Maximize your skiing performance in the coldest alpine conditions with this elite heated sock bundle, pairing the Ultra Warm Performance S.E.T® socks with S-Pack 1400B Bluetooth batteries. Built for skiers who demand precision fit, foot climate control, and long-lasting warmth, this set delivers reliable comfort and technical performance on even the longest days in the mountains.

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

The Ultra Warm Performance S.E.T® socks are thin and highly technical, engineered for a low-profile fit inside performance ski boots. Smart.Elastic.Technology® wraps the foot and calf for a precise, adaptive hold without bulk or pressure points, ensuring optimal boot response. A discreet 2 mm S.E.T® heating line delivers subtle, even warmth to the toes without affecting fit or flex.

Constructed with a thermo-regulating knit, these socks incorporate naturally insulating merino wool for warmth and breathability, while polyamide support zones provide structure and muscle stability. Strategically placed insulating panels and breathable mesh zones work in synergy with Smart.Elastic.® to maintain an ideal foot climate. Underfoot, Moisture-Vent Technology channels sweat away from the arch through micro-channels, helping to keep feet dry during high-intensity skiing.

About the Batteries – S-Pack 1400B

The S-Pack 1400B is Therm-ic’s most powerful battery, delivering up to 14 hours of heat with three manual settings or app-based control via Bluetooth. The Therm-ic Heat Control app allows you to fine-tune warmth in real time, with app levels 3, 6, and 10 corresponding directly to manual settings 1, 2, and 3 — providing more adjustment flexibility, not increased maximum output.

Lightweight and compact, the batteries clip securely to the sock cuff and recharge via the included USB cable. For optimal charging performance, a 5V/2A wall charger is required (not included). Designed for extended use in harsh winter conditions, the S-Pack 1400B is ideal for all-day resort skiing, ski touring, or back-to-back runs in sub-zero temperatures.
