Under Armour HeatGear Half-Zip Base Layer in sleek black—engineered for high-performance training with moisture-wicking, lightweight fabric and strategic ventilation. Features a quarter-zip closure for adjustable airflow, flatlock seams to prevent chafing, and reflective piping on shoulders for visibility. The iconic silver UA logo on chest and left thigh adds subtle branding. Designed for optimal thermoregulation during intense workouts, this base layer offers compression support without restricting movement. Ideal for gym sessions, running, or layering under outerwear in cooler conditions. Fabric blend (typically 84% polyester, 16% elastane) ensures stretch recovery and odor resistance via antimicrobial treatment. Seamless underarm gussets enhance mobility, while the ribbed cuffs and hem provide a secure, non-slip fit. Perfect for men seeking functional sportswear that transitions seamlessly from training to casual wear. Highly versatile across seasons—worn alone in mild weather or as a mid-layer in fall/winter. Built for durability and comfort, it maintains shape wash after wash.
