Bundle - S-Pack 700B Batteries + Ultra Warm Performance S.E.T® Heated Ski Socks

Get the most out of your time on snow with this high-performance heated sock bundle, pairing the precision-fit Ultra Warm Performance S.E.T® socks with S-Pack 700B Bluetooth batteries. Designed for expert skiers who need maximum responsiveness and targeted warmth in extreme conditions, this bundle keeps your feet warm, dry, and supported from first lift to last run.

About the Socks – Ultra Warm Performance S.E.T®

The Ultra Warm Performance S.E.T® socks are thin, technical, and built for advanced skiers who require a low-bulk fit inside close-fitting ski boots. Smart.Elastic.Technology® conforms to the foot and lower leg for a locked-in feel, while the discreet 2 mm S.E.T® heating line delivers subtle, even warmth around the toes without altering boot fit or limiting movement.

The thermo-regulating knit combines naturally insulating merino wool with high-performance polyamide fibers for stretch, durability, and muscle support. Strategic mesh and insulation zones regulate the foot’s microclimate, while Moisture-Vent Technology under the arch channels sweat outward through micro-channels to keep feet dry, even during intense runs.

About the Batteries – S-Pack 700B

The S-Pack 700B is a lightweight, Bluetooth-enabled battery that provides up to 7 hours of heat on a full charge. It offers 3 manual heat settings and smartphone control via the Therm-ic Heat Control App. App levels 3, 6, and 10 correspond exactly to the manual settings, offering convenient control rather than additional heat levels. Ideal for shorter ski sessions, cold mornings, or warm-weather skiing with targeted toe heating.

The batteries attach securely to the top of the socks and charge via the included USB cable. A 5V/2A wall charging cube is required (not included) to fully recharge each battery safely. Compact, efficient, and Bluetooth-ready, the 700B is a smart choice for performance-focused skiers.
