What to know | ARC'TERYX x BEAMS "KOYO" Collection Review: Celebrating 25 Years of Collaboration and BEAMS 50th Anniversary with Fall Foliage Palette
The key details: ARC'TERYX and BEAMS have launched the 6-piece "KOYO" collaborative collection inspired by autumn foliage to celebrate their 25th anniversary of partnership and the 50th anniversary of BEAMS, released on September 25, 2026, at select stores in Japan and multiple countries.
The Fall/Winter 2026 "KOYO" collection, a collaboration between ARC'TERYX and BEAMS, was released simultaneously on September 25, 2026, at BEAMS Harajuku and designated ARC'TERYX brand stores in the United States, United Kingdom, Canada, and China. This launch celebrates the 25th anniversary of their partnership while commemorating the 50th anniversary of the founding of BEAMS. This 6-piece capsule collection takes the aesthetic core of "koyo"—the autumnal phenomenon of Japanese tree leaves turning red—and reimagines technical apparel through street-style design vocabularies.

Design Concept Themed Around "Koyo"
"KOYO" refers to the natural phenomenon of autumn leaves changing color in Japanese. The collection uses this as the starting point for its color story, combining ARC'TERYX's signature "BLAZE" orange-red and "24K" tones with the corporate orange identity of BEAMS, creating rich visual layers through patchwork tailoring.

What Items Does the Collection Include?
This collaboration features a total of 6 items spanning four major categories: outerwear, headwear, apparel, and gear. The highlight is the THETA AR Jacket, whose silhouette design draws from archival details of ARC'TERYX's original 1998 technical jacket. Another piece, the Gamma Jacket, is the first version custom-tailored by BEAMS specifically for this model.
