■Product Overview Engineered by the world-renowned Japanese sports giant "MIZUNO," this high-performance running beanie (knit cap) features intelligent moisture-absorbing thermal technology tailored for elite winter performance. The cornerstone of this headwear is MIZUNO's proprietary "BREATH THERMO" fabric, a revolutionary textile that captures moisture released by the body and chemically transforms it into comfortable heat. Perfect for freezing early morning sessions, late-night jogs, or high-intensity outdoor winter sports, it completely insulates your head from icy wind chills while regulating moisture. The sleek and professional "09: Black" colorways seamlessly integrate with any sportswear collection. Its low-profile, minimalist aerodynamic aesthetic makes it an absolute must-have gear piece trusted by dedicated athletes across the globe.

■Key Features & Details - 【Revolutionary BREATH THERMO Heat Tech】: Absorbs microscopic body vapors to actively generate heat, resulting in high insulation while preventing inner moisture buildup to keep you completely dry. - 【High-Visibility Retroreflective Prints】: Integrated with prominent reflective detailing on the sides and rear. It dramatically boosts early morning or nighttime safety on dark suburban roads. - 【Aero-Fit Low-Profile Silhouette】: Designed with a precise, multi-panel flat-seam construction that prevents bulkiness, providing a tight, aerodynamic fit that eliminates shifting or wind resistance during rapid runs. - 【Superior Elasticity & Secure Hold】: Infused with 10% Polyurethane for multi-directional stretch. It offers a snug yet stress-free compression fit that stays locked in place even through rigorous, high-speed motions.

■Material & Care Instructions - Material Composition: 84% Polyester, 10% Polyurethane, 6% Synthetic Fiber (Breath Thermo) - Fabric Features: Active heat generation, high thermal retention, 4-way stretch, ultra-lightweight, quick-dry moisture management. - Care Instructions: Machine washable (use of a mesh laundry bag and a gentle cycle is highly recommended).
