A heavy, block-built sans with rounded-rectangle (superellipse) contours and large, squared counters. Stroke terminals are mostly flat and orthogonal, with softened corners that keep the shapes from feeling sharp. Proportions are generally broad, with tight apertures and enclosed bowls that read like cut-outs; many letters show small notches and inset corners that create a slightly stencil-like, engineered feel. Uppercase forms are compact and uniform, while lowercase keeps a simple, robust structure with chunky stems and minimal modulation, emphasizing mass and stability.
Best suited to bold headlines, posters, and branding where a strong, compact word shape is desired. It also fits signage, labels, and packaging that benefit from an industrial or athletic voice, especially in short phrases and all-caps settings.
The overall tone is forceful and utilitarian, evoking industrial labeling, athletic branding, and rugged equipment graphics. Its rounded-square geometry gives it a retro-tech flavor—confident and no-nonsense rather than friendly or delicate.
The design appears intended to deliver maximum impact through dense, rounded-rectangular forms and consistent, engineered detailing. By pairing soft corners with hard, orthogonal structure and punched counters, it aims to feel tough, modern, and immediately attention-grabbing.
The numerals and caps share the same squared, punched-counter logic, which helps headings look cohesive and impactful. The tight inner spaces and dense ink coverage suggest it will read best when given enough size or tracking to keep counters from visually closing in.
