Alpinestars S-M7 Deed Helmet — Size L, Purple

🏁 The S-M7 Deed Helmet is engineered for off-roading racing and optimized to offer a perfect blend of superior ventilation and comfort in a lightweight, aerodynamic composite shell that delivers exceptional impact protection.

The helmet features an A-Head fitment and visor detaching system with PLASMA technology integrated at the lower side of the shell edge to help dissipate energy in the collar bone area and improve oblique impact management.

Protection and impact management are enhanced by a streamlined shell curvature designed to promote deflection and efficient energy transfer away from the rider's head, while a visor release mechanism allows the visor to automatically detach when subjected to impact energy above 15 joules.

Ventilation is ultra-efficient with 20 intake and exhaust ports (13 intakes and 7 exhausts, not including the eye port) to maintain airflow during hard riding, plus integrated channels on both sides to accommodate a hydration system and an EPS cutaway on the left side for communication system installation.

• Top pad removable and adjustable in height via the A-Head system.
• Crown pad and neck pad elastically connected for improved oblique impact response.
• 3D foam cheek pads with emergency extraction system (ERS) and hydration tube channel; cheek pads are interchangeable among sizes.
• Chin strap with 25 mm nylon webbing, stainless steel DD rings, and removable covers for washing.

Linings are removable and washable by hand with warm water and neutral soap, and fabrics receive antimicrobial treatment for freshness and hygiene. Communication speakers can be accommodated in earphone recesses on both sides.

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