Enjoy maximum comfort and long-lasting warmth with this premium heated sock bundle, combining the plush Ultra Warm Comfort S.E.T® socks with the high-capacity S-Pack 1400B Bluetooth batteries.

About the Socks – Ultra Warm Comfort S.E.T®
The Ultra Warm Comfort S.E.T® socks use Smart.Elastic.Technology® to provide a flexible, adaptive fit that hugs the foot and calf without creating tightness or pressure points. Their thin, low-bulk construction ensures a seamless fit with ski boots, while the discreet 2 mm S.E.T® heating line wraps gentle warmth around the toes without affecting boot feel or movement.
Crafted for warmth and softness, these socks feature a thermo-regulating knit with naturally insulating merino wool for temperature control and moisture management. Durable polyamide fibers add stretch and hold, while strategically placed insulation panels and breathable mesh zones optimize airflow and heat retention. Moisture-Vent Technology beneath the arch channels sweat outward through micro-channels, helping keep feet dry during active skiing.
About the Batteries – S-Pack 1400B
The S-Pack 1400B is Therm-ic’s highest-capacity heated sock battery, delivering up to 14 hours of heat on a single charge. Integrated Bluetooth connectivity allows you to control temperature directly from your smartphone via the Therm-ic Heat Control app. The app’s 10-step scale corresponds to the 3 manual settings (level 3 = manual 1, level 6 = manual 2, level 10 = manual 3), offering more precise adjustments for comfort without changing the maximum power output.
Lightweight and compact, the batteries clip securely to the top of the socks and recharge via the included USB cable. For optimal charging speed and battery care, use a 5V/2A wall charger (not included). Designed for long ski days in cold conditions, the S-Pack 1400B keeps you warm whether you’re carving fresh tracks or pausing between runs.
