LS2 Stream II Full-Face Helmet with Sun Shield - Matte America Gray/Black - X-Large

Overview

The LS2 Stream II is built for street riders who want premium protection, thoughtful comfort, and modern tech without a premium price tag. It combines an aerodynamic shell with an integrated sun shield and a ventilation system designed for active riding. The shell uses LS2's Kinetic Polymer Alloy (KPA), blending microscopic aramid fibers with high-end polymers to balance energy management and flexible performance on impact. AREM (Advanced Rotational Energy Management) technology softens rotational forces, aligning with contemporary safety expectations while maintaining a nimble feel on the road.

Key safety and engineering highlights

• ECE 22.06 rotational impact compliance
• DOT FMVSS 218 safety standard alignment
• Kinetic Polymer Alloy shell with aramid nanofibers for energy distribution
• AREM rotational energy management reduces risky motion in impacts
• Pinlock-ready Class A polycarbonate shield with integrated sun visor

Comfort and fit for real riders

The Stream II uses an intermediate oval fit profile, complemented by 3D laser-cut foam cheek pads and a removable liner featuring a flex-crown system. This design supports easy cleaning, stable wear, and comfortable distances between stops on longer rides. With three shell sizes and five EPS densities, you’ll find a blend that matches your head shape and riding style.

Ventilation and visibility

A rear spoiler drives dynamic flow-through ventilation, helping you stay cool as speeds rise. The shield is clear by default, with tinted shields available separately to suit lighting and glare conditions. The shield is Pinlock-ready to minimize fogging, supporting clearer vision in variable weather or traffic.

What you get and who it suits

Designed for street riders who value protection, comfort, and versatility, the LS2 Stream II is a capable all-around option for daily commutes, weekend runs, and spirited rides. Real-world benefits include enhanced visibility in changing light, all-day comfort during extended sessions, and a helmet that accommodates growing needs thanks to multiple shell and liner options.

Care and maintenance

• Removable, washable liner
