Sustainable surf-rooted apparel from 11-time world champion Kelly Slater anchors the Outerknown store in Carlsbad's Forum shopping center on Calle Barcelona. Co-founded in 2015 with designer John Moore, the Fair Labor Association-accredited brand uses over 90% organic, recycled, or regenerated materials — a fiber-transparency commitment that aligns with the locally shaped board ethos at Degree 33 Surfboards. The Carlsbad store carries the signature Blanket Shirt with corozo-nut buttons, S.E.A. Jeans in organic stretch denim, and Hightide board shorts alongside the women's resort line launched in 2019. Calle Barcelona positioning puts the storefront in Carlsbad's La Costa corridor off El Camino Real, within miles of the Carlsbad State Beach breaks that shaped the brand's coastal identity. Regenerative Organic Certified cotton anchors the brand's tee and basics program through a fully traceable seed-to-garment supply chain — an ingredient-level sourcing model that appeals to the same values-driven shoppers frequenting The Drydown fragrance studio in Carlsbad Village. The signature Blanket Shirt uses heavyweight organic-cotton flannel at 10 oz per yard with corozo-nut buttons harvested from South American tagua palms, a fully biodegradable hardware detail replacing conventional petroleum-based plastic closures.
