Arc’teryx and BEAMS are marking 25 years of collaboration with a six-piece anniversary collection that reconnects their technical-outdoor partnership to one of its defining early silhouettes. The centerpiece is the Theta AR Jacket, a revival of the 1998 shell updated in a Koyo palette inspired by Japanese autumn foliage.

The Arc’teryx shell uses GORE-TEX PRO ePE and retains period details including a center storm flap, covered pocket zippers, and oversized pull tabs. Blaze, BEAMS orange, 24K yellow, and deeper seasonal tones turn the familiar technical shell into the collection’s most overt expression of BEAMS’ color-blocking language.

The rest of the capsule broadens the idea into a wearable system. A Gamma softshell marks the first BEAMS special-order version of that jacket, while relaxed Jogen cargo pants use a lightweight cotton-nylon blend. A 240gsm long-sleeve jersey references six past anniversary products, and the Konseal 15 backpack uses Arc’teryx’s abrasion-resistant 315-denier Hadron fabric. A Gamma five-panel cap completes the lineup.

The release extends a collaboration previously explored through projects such as the Arro Capsule Collection, but the anniversary framing gives the archival references more purpose than a routine seasonal recolor.

The collection launches September 25 through BEAMS and participating Arc’teryx stores in the U.S., U.K., Canada, China, and Japan.
