This high-tech heated jacket features 23 precisely mapped heating zones across the torso, shoulders, arms, and hood for comprehensive warmth distribution. Equipped with four independent control switches (as highlighted in the image), users can customize heat intensity per zone—ideal for outdoor activities in cold environments. The quilted black outer shell appears wind-resistant and water-repellent, while internal heating elements glow orange/yellow in visualization to indicate active zones. A compact battery pack (likely USB-powered or rechargeable) is integrated near the chest, with a small control panel visible on the left chest area. Designed for practicality and comfort, it maintains a sleek puffer-jacket silhouette without bulk, suitable for commuting, hiking, winter sports, or daily wear in sub-zero conditions. The ergonomic layout ensures heat reaches core areas (chest, back, kidneys) and extremities (arms, neck), preventing cold spots. Though no brand logo is visible, the technical specification ('23区发热', '四个开关') suggests a specialized functional apparel product from a Chinese techwear or outdoor gear manufacturer. Not a fashion-first item but engineered for thermal performance and user-controlled adaptability.
