New Zealand-based sustainable fashion brand Untouched World has released its Spring/Summer 2026 collection, building on its partnership with Spiber into a second season featuring Brewed Protein™ fiber.

Following last year’s initial release, Untouched World has carried over three core styles from the previous season—the Fountain Sweater, Maelyn Tee, and Arlee Singlet. Each piece is crafted from a blended fabric of 90% organic cotton and 10% Brewed Protein™ fiber, combining the familiar comfort of cotton with the soft, gentle hand feel of Spiber’s next-generation protein material.

Arlee Singlet – A soft, close-fitting singlet with a high round neck and hip-length hem, designed as an easy summer layer.

Fountain Sweater – A statement striped crew-neck sweater combining timeless design with the extraordinary softness of a 90% organic cotton and 10% Brewed Protein™ blend.

Maelyn Tee – A perfectly proportioned T-shirt with a classic crew neckline and elbow-length sleeves, balancing relaxed comfort with refined, versatile style.

Carrying these favorite designs forward into a second season builds on the collaboration between Untouched World and Spiber  , and continues the exploration of Brewed Protein™ fiber in everyday wardrobe staples.
