Ergonomic Layout

Our team is aiming to bring a mechanical keyboard that helps you improve the posture, maximizes comfort, and eliminate muscle strain. Designed for long sessions of typing, the AB Red Hat GS66 is born to solve the issue. It features a unique layout design - AB Red Hat - to allow the palms, wrists, and arms to stay in a natural and relaxing position while fingers can quickly access fully customizable macro functions with ease for a more intuitive workflow. 

Durable GK1-Cherry PBT Keycaps

We choose to go with the innovative ergonomic GK1-Cherry keycap profile with the top-grade PBT thermal sublimation keycaps. The ideas behind the GK1-Cherry design is ergonomics and aesthetics. The shapes of keycaps are specifically designed as spherical forms to reduce the stress on fingers and hands. By doing so, you can enjoy a more ergonomic and comfortable typing experience, with a smooth curvature that perfectly fits the shape of each finger.
