A heavy, geometric sans with rounded-rectangle construction and softened corners throughout. Curves resolve into squarish bowls (notably in O, Q, and 0), while straight strokes stay thick and uniform, producing a dense, high-ink silhouette. Terminals are mostly flat, counters are relatively small, and several joins and diagonals are cut with crisp, angular facets that add a slightly mechanical rhythm. The lowercase is sturdy and compact, with simplified forms and minimal modulation; figures are similarly chunky, with a particularly square, inset feel to 0/8/9 and a strong, blocky 4/7.
Best suited to headlines, posters, and short emphatic copy where its dense forms and squared rounds read as intentional graphic texture. It also fits sports identity work, product packaging, and signage that benefits from a compact, high-impact presence.
The overall tone is bold and no-nonsense, with a sporty, industrial energy. Its rounded-square geometry evokes retro signage and athletic branding, feeling confident and loud rather than delicate or literary.
The font appears intended as a robust display sans that merges rounded-rectangle geometry with blunt, engineered detailing to maximize punch and recognizability in branding and titling.
The design leans on squarish apertures and tight counters, which strengthens impact at display sizes but can make internal spaces feel compressed in longer text. Angular cut-ins and notches in several letters add a subtle engineered/stenciled character without becoming decorative.
