Alpinestars Supertech M5 Solid Helmet — Size L, White

Engineered for demanding riding conditions, this helmet combines multi-density impact management, precise ventilation, and rider-focused comfort to deliver reliable protection without compromise.

• Lightweight, impact-resistant outer shell paired with a side shell and soft EPS foam to reduce collarbone load in a crash.
• Inner and outer surfaces are optimized to reduce the effects of oblique impacts for improved energy dissipation.
• Multiple-density inner liner places the correct foam stiffness where it’s needed for enhanced impact absorption.
• Emergency release system and removable cheek pads allow safe pad removal while the helmet is on, with 3D contoured foam for long-ride comfort.
• Removable comfort liner treated with Silverplus® antimicrobial fabric for superior moisture wicking; the liner is washable.
• Integrated hydration tube channels in the cheek pads for convenience during extended rides.
• Soft textile chin strap (26 mm) wider than typical certification minimums, secured with stainless steel D-rings for a snug fit.
• Patented visor release system designed to release with a controlled force regardless of impact angle.
• Maximized ventilation with multi-air inlets and exhaust ports, and a visor shaped to direct airflow into those ports for enhanced heat transfer.
• Constructed from a carefully engineered mix of materials to balance weight, comfort, and protective performance.
