A heavy, block-constructed sans with rounded-rectangle geometry and tightly controlled internal spaces. Strokes stay uniform and straight-sided, while corners are softened into superelliptical curves, producing squared bowls and rectangular counters (notably in O, D, P, and 0). Many joins and terminals are cut with flat, horizontal or vertical endings, and several glyphs show small notches or separated segments that read as purposeful cut-ins rather than organic curves. Lowercase forms are compact with a tall x-height and short extenders, keeping a dense, poster-like texture in text.
Best suited to display settings such as headlines, posters, packaging, and identity work where impact and a compact, blocky texture are desirable. It also fits sporty or industrial-themed graphics and bold UI or signage moments where brief labels need to stand out.
The overall tone is forceful and functional, with a contemporary industrial feel and a hint of retro signage. Its squared, rounded-corner shapes and tight counters create a rugged, engineered voice that suggests equipment labels, sports branding, or bold editorial titling.
The design appears intended to translate rounded-rectangle construction into an emphatic display sans, prioritizing visual solidity and consistent, engineered shapes over airy readability. Its tight counters and cut-in details reinforce a rugged, utilitarian personality aimed at high-impact typography.
In running text, the typeface maintains strong rhythm through repeated rounded-rectangle motifs, but the narrow apertures and compressed counters make it most comfortable at larger sizes. Numerals match the letterforms’ squared construction, and punctuation shows the same chunky, simplified styling.
