Mountain Lab Bluetooth Heated Socks

Mountain Lab heated socks provide warmth on demand, right where you need it. A low-profile heating element completely encircles the toes and forefoot area. The element is powered by a lightweight battery housed at the top of the cuff, where it won't interfere with tall boot cuffs.

The socks use a 50% wool, 50% polyester blend for continuous warmth and comfort, even in damp conditions or when the socks are not powered on.

Left and right markings on the socks help with easy identification.

The Bluetooth Heated Socks use the Mountain Lab smartphone app to control the heated socks through Bluetooth connectivity. Each sock can be controlled individually for heat intensity and turned on and off. They can alternatively be controlled by a button located on the cuff of the sock, for use without the app.
