Protect your legs from frostbite this winter with cordless leg warmers. Using the design of traditional leg warmers, Japanese company Yamazen inserted a special warming system into these footless socks to keep legs hot and toasty throughout the colder seasons.

The removable heating system maintains a constant temperature from approximately 20 to 35 degrees, but can be adjusted based on the temperature outside. The cordless leg warmers are heated via batteries and automatically adjusts its temperature based on the weather outside. Yamazen has a variety of styles for these items so they can be worn on your way to school or work or even at the office without worrying about tripping over cords. At 42 centimeters and weighing only 450 grams, they're easily transportable for travelling purposes.
