This typeface is built from heavy, squared-off shapes with consistently rounded corners, giving many letters a soft-rectangular (superellipse-like) footprint. Strokes are thick and fairly uniform, with tight internal counters and short apertures; curved letters such as C, G, O, and Q read as rounded rectangles rather than true circles. Terminals are blunt and clean, and the overall rhythm is dense, with wide capitals and compact lowercase forms that keep word shapes squat and solid. Numerals follow the same blocky logic, with closed, rectangular bowls and minimal interior space.
Best suited for punchy headlines, posters, and branding where strong silhouette and mass are desirable. It also fits sports identities, product packaging, and short signage text that benefits from compact, high-impact letterforms.
The overall tone is forceful and utilitarian, combining a machined, engineered feel with a playful softness from the rounded corners. It evokes athletic and industrial signage—confident, loud, and built for impact rather than delicacy.
The design appears aimed at creating maximum visual impact using a rounded-rectangle construction system—mixing strict, engineered geometry with softened corners to stay approachable while remaining unmistakably bold and structural.
Legibility is strongest at display sizes where the tight counters and narrow openings can breathe; at smaller sizes the dense interiors may begin to fill in visually. The lowercase has a distinctly constructed, modular feel (single-story a, compact e), while capitals present as bold, poster-like blocks with consistent corner radii across the set.
