This high-performance thermal compression set features a long-sleeve base-layer top and matching full-length leggings, engineered for cold-weather athletic activity. The top showcases ergonomic mesh ventilation panels across shoulders, chest, and side torso for breathability, while the ribbed V-neck and seamless construction ensure comfort during movement. Both pieces are labeled '加绒 保暖' (fleece-lined, warm) with flame graphics—indicating internal fleece lining for enhanced insulation without bulk. The leggings feature a wide elastic waistband with 'COMBAT PRO CO' branding, flatlock seams to prevent chafing, and targeted compression zones for muscle support and circulation. Made from stretchy, moisture-wicking synthetic blend (likely polyester/spandex), the set dries quickly and retains shape after repeated use. Ideal for winter workouts, outdoor training, layering under sportswear, or as thermal underwear in sub-10°C conditions. The sleek black design with subtle gray tonal patterns offers a modern, tactical aesthetic suitable for gym, running, hiking, or casual athleisure wear. Notable for its functional minimalism and performance focus—no logos beyond waistband text, emphasizing utility over branding.
