This high-performance long-sleeve base-layer top features Lululemon’s signature buttery-soft Nulu™ fabric with strategic mesh panels for enhanced breathability and moisture-wicking. The ergonomic seam placement and seamless construction ensure zero chafing during movement, while the contoured silhouette offers flattering support without compression. A distinctive ribbed hem and thumbholes at the cuffs provide functional detail and secure fit. The heather gray colorway combines subtle tonal texture with modern minimalism, ideal for layering or solo wear. Designed for yoga, Pilates, light training, or everyday active living, this top delivers exceptional comfort and stretch recovery. Its lightweight, four-way stretch fabric moves with the body, maintaining shape wash after wash. The scoop neckline is modest yet flattering, and the back yoke features a reinforced mesh panel for ventilation during elevated heart rates. Perfect for transitional seasons or indoor workouts, it pairs effortlessly with leggings or joggers for a cohesive athleisure look.
