A heavy, block-built sans with rounded-rectangle construction and softened corners throughout. Strokes are monolinear and strongly geometric, with broad horizontal proportions and tight internal counters that read as small cut-ins rather than open bowls in several letters. Curves are expressed as superellipse-like rounds, while joins and terminals stay flat and orthogonal, producing a crisp, engineered silhouette. Spacing and widths vary by glyph, but the overall rhythm remains dense and punchy, emphasizing mass and clear silhouette over fine detail.
Best suited to display settings where impact matters: headlines, poster typography, sports and team-style branding, packaging front panels, and bold title treatments. It can also work for short UI labels or signage when set large, where the compact counters remain clear and the sturdy shapes maintain legibility.
The tone is bold and no-nonsense, with a rugged, industrial feel that also nods to retro athletic and arcade-era display typography. Its chunky shapes and squared rounds convey strength, utility, and immediacy, making text feel assertive and attention-forward.
The design appears intended to deliver maximum visual weight with a geometric, rounded-rectangular language—prioritizing silhouette clarity, compactness, and a tough, engineered personality for branding and large-scale display use.
Distinctive rectangular counters and notch-like apertures give many letters a cut-out, almost stencil-adjacent character, especially in closed forms and numerals. The lowercase is built with similarly blocky forms and a tall presence, helping it hold its own in short words and headlines. The font’s strong black density benefits from generous size and contrast against the background, where its rounded corners prevent the forms from feeling overly sharp.
