STUDDS HELIOS EFFECT GLOSSY BLACK GREY N4 GREY D/V (L)
Ride with advanced protection, premium clarity, and race-inspired aesthetics wearing the STUDDS Helios Effect Full Face Helmet. Adorned in a striking Glossy Black Grey N4 design and tailored in a Large (L) size, this helmet is designed from the ground up for riders who demand top-tier features alongside aerodynamic highway stability.
Dual-Certified Shell & Structural Safety: Constructed from a premium, high-impact grade of engineering thermoplastic, the outer shell provides exceptional penetration and shock resistance. Paired internally with a multi-density Regulated Density EPS liner, it works continuously to manage and dissipate impact energy. The entire structure is fully dual-certified to meet both global DOT (US) and domestic ISI safety benchmarks.
Advanced Dual Visor (D/V) & ANTIFOG100 Performance: The multi-visor setup includes a scratch-resistant outer clear shield loaded with a pre-installed ANTIFOG100 lens that yields up to 100 seconds of continuous fog resistance—nearly three times the industry standard. A secondary inner sun visor quickly drops down at the flick of a switch to eliminate blinding midday glare, while the one-touch quick-release mechanism allows tool-free visor swaps.
Dynamic Aerodynamics & Smart Interiors: Cut through the wind with zero buffeting or neck fatigue, thanks to an aerodynamic shell shape integrated with a functional rear spoiler. This works alongside a Dynamic Ventilation System featuring massive dual top vents and a chin intake. The interior boasts a fully hypoallergenic, removable, and washable inner liner crafted from moisture-wicking fabric. For modern connectivity, it is equipped with built-in grooves for prescription glasses and dedicated speaker pockets for Bluetooth communication units. It secures effortlessly using a quick-release micrometric buckle with a rustproof stainless steel frame.
