Why Frii Wilii Was Created

Frii Wilii was born out of frustration with uncomfortable, restrictive underwear that just didn’t work for real life.

Michael, our founder, was tired of the “shriveled up” feeling and constant adjustments that came with traditional briefs and boxer briefs—no matter the brand. He wanted something better, not just for himself, but for every guy who’s ever felt let down by their underwear.
