Highlights [Two Optimal Styles] Our heated mittens are available in two versions (on-off type and three-position adjustable temperature type). The switch version has constant temperature, and the temperature-adjustable version has a three-position design. [Ergonomics] Our mittens are ergonomically designed to perfectly fit the lines of your fingers, making them comfortable for you to use without binding your fingers. [High-Quality Material] The mitten fabric is made of high-quality deerskin, which can better resist the cold, and the inside of the mitten is made of coral fleece, which is more comfortable, soft, and warm. [Sensitive Touch Screen Design] The sensitive touch screen design allows you to easily use your mobile phone or tablet without taking off your mittens. You no longer have to worry about freezing your hands when playing on your mobile phone in the cold winter. [After-Sales] If you have any questions, please contact us, our service team will provide you with professional and satisfactory service.
