A heavy, geometric sans with rounded-rectangle (superellipse) construction and broadly uniform stroke thickness. Corners are softened but remain decisively squared, giving counters and bowls a rectangular feel (notably in O/0, D, P, and B). Terminals are mostly flat and blunt, with occasional small notches and inset joins that read like subtle ink-trap-style cut-ins at tight interior corners. The lowercase is compact and sturdy, with a single-storey a and g, short-to-minimal ascenders, and a generally dense rhythm that prioritizes mass and solidity over openness.
Best suited to display settings where maximum presence is needed: headlines, posters, sports and team branding, packaging, and bold signage. It can work for short bursts of text at larger sizes, but its dense counters and compact rhythm make it less comfortable for long-form reading.
The overall tone is forceful and confident, projecting a utilitarian, high-impact voice. Its squared curves and dense texture suggest an athletic, machinery-like energy that can feel both retro and contemporary depending on color and layout.
The design appears intended to deliver a bold, highly legible display voice built from squared, rounded geometry, optimizing for impact and reproducible shapes in branding and signage. The small interior cut-ins and blunt terminals reinforce clarity at joins while maintaining a rugged, engineered character.
Counters are relatively tight for the weight, and the font’s squared interior shapes create a strong, poster-like texture in paragraphs. Numerals are built with the same rounded-rect geometry, with particularly prominent, blocky forms in 8 and 9.
