  • With 21 optimized vents, the AirEvac ventilation system allows goggles and helmet to function as a system, venting warm, moist air away from the goggles—and away from the head
  • Koroyd provides superior impact absorption, design flexibility and ventilation when compared to materials traditionally used in helmet construction
  • Utilizing crumple-zone cylinders that crush uniformly on impact, Koroyd manages energy more efficiently with less volume than traditional protection materials
  • Rotational motion can cause brain injuries; with MIPS, a low-friction layer slides 10 to 15mm in all directions, reducing rotational motion to the brain during impact
  • Unique pad kit includes 3 sets of sized cheekpads, 2 sets of sized crown liners and 2 neck rolls to ensure a proper fit̵all of which can easily be removed for cleaning
  • Pads are made from Hybrid X-Static/XT2 for antibacterial performance
