Marine Layer is a rare apparel brand where both founders still run it, fifteen years and $40M of outside capital later. It's upcycled 1.4 million shirts through its take-back program, though final overseas production still has real labor-risk gaps.
The Big Picture
Marine Layer pairs third-party-verified sustainability with unusual founder continuity: both cofounders still run the company they started, and investors hold only minority positions. The gaps sit overseas, where final production happens in countries with elevated labor risk and living-wage coverage is incomplete. The company answers to its founders, with certifications doing real work and known limits.
