This high-performance long-sleeve base-layer top features Lululemon’s signature buttery-soft Nulu™ fabric with seamless construction for zero chafing and maximum comfort during movement. The heather gray colorway offers subtle texture, while the ergonomic seam placement and contoured silhouette provide a flattering, second-skin fit. A distinctive curved panel detail across the chest enhances breathability and aesthetic modernity, with thumbholes at the cuffs for added coverage and warmth control. Ideal for yoga, pilates, low-impact training, or as a layering piece under outerwear, it delivers moisture-wicking performance and four-way stretch for unrestricted mobility. The crew neckline is gently ribbed for durability without constriction, and the hem sits comfortably at the hip. Designed for women who prioritize both function and refined minimalism, this top transitions seamlessly from studio to street. Its lightweight, breathable knit makes it perfect for spring and fall wear, and suitable for daily active lifestyles where comfort and elegance intersect.
