Know Your Product font by Vic Fieger is a free eroded military display typeface with the grit turned up loud. Chunky, blocky forms are sliced into rough stencil shapes, as if they’ve been sprayed onto a concrete wall and weathered by years of sun and rain. The edges feel chipped and torn, giving headlines a raw, boots-on-the-ground urgency that’s impossible to ignore.
Using Know Your Product instantly adds a rebellious, tactical edge to gig posters, protest graphics, streetwear branding, game titles, underground zines, and bold packaging. This free font works best big and tight, where the broken silhouettes lock together into a solid, shouting wall of ink. For body copy or supporting text, pair it with a clean grotesque sans to let the rugged stenciled letters do the heavy lifting.
