LS2 Stream II Full-Face Helmet with SunShield – Gloss White (X-Large) | ECE 22.06 & DOT

Enhanced protection for everyday riding

The LS2 Stream II blends premium protection with practical everyday comfort, making it an appealing choice for street riders who value reliability and value. The shell uses Kinetic Polymer Alloy with aramid fibers, engineered at the nanoscale to balance strength, flexibility, and energy management while keeping weight manageable.

With advanced rotational energy management (AREM) technology, this helmet is designed to respond to real-world impacts by distributing forces and maintaining stability. It also carries both ECE 22.06 rotational impact considerations and DOT FMVSS 218 certification for dependable, street-ready performance.

Engineering that adapts to you

The Stream II uses three shell sizes and five EPS densities, so you can find a fit that feels snug without pressure. Inside, 3D laser-cut cheek pads and a removable liner with a flex-crown system deliver a comfortable, day-long fit and easy cleaning.

• Three shell sizes and five EPS densities tailor the fit across sizes
• 3D laser-cut cheek pads for a contoured, comfortable feel
• Removable liner with flex-crown system simplifies cleaning and customization

Vision, shield, and climate control

The shield is optically correct and Pinlock-ready, helping maintain clear vision in varying conditions. The integrated sun shield provides versatile glare control, letting you ride with or without tinted shields (sold separately).

• Pinlock-ready Class A polycarbonate shield for fog prevention
• Integrated retractable sun shield for glare control
• Clear shield ships with the helmet; tinted options are available separately

Ventilation and on-road performance

A rear spoiler supports dynamic flow-through ventilation, helping air move through the helmet as you ride. The combination of vents and the shell design aims to keep you cooler on hot days and comfortable during spirited rides.

• Rear spoiler enables continuous airflow through the helmet
• Vent design supports cooling during long rides and aggressive riding

Notes: The Stream II is a DOT-approved helmet with ECE 22.06 compliance for street use. It ships with a clear shield and supports quick shield swaps to match different lighting needs. Designed for an intermediate oval head shape, it emphasizes comfort during commutes, weekend adventures, and everything in between.
