San Francisco-based Marine Layer (asi/68730), supplier of casual lifestyle apparel items, has received a significant minority investment from Provenance, a Los Angeles-based growth equity investment firm, which will now also join Marine Layer’s Board of Directors.

Mike Natenshon, founder/CEO of Marine Layer.

“We’re excited to partner with Provenance,” said Mike Natenshon, CEO and founder of Marine Layer, in a statement. “They have a strong track record of performance, and they really understand our business and brand, which is huge for us. I look forward to working closely with Provenance to take Marine Layer to the next level.”

Founded in 2010, Marine Layer currently has almost 40 stores across the United States with plans for continued expansion.

“Mike Natenshon and the Marine Layer team have created an outstanding lifestyle brand that has transcended its foundation built on the ‘absurdly soft’ tee shirt,” said Anthony Choe, founder of Provenance, in a statement. “We’re proud to partner with the company to replicate their success in other markets throughout the country, as well as help them grow their direct-to-consumer business.”
