Therm-IC Ultra Warm Performance Set Heizsocke S-Pack 4000B

With the thin, heated Ultra Warm Performance S.E.T® functional socks – specially developed for experienced skiers in extreme conditions – you can enjoy your skiing experience even more. Thanks to their slim design and our innovative Smart Elastic® heating technology, these socks offer an optimal fit in your boots, as well as maximum comfort and a pleasant feel. The thin heating strip ensures pleasant, consistent warmth around the toes without compromising the sock’s fit.

These socks combine thermoregulatory knitting technology with merino wool – for perfect thermal insulation and breathability. Polyamide fibres provide good support and stabilise the foot during exercise. Thermal insulation structures and breathable systems have been strategically positioned to efficiently support Smart Elastic® technology. Moisture-Vent Technology absorbs moisture from the skin and promotes breathability in the foot – keeping your feet dry at all times.

In short: the Ultra Warm Performance S.E.T® heated socks offer experienced skiers an optimal fit and unique comfort. Thanks to their thin heating wire and thermoregulatory knitting technology, your feet stay warm and dry even in extreme conditions. With their slim fit and optimal foot support, these socks contribute to a carefree time on the slopes.

The socks come with a pair of S-PACK 4000B rechargeable batteries, which provide up to 20 hours of warmth during your winter outings. These batteries are equipped with Bluetooth technology, allowing you to control the warmth of your socks from your smartphone.
