The Reef Keeper Cap (Blue) — Vault Diffusion Line
For the ones who chase waves and stories.
Part of the Vault Diffusion Line, the FRNKLN VAULT Surf Cap captures the laid-back rhythm of the coast — crafted for days spent under the sun, near the water, or wherever life flows free. Made in partnership with one of our trusted Diffusion manufacturers, this cap combines effortless design with eco-conscious innovation.
Constructed from 100% recycled nylon, it’s lightweight, quick-drying, and built for movement — perfect for beach adventures, sunset drives, or casual weekends. The unstructured snapback fit delivers relaxed comfort, while the FRNKLN VAULT surf logo brings that vintage-meets-modern vibe that defines the Diffusion range.
While FRNKLN VAULT will always be a cap company, this piece shows how far a single story can travel — from the city to the sand.
Born in Los Angeles. Styled for the coast. Part of the Vault.
