HISTORY
Introduced in the late 1990s, the Theta AR (“All Round”) jacket was one of Arc’teryx’s defining outerwear models, showcasing the brand’s early mastery of technical construction and waterproof-breathable fabrics. This 1998 archive version, featuring the rare gold phoenix logo at chest, is built from Gore-Tex and reflects the brand’s pioneering use of seam-sealed waterproofing and ergonomic patterning, setting a new standard for alpine and backcountry apparel.
