This high-performance Lululemon Define Jacket features a sleek, form-fitting silhouette with strategic seam lines for enhanced mobility and sculpted shaping. Crafted from lightweight, breathable Nulu™ or similar soft-touch technical fabric (likely Luon or Nulu blend), it offers 4-way stretch, moisture-wicking properties, and a smooth, brushed interior for comfort against the skin. Key design elements include a full-length front zipper with chin guard, two zippered side pockets for secure storage, thumbholes at the cuffs to keep sleeves in place during movement, and a high mock neck for light coverage and wind resistance. The tonal stitching and minimalist aesthetic align with Lululemon’s signature clean, functional sport-luxe style. Ideal for yoga, Pilates, low-impact training, or as a stylish layer for post-workout errands. Its versatile graphite gray color pairs effortlessly with leggings and athleisure pieces, making it suitable for both studio sessions and casual daily wear. The jacket provides light insulation without bulk—perfect for transitional weather or air-conditioned studios.
