The Lululemon Define Jacket is a premium performance outerwear piece designed for active lifestyles and elevated athleisure wear. Crafted from signature Nulu™ fabric—soft, stretchy, and sweat-wicking—it offers exceptional comfort and mobility. This black version features distinctive gold-tone metal zippers on the full-length front closure and two vertical side pockets, adding a luxe contrast to the minimalist silhouette. The jacket has a sleek, tailored fit with articulated seams for ergonomic movement, a high mock neck for light coverage, and ribbed cuffs and hem for a secure, polished finish. Ideal for yoga, studio workouts, or transitional layering in spring/fall, it transitions effortlessly from gym to street. Its lightweight construction (approx. 280g) ensures breathability without bulk, while the smooth texture resists pilling and maintains shape after repeated wear. Perfect for daily wear, casual outings, or travel—combines technical functionality with refined design aesthetics.
