A compact, condensed sans with heavy, uniform strokes and rounded-rectangle (superellipse) construction throughout. Curves are tightened and squared-off, with broad, flat terminals and minimal modulation, giving counters a rounded, rectangular feel. The x-height reads tall and the lowercase is dense and space-efficient, while capitals maintain a firm, vertical stance. Overall spacing appears tight but controlled, producing a strong, continuous dark rhythm in text and an especially solid silhouette in display sizes.
Best suited to large-scale use where dense color and compact width are advantageous: posters, headlines, storefront and wayfinding signage, packaging panels, and bold brand marks. It can also work for short subheads or callouts where maximum emphasis is needed without consuming much horizontal space.
The tone is forceful and no-nonsense, with an industrial, poster-forward attitude. Its compressed proportions and hefty weight convey urgency and impact, evoking sports, workwear, and headline typography with a slightly retro, utilitarian edge.
The design appears intended to deliver maximum impact in minimal width, using superelliptical geometry and heavy, even strokes to create a tough, modern display voice. Its tall lowercase and compact rhythm suggest an emphasis on legibility at display sizes while maintaining a strong, uniform texture in short text runs.
Round glyphs like O/C/G lean toward squared curves rather than true circles, reinforcing a mechanical, engineered character. Numerals and capitals share the same blocky logic, helping mixed alphanumeric settings feel cohesive and punchy.
