The Intelligent 3-in-1 Unisex Heated Jacket System is designed as a next-generation smart wearable, combining modular apparel design with precision thermal control technology. The outer shell integrates RECCO Rescue Technology, enhancing searchability in emergency situations, while the inner heated layer features five independently controlled heating zones engineered for adaptive warmth and personalized comfort. Each heating zone can be adjusted independently, allowing users to regulate heat distribution based on activity level, environment, and personal preference. The system supports an adjustable temperature range from 35°C to 45°C, delivering consistent and responsive warmth across changing conditions. Designed with modular intelligence, the inner jacket includes detachable sleeves, enabling seamless conversion between a full heated jacket and a lightweight heated vest. This flexibility allows the system to function across multiple scenarios, from outdoor sports and travel to daily urban commuting. Built for adult users and suitable for all genders, this intelligent jacket system represents a practical evolution of smart wearable technology—where functionality, safety, and thermal performance work together in a single adaptive design.
