The Therm-ic Ultra Warm Comfort S.E.T. heated socks set with S-Pack 3000B batteries is a complete kit for skiers who want warm feet even in severe frost. The heating runs along one thin elastic seam above and below the toes, so thanks to Smart Elastic Technology (S.E.T.) the sock fits the foot well, including inside a ski boot. Two powerful Bluetooth batteries are already in the box, so you get everything you need at once.
Ultra Warm Comfort S.E.T. heated socks – merino wool, a thermoregulating knit and an ergonomic fit around the foot, ankle and calf.
Two S-Pack 3000B batteries – 3 heat levels via the button on the battery, or more precise control in the Heat Control App on your smartphone.
USB-C charging cable – with two connectors, so you can charge both batteries at once.
Level 1: up to 14 hours
Level 2: up to 6 hours
Level 3: up to 4 hours
Real-world run time depends on the selected heat level and the outside temperature. You can also find the batteries on their own as S-Pack 3000B batteries.
S.E.T. technology – the whole heating system runs in one discreet elastic seam that warms under and above the toes without spoiling comfort.
Merino wool and a thermoregulating knit – optimal insulation and breathability.
Moisture-Vent technology – micro-channels move moisture away from the foot to keep it dry.
Ergonomic fit – the socks hug the foot, ankle and calf precisely.
These unisex socks suit alpine skiing and snowboarding, but also cross-country skiing, snowshoeing, hiking and hunting. They come in five sizes from 35 to 47. If you are between sizes, choose the smaller one. If you would rather buy the socks without batteries, see the separate Ultra Warm Comfort S.E.T heated socks, or the SET with S-Pack 1400B batteries.

Remove the batteries before washing.
Turn the socks inside out and machine wash at a maximum of 30 °C with a low spin speed (max. 400 rpm).
Do not use bleach or fabric softener, do not tumble dry, and dry flat.
Recharge the batteries at least once every 6 months.
