This techo cover was created in collaboration with Natal Design, an apparel brand that interprets art and culture through a unique lens, translating that vision into clothing, camping gear, and more through thoughtful design and details.
The Cousin-size cover is a tri-fold style made from Natal Design’s original “Retro Stripe” fabric. The vibrant, vintage-feeling stripe pattern is one of the brand’s signature designs. Durable, stain-resistant 1000D nylon fabric and deeply colored piping work together to snugly envelop and protect your techo. A name tag on the front and matte-finish snap buttons add distinctive accents to the design. 
Because each cover is cut from a single large piece of fabric, the placement of the pattern will vary from piece to piece. We hope you’ll treasure it as a one-of-a-kind encounter.
The inside of the cover has a sophisticated look, featuring a burgundy PU base. The Natal Design logo is foil-pressed at the center, accompanied by a message that captures the brand’s philosophy. The fabric visible in the background features a vibrant print of the iconic “Lucky Swallow” motif. This all-over pattern of swallows, believed to bring good fortune, continues seamlessly underneath the pocket.

The Natal Design lineup also includes a Small Drawer Pouch alongside the techos. See the full Natal Design series here.
