Crafted from high-density 130g neoprene, the outer layer integrates TPU film and functional fibers, boasting exceptional performance. With a low thermal conductivity of only 0.04 W/m·K (far superior to traditional cotton), it effectively blocks cold air infiltration. Featuring a water resistance of over 100kPa, it easily handles light rain and foggy conditions in autumn and winter, preventing inner layers from getting damp. The 130g weight and single-layer design ensure a moderate thickness—sleek enough for outer wear and slim enough for layering under coats, without compromising on wind resistance and durability.
The inner lining is made of high-count combed cotton, offering a soft and gentle touch against the skin with no irritation. Cotton’s moisture-wicking property quickly absorbs sweat from the skin, keeping the interior dry and reducing heat loss caused by dampness. Paired with the outer neoprene, it forms a sealed thermal barrier that locks in heat generated by carbon fiber wires, extending warmth retention. The non-fleece design reduces weight and avoids stuffiness, ensuring all-day comfort even during extended wear—perfect for switching between indoor offices and outdoor activities.
The timeless solid black color uses high-color-fastness dyes, resisting fading after repeated wears. It pairs seamlessly with casual wear, business attire, and sportswear—ideal for daily commutes with shirts/hoodies or outdoor trips with jackets.
The V-neck design flatters the neckline while preventing cold air from entering. Combined with a zipper front, it creates a complete thermal shield when closed, enhancing windproof performance.
Equipped with a high-quality metal zipper, it glides smoothly for quick on/off—more convenient than buttons, especially for rushed outdoor moments. The zipper surface is anti-oxidized to avoid rusting with long-term use.
The lightweight, non-fleece single-layer design allows easy storage: fold it into a compact size to fit in backpacks or suitcases, saving space for travel and camping. The fabric is wrinkle-resistant, regaining shape without ironing after unfolding.
Built with "black gold" carbon fiber wires as the core heating element, it boasts an electrothermal conversion efficiency of over 98%. When powered on, carbon crystal molecules generate heat rapidly through Brownian motion—achieving instant heating in 1-2 seconds and noticeable warmth in 5-10 seconds. Additionally, carbon fiber wires emit 8-15μm far-infrared rays (known as "life-giving rays" in medicine), which resonate with human biomolecules, enhancing cell activity, promoting metabolism, and relieving mild soreness in the neck, shoulders, and lower back. Perfect for office workers, middle-aged and elderly people with cold sensitivity.
Supports 3-speed intelligent temperature adjustment with one-key operation, simple and intuitive:
Low Temperature (≈38℃): White indicator light—warm like autumn sun, suitable for indoor offices and commutes with small temperature differences. Battery life: up to 10 hours.
Medium Temperature (≈45℃): Yellow indicator light—comfortable warmth without overheating, ideal for commutes with large morning/evening temperature gaps and outdoor walks. Battery life: about 6.5 hours.
High Temperature (≈50℃): Red indicator light—powerful cold resistance, effective even in extreme cold of -30℃. Perfect for skiing, fishing, camping, and other outdoor activities. Battery life: about 4.5 hours.
Adopts 5V USB power supply, compatible with most mobile power banks on the market. Simply connect a power bank to the built-in port and store it in the dedicated pocket—enjoy warmth anytime, anywhere without being tied to a fixed power source. Safety is guaranteed by three international certifications (Finland SFS, Denmark DEMKO, Latvia LVS) and multiple protection mechanisms:
Built-in overload protection, short-circuit protection, and temperature fuse—automatically powers off in abnormal situations.
5V working voltage is far below the human safety voltage of 36V, eliminating electric shock risks. The heating element passes over 10,000 bending tests for long-lasting durability.
IPX4 water-resistant interface: seal the port before cleaning. Supports hand washing or machine washing in a laundry bag.
Daily Commuters: Tackle morning/evening temperature changes without bulky coats—balance warmth and style.
Outdoor Enthusiasts: Ideal for skiing, hiking, fishing, camping—powerful cold resistance and portable design.
Middle-Aged & Elderly: Relieve cold sensitivity and mild neck/shoulder pain with warmth and far-infrared therapy.
Office Workers: Alleviate sedentary soreness and stay warm for improved work efficiency.
Before cleaning, disconnect the USB cable and seal the port cover. Avoid washing while powered on or soaking for a long time.
Only use compliant 5V mobile power banks. Do not use high-voltage power sources to prevent short circuits.
Disconnect power when not in use. Store in a dry, ventilated place—avoid direct sunlight or contact with sharp objects.
