2 customer reviews



314.05It all starts with a KISS! 
Bringing innovation and precision engineering to full-face helmet design, Square One presents the KISS. A multi-discipline, state-of-the-art, high-performance helmet, the KISS features a 2mm thick polycarbonate lens with full mouth exposure, panoramic visibility and Square One’s NEW patent-pending anti-fog ventilation system. Whether your aerial pleasures find you belly-to-earth or head-down, this unique vent system will greatly reduce fogging in all conditions. 
The KISS also features a NEW Quick-Tight Latch Closure System utilizing two levers to tighten or loosen the helmet on the user’s head. Simply pop the levers closed prior to exit and your helmet is secure!
Square One went one step further and integrated dual audible altimeter pockets with exterior access. Dual pockets allow for critical instrument redundancy and exterior windows simplify the motions of accessing your instruments to set altitudes, recall information, or simply power the device off and on. 
These technologies combined with our proven Quick Change Lens System render the KISS the most advanced helmet in skydiving today.
