FUUBAMB00 Women's 18 Zones Heated Thermal Underwear Set

Stay warm during the coldest winter months with the FUUBAMB00 Women's Heated Thermal Underwear Set. This advanced set features 18 heating zones strategically placed at the knees, back, and waist to provide targeted warmth where you need it most. Designed for comfort and efficiency, the set uses intelligent temperature control to help you manage your heat levels easily. Made from a soft blend of 95% Cotton and 5% Spandex with a fleece lining, these long johns fit like a second skin to minimize heat loss. The breathable, moisture-wicking fabric ensures you stay dry by pulling sweat away from your body, preventing that clammy feeling during outdoor activities. Whether you are braving the elements or staying cozy indoors, this lightweight yet warm set provides a sense of security. Safety is a priority with a built-in thermal protection module and a 5V safety voltage design. The system includes an automatic shut-off feature that stops running if it overheats, resuming only once temperatures return to standard levels. Simply connect any 5V/2A USB power bank to enjoy customizable warmth through three LED settings: Red (45-55C), White (35-45C), and Blue (25-35C).
