Core Functions：
● Heating Function: Delivers gentle heat quickly and evenly via built-in carbon fiber heating wires or red-light heating beads. It can improve poor local blood circulation from prolonged sitting, joint coldness in autumn and winter, and muscle stiffness caused by strain, while relieving soreness from fatigue, cold-dampness or inflammation. Suitable for daily maintenance, post-operative care and relaxation during work breaks.
● Protective Support: Provides gentle support for joints (such as neck, elbows, waist and back) or muscles, reducing the risk of sports injuries. Also suitable for body protection during daily activities.
Design Features: Secured with Velcro for easy putting on and taking off, and adjustable tightness to fit users of different body types. The fabric balances breathability and warmth retention, preventing stuffiness during long-term wear.
● Applicable Population: People in need of warmth, outdoor sports enthusiasts (e.g., mountaineering, tennis, etc.), and those fatigued from long-term desk work.
