FNDN Heated 3.7V Base Layer Socks

FNDN Heated 3.7V Base Layer Socks.

FNDN rechargeable heated base layer socks, with long working hours and cozy temperature, will keep your feet warm and comfortable all day long. The base layer socks are designed thin enough to be worn under other socks or in tight form fitting situations. Forget about frozen toes or discomforting pain in the winter mornings or evenings. We've found the solution for you by designing the thinnest form-fitting rechargeable heated sock for women and men.

These socks are powered by our proprietary Radiant Core Heat technology and USB rechargeable BEGO battery system. This battery is the smallest & lightest in class, designed to provide the most power with the smallest footprint possible.

The base layer socks can also be connected to our FNDN heated base layer pants (sold separately) and controlled from a single waist control module. The heated socks offer enough warmth to provide great relief from poor circulation, arthritis, Raynaud's Syndrome and any kind of winter cold issues.
