LS2 FF399 Valiant helmet


  • Multi-density EPS
  • Bolster
  • Reinforced chinstrap
  • Anti-Fog
  • Anti-UV
  • Scratch-proof

Shell size

  • LS2 offers multiple case sizes, custom-sized EPS protective films and our high-performance, high-quality comfort filler as well as 3D laser-cut plastic foam for a perfect fit and comfort throughout the day

Made of KPA

  • A patented blend of polycarbonate, a space era thermoplastic, and additional materials formulated by LS2, KPA, allow for extra light weight and superior penetration resistance while maintaining flexibility, to a degree, in terms of energy dispersion. The special formula meets the requirements of both the ECE 22.05 and the DOT

The most stable mechanism in the world

  • LS2 introduces the world's most stable mechanism - built into our new flagship product. For those who want to be not only safe but also stylish. The 180 degree rotation of the chin part transforms the helmet from integral to open face in seconds, and vice versa. A masterpiece of technology and research, all in the same product


  • LS2 visors are made from 3D optically correct "A-class" polymers, a space exploration polymer with high resistance to impact energy and maximum visibility. Our visors are stable, scratch-resistant and UV-resistant. All this combined with the ultimate PINLOCK technology provides the most advanced anti-fog standard

Two sighting system

  • A sun visor helps to protect the driver's eyes from strong sunlight. The sun visor moves smoothly thanks to the exclusive mechanism, which is located on the lateral end edge of the helmet shell. This system allows the driver to adjust the view very quickly to the changing conditions, e.g. when driving through tunnels or forests

Including pinlock

  • To prevent fogging of the visor while driving, LS2 recommends Pinlock. A system that prevents the natural fogging of the visor caused by breathing, without having to compromise on visibility

Simple visor removal

  • As easy as wearing the helmet, the change of visor is just as easy. With a simple operation, you can remove and re-attach the visor, for example, to clean or install the PINLOCK disc


  • LS2 helmets have a so-called "Dynamic Flow-through Ventilation". Multiple adjustable inlet ducts and EPS damping with air ducts in conjunction with the rear spoiler and exhaust ducts provide permanent ventilation to provide the driver with cool and comfortable conditions

Quick release

  • The metal buckle combines with a high-quality chin strap with a plastic tongue with teeth. When closing you hear a soft "click". As far as locking until you reach a comfortable but tight seat. Pull the ribbon to unlock the tongue. Further adjustment options are provided by the chinstrap on the side of the metal buckle

Fast sun visor confirmation

  • Quick and direct mechanism to extend or retract the sun visor when needed

Reflective security patch

  • To improve the safety of the driver at night or in difficult visibility conditions, the bolster has these safety reflectors, which light up when they are illuminated by other vehicles

Comfort lining

  • All LS2 helmets have removable and washable inner lining to keep them fresh and new. Our anatomically designed cheek pads are based on LS2's 3D laser technology for a perfect fit. We use hypoallergenic substances, which remove the moisture to ensure the driver always pleasant conditions

Chin deflector

  • A high-quality fabric insert in the chin area reduces air turbulence in the helmet. The wind deflector is removable, if you want more ventilation in warm temperatures

Automatic sighting system

  • The new mechanism, specially developed for the flip-up helmets, automatically folds up the visor when you lift up the chinrest. Even if you fold back the chin part, the visor raises, so as not to collide with the chin part

Laser cut upholstery

  • Foam with different densities is laser cut in 3D and adapts perfectly to the driver's head shape

Feed ventilation

  • The new LS2 liners are extremely air-permeable and, together with the flow channels in the EPS cushioning, always provide a fresh feeling
