Prozak by studio Kmzero is a free condensed sans serif with a dry, urban tone. The letters feel tall and tightly packed, mixing blunt vertical strokes with soft rounded turns that keep the font from going mechanical, and that slim rhythm gives it a slightly poster-like pull.
It fits music flyers, streetwear branding, magazine cover lines, title cards, and compact logotypes where you want height without ornament. As a free font, Prozak works best in short display settings, especially stacked words and narrow headers, because the letters hold a strong vertical beat while the rounded shapes stop the look from turning cold.
