I purchased this last month. I've used it about 3 times, but the size doesn't quite fit, so I'm putting it up for sale. The temperature is sufficiently warm at level 1 (45°C). The thin design allows it to be used as an inner glove. How about pairing it with your favorite outer gloves? Charging is via type C. A convenient Y-shaped cable for charging is included. I think it's convenient that you can charge it without removing the battery. These are smart gloves with a heating function. - Color: Black - Function: With heating function - Material: Synthetic fiber - Features: Smart design - Size: Free size Thank you for looking.
