Sierra Supply Co

Sierra Supply Co. is a San Francisco leather goods brand built around small-batch production and hands-on craftsmanship. Its pieces are cut, stitched, and finished by hand in a workshop run by two makers, with each item described as one of a kind.

The collection includes card holders, four-pocket folds, wedges, envelopes, passport covers, journals, and accessories, offered in vegetable-tanned leather and shell cordovan. Materials and construction are central to the brand’s approach: its leather is bark-tanned and selected from established tanneries, designed to darken, soften, and develop a deeper shine with age. Products also use solid brass snaps, rivets, and rings, which gain patina through regular use, along with American-made waxed cord and hand-sewn saddle stitching.

Sierra Supply Co. releases goods in numbered batches, with individual pieces presented in distinctive colors and finishes, including marbled shell cordovan. Customers can browse the full collection online and find information about materials and care, contact details, and updates through the brand’s email newsletter and social media
