangeable cheek pads and a removable, adjustable top pad thanks to the A-head system.

Communication systems are supported with a cutaway section in the EPS and earphone recesses on both sides, and integrated channels are provided to accommodate a hydration system.

Interior linings are removable and washable by hand with warm water and neutral soap, fabrics receive antimicrobial treatment, and the crown pad and neck pad are elastically connected for better oblique impact management.

Cheek pads use 3D foam with an emergency extraction system and include a channel for hydration tube installation; the chin strap is fitted with a 25 mm nylon web and stainless steel double-D rings with removable covers for washing.

The visor detaching mechanism is engineered to release under impact energies greater than 15 joules to avoid concentrated load points, and strategically integrated Plasma side pads provide high-performance shock absorption in a critical area to reduce injury risk.

Construction composition: 42% fiberglass, 20% polystyrene (EPS), 10% polyurethane, 8% polypropylene, 5% polyvinyl chloride, 5% steel, 4% polyamide, 3% acrylonitrile-butadiene-styrene, 3% polyester.
