This Asics performance long-sleeve base layer is crafted from lightweight, breathable mesh fabric engineered for moisture-wicking and thermal regulation during high-intensity activities. The minimalist white design features a subtle black Asics 'a' logo on the left chest, reflective silver piping along the shoulder seams for enhanced visibility, and a clean crew neckline with black trim for contrast and durability. The slim-fit cut ensures unrestricted movement while reducing drag, making it ideal for running, training, or layering under outerwear. Flatlock seams minimize chafing, and the hem includes a slight drop-tail for coverage during dynamic motion. The garment retains its shape after repeated washes thanks to reinforced stitching and premium synthetic blend construction. Perfect for spring and summer workouts, gym sessions, or as an active layer in transitional weather. Its understated aesthetic also allows for versatile styling beyond sport—pair with joggers or technical pants for athleisure looks. Tag still attached confirms authenticity and new-with-tags condition.
