Spiber’s Brewed Protein™ fiber has been selected for “john masters UNITED ARROWS,” a new brand launching for the Fall/Winter 2026 season through a collaboration between UNITED ARROWS and john masters organics.

Built around the concept of “choosing comfort through the senses of the skin,” the brand offers products designed to respond to the skin and the senses. For its first-season collection, a towel featuring Brewed Protein™ fiber was developed with a focus on the fiber’s soft, moist hand feel.

With Brewed Protein™ fiber used in the pile, the towel offers a soft, voluminous feel and a smooth touch against the skin. It is an everyday item that allows users to experience the distinctive texture of Brewed Protein™ fiber in their daily lives.

We are pleased to be part of the launch of this new brand through our material.

Spiber will continue to explore new possibilities of Brewed Protein™ fiber through collaboration with a diverse range of partners.
