A heavy oblique slab serif with broad, square-cut serifs and flat terminals that keep the letterforms dense and compact. Strokes are consistently thick with restrained modulation, producing a steady rhythm and strong horizontal emphasis. Counters are relatively tight, curves are robust, and joins are simplified, giving the shapes a blocky, engineered feel. Numerals and capitals read particularly solid, with crisp slabs and minimal ornament.
Best suited for display typography such as headlines, posters, ads, and punchy editorial openers where strong texture and impact are desired. It can also work well in sports-themed branding, product packaging, and signage that benefits from sturdy, high-contrast word shapes. For longer text, it’s likely most effective in short bursts—decks, pull quotes, and callouts—where its dense weight remains comfortable to read.
The font conveys a confident, no-nonsense tone with a distinctly retro and sporty flavor. Its weight and forward slant feel energetic and promotional, while the squared slabs add an industrial, workmanlike authority. Overall it reads bold, punchy, and attention-seeking rather than delicate or conversational.
The design appears aimed at delivering maximum impact through thick slabs, simplified geometry, and a forward-leaning stance. It prioritizes bold presence and strong silhouettes, evoking classic advertising and athletic or industrial cues while staying clean and structured.
The oblique angle is pronounced enough to feel dynamic without becoming calligraphic, and the square-ended serifs help maintain clear silhouettes at display sizes. The combination of tight spacing tendencies and heavy strokes suggests it benefits from a bit of breathing room in longer lines.
