The Ikon Nova is a lightweight and comfortable climbing and mountaineering helmet that uses hybrid construction to combine the benefits of hardshell helmets with the comfort and protection of in-mold construction. The ABS outer shell features additional molding to make it stronger and more rigid where it integrates with the vent holes and edges. Soft inner padding combines with 18 side and rear vent openings for exceptional comfort and breathability. The ventilation holes are specifically positioned and sized for maximum breathability without compromising protection. The rear dial adjustment system is easy to operate with one hand and tucks into the helmet so it is protected inside the pack. The Ikon Nova has additional space between the adjustment dial and the helmet to be able to accommodate longer hair. The headlamp holder is designed to be able to attach a headlamp without removing the helmet with two ergonomic front clips and a rear elastic keeper.
