Therm-Ic Heat Fusion One + Spack 2400

This product is not sold in United States.
Heated socks with 2400 mAh batteries. Technical socks, free of wool.
Therm-Ic has been a reliable name in heated socks, insoles and gloves for years. This pack includes ski socks and high-capacity batteries.
Heat Fusion One socks are made for skiing, snowboarding, ice fishing, snowmobiling and any other situation where even proper winter boots or ski boots won’t keep your feet warm enough.
These socks are made entirely of technical fibers, meaning they’re comfy even for people who get itchy from wool.
- Sock materials: 52% polyamide, 36% polyamide microfiber, 7% polyester, 5% elastane
- A Fusion heat element at the front of the foot
- Pack contains two socks and two S-Pack 2400 batteries
- Three heat settings:
- Setting 1: battery life approx. 14 hours
- Setting 2: battery life approx. 6 hours
- Setting 3: battery life approx. 4 hours
Therm-Ic products work with your body rather than against it: they give cold extremities repeated pulses of warmth, encouraging your body to keep the blood circulating. The lowest setting in particular might feel suspiciously weak, but it’s worth giving it a try, too, thanks to the super long battery life.
