A geometric sans built from squared, rounded-corner outlines, with a uniform stroke and softened terminals throughout. Counters and bowls tend toward rounded rectangles, producing a consistent superellipse rhythm across caps, lowercase, and figures. Curves are minimized in favor of straight segments and broad radii, giving letters a compact, engineered feel; diagonals stay crisp while joins remain smooth. The lowercase is simple and utilitarian, with single-storey forms and short, blocky extenders that preserve a tight, even texture in text.

Best suited to high-impact headlines, logotypes, and branding where a techno-geometric voice is desired. It also works well for UI labels, wayfinding, and product markings that benefit from robust, simplified shapes and strong silhouette clarity at medium-to-large sizes.

The overall tone is modern and technical, evoking interfaces, machinery, and contemporary sports branding. Its rounded-square geometry reads confident and functional rather than friendly or calligraphic, with a forward-looking, sci‑fi edge.

The design appears intended to deliver a contemporary, engineered aesthetic by unifying letter construction around rounded rectangles and consistent, smooth terminals. It prioritizes strong shapes and a steady rhythm for bold display typography in modern digital and industrial contexts.

Openings are generally controlled and slightly narrow, which strengthens the monolithic silhouette and helps maintain a uniform color in display settings. Numerals follow the same rounded-rectangular logic, reinforcing a cohesive, system-like appearance across alphanumerics.
