The Lululemon Define Jacket is a premium performance outerwear piece designed for active lifestyles and elevated athleisure wear. Featuring a sleek, form-fitting silhouette with engineered seam lines for enhanced mobility and a flattering shape, this jacket combines technical functionality with minimalist luxury. The full-length front zipper and two side zip pockets are finished with distinctive gold-tone hardware—a signature detail that elevates the otherwise monochromatic black design. Constructed from Lululemon’s proprietary Nulu™ or Luxtreme™ fabric (depending on variant), it offers 4-way stretch, moisture-wicking properties, and a soft, brushed interior for comfort during workouts or daily wear. The high collar provides light wind protection, while the slightly curved hem ensures coverage during movement. Ideal for yoga, running, gym sessions, or as a stylish layer over activewear for errands or coffee runs. Its clean aesthetic, precise tailoring, and premium finish make it a wardrobe staple across seasons—particularly spring, fall, and mild winter days. The jacket’s refined construction and attention to detail reflect Lululemon’s commitment to functional elegance.
