🪖 ALPINESTARS SM3 HELMET – HEAT EDITION | GLOSS YELLOW FLUO / BLACK (LARGE) | PISTON TWISTIN

Turn heads and stay protected with the Alpinestars SM3 Helmet – Heat Edition. Designed for riders who live wide-open, this helmet delivers race-level protection, aerodynamic performance, and aggressive styling — perfect for track, street, or off-road use.

⚙️ ENGINEERED FOR MAXIMUM PROTECTION & LIGHT WEIGHT

• Varied-thickness outer shell construction optimizes impact absorption while keeping weight ultra-low for reduced fatigue.

• 6-piece EPS liner uses three distinct densities to disperse energy effectively across different impact zones.

• Polished inner EPS liner features a friction-reducing coating, minimizing rotational forces in angled impacts and enhancing comfort liner glide.

🧠 PRECISION FIT & COMFORT

• Includes one outer shell and two inner EPS liner sizes for consistent fit and protection across all head shapes.

• Optional ± 5 mm cheek pads allow a tailor-made fit, letting you fine-tune comfort and support for any riding style.

• Lightweight design ensures all-day comfort — whether you’re pushing pace or cruising the backroads.

🏁 BREAKAWAY VISOR SYSTEM

Safety meets innovation with the breakaway visor, engineered to release smoothly during high-energy impacts. This reduces rotational stress and enhances neck protection when things get sketchy.
