Marine Layer is a San Francisco-based casual apparel brand built around one obsession: absurdly soft clothes. Founded in 2009 by Mike Natenshon and Adam Lynch, the company built its identity on proprietary fabrics - blends of Supima cotton, MicroModal spun from beechwood pulp, and recycled fibers - sold through a direct-to-consumer model spanning e-commerce and 55+ retail stores. A Certified B Corporation, Marine Layer runs a textile take-back program called Re-Spun that has collected over a million used T-shirts and turns them into new garments. The brand sits in the premium-casual, California-lifestyle segment, competing on comfort, sustainability credentials, and a laid-back aesthetic.
Stitch Fix is an online personal styling service that pairs data science and machine learning with human stylists to send clients hand-picked apparel, shoes and accessories. Clients complete a Style Profile, receive a curated shipment (a "Fix") to try on at home, keep what they like and return the rest, or shop directly through the on-demand Freestyle storefront. Founded in 2011 by Katrina Lake and public since 2017, the San Francisco company serves millions of clients across the US and UK and reported roughly $1.27 billion in fiscal 2025 net revenue.
