This high-performance thermal base layer features a sleek black compression fit with vibrant neon green mesh panels on the side torso and underarm for enhanced breathability and moisture-wicking. The garment includes subtle white geometric graphics on shoulders and chest—diagonal stripes and hexagonal patterns—for modern sporty aesthetics. A ribbed crew neck with lime green inner lining adds comfort and visual contrast. Designed with brushed inner fleece (as emphasized by the '加绒保暖' fire graphic overlay), it provides superior insulation for cold-weather training or layering. The seamless construction and stretch fabric ensure freedom of movement during workouts, running, or outdoor activities. Ideal for autumn/winter fitness routines, gym sessions, or as a mid-layer under jackets. Though no brand logo is visible, the design aligns with generic performance activewear trends—functional, minimalist, and tech-focused without overt branding.
