Seoul-based knitwear brand JUUKIFF will introduce two WHOLEGARMENT knit pieces crafted from a blended yarn incorporating Brewed Protein™ fiber, available from mid-February 2026.

The collection features a yarn that combines Brewed Protein™ fiber—known for its fine, smooth surface—with cotton. The distinctive texture of the protein-based fiber is complemented by the gentle touch of cotton, creating a soft, enveloping feel and everyday comfort.

To honor the material’s natural character, the yarn is intentionally left undyed. This approach preserves its inherent color and texture, allowing JUUKIFF’s design philosophy, “A Structured Intimacy”—a balance between structure and softness—to be expressed through this collection.

We are truly honored that our circular approach and long-term commitment to responsible material development have resonated with JUUKIFF, leading to the continued adoption of our materials in the Spring/Summer 2026 collection, following Spring/Summer 2025.
