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 design for added coverage. The fabric exhibits a fine textured weave visible in close-up, indicating advanced synthetic construction (likely polyester-spandex blend) for stretch and recovery. Tag still attached confirms authenticity and new-with-tags condition. Perfect for spring/summer athletic wear or as a technical layer in transitional seasons. Suitable for daily sporty casual wear, gym sessions, or outdoor endurance activities where comfort and performance are prioritized.
