OGK is a well-known helmet brand from Japan, its main products include motorcycle helmets and cycling helmets, compared to cycling helmets, OGK's motorcycle helmets are more well-known, and can be seen in the world's top motorcycle competition MotoGP.
 
In the field of cycling helmets, OGK Kabuto has always been known for its workmanship and comfort. The Asian head type belongs to the round high head type (round), while the European and American head shape is flat, which belongs to the medium and high head type (oval), because the OGK brand is derived from Japan, its main market is located in Asia, so the sides of the helmet are wider, and for Asians, the OGK helmet is more comfortable to wear.
 
Traditional aerodynamic helmets often pursue good aerodynamic effects at the expense of air permeability, reducing the comfort of the rider, OGK helmets use CFD (Computational Fluid Dynamics) computational fluid dynamics design, which improves the breathability of the helmet on the premise of maintaining the fluid dynamics shape of the helmet.
 
In terms of helmet appearance, the OGK helmet boldly adopts an angular design, and the angular helmet has higher longitudinal structural strength, which can more effectively disperse the impact force. In addition to this, the angular design also acts as a guide to the air to the top of the vents, taking away the heat from the head.
 
OGK helmet products can be roughly divided into three categories: Cycling, Aero helmet, and Schoolmet. The Aero helmet series is built with aerodynamics in mind for speed. The Schoolmet helmet has a smaller head circumference and is designed for students who commute by bike. Cycling is a series for cycling enthusiasts.
 
There are many types of helmets in the Cycling series, and different models vary in helmet shape, number of vents, and helmet weight. The ALFE, REGAS-2, REZZA and FM-8 have a detachable brim for mountain biking. The FLAIR weighs only 170g (size S/M), and its lightweight helmet is its biggest selling point. The main feature of the ARS-3 is eye protection, users can choose various protective shields on the helmet, different colors of protective shields have different visible light transmittance, with the effect of blocking wind, sand and sun.
