Features:

1. Electric Heater Keeps You Warm: The ROCKBROS cycling balaclava features a multi-layered thermal design with an outer layer of windproof fabric that is durable enough to withstand the cold, a middle layer with high-quality carbon fiber heating technology, and an inner layer that traps the heat. The balaclava's smart design ensures the heating area covers both the ears and chest, providing continuous and efficient warmth.

2. Three-Level Setting: Easy to use, simply press the button for two seconds to turn the heating on or off. A short press of the button cycles through the three modes: Low (approx. 40°C), Medium (approx. 50°C), and High (approx. 60°C). The heated balaclava requires a 5V 2A charger. The heating time is up to 2.5 hours (high temperature) and up to 7 hours (low temperature). (This product does not include a power bank. You must bring your own rechargeable power bank.) 3. Mask Design: The mask section of the ski mask features a special three-layer design consisting of a mesh, an activated carbon filter, and a polyester mesh. The activated carbon filter in the middle is replaceable, effectively filters dust from the air, and provides a safer and more hygienic environment for use. 4. Compatibility: The warm balaclava is well-cut and fits snugly on the head. It is suitable for motorcycle, bicycle, ski helmets, etc. The USB power connection is compatible with various types of chargers, convenient and practical. 5. Detailed Care: • Specially designed for glasses wearers: Eyeglass holes on both sides of the headgear ensure clear vision. • The front of the winter mask is equipped with a convenient storage pocket for mobile phones and other small items. • For riders with long hair, a specially designed hair port allows for a ponytail to be threaded through.
