Quality heated base layers from reputable brands have multiple safety features including overheat protection, short-circuit protection, and automatic shutoff. The heating elements typically max out at 130°F (54°C), which is warm but not burn-inducing against the skin. Always follow the manufacturer's instructions and stop using the garment if you notice any unusual heat, smell, or malfunction.
