Frequently Asked Questions
It depends on the listing. The Powersocks Heat Fusion Uni set includes two S-Pack 700B Bluetooth batteries. The sock-only Heat Fusion and the Ultra Warm Comfort S.E.T. need S-Pack batteries bought separately. The Ultra Heat Boost gloves come with their batteries and a USB cable, but no wall charger.
The Ultra Warm Comfort S.E.T. gives up to 9 hours with the S-Pack 1400B. Run time depends on the heat level, the battery size, the cold and the age of the battery, so start on level 1 and save level 3 for a quick blast on a cold chairlift.
Yes, once the batteries are unclipped. For the Powersocks Heat Fusion, turn the socks inside out and machine wash at 30 °C or below on a low spin, with no bleach or fabric softener. Remove the batteries after every use and before washing.
What we stock from Therm-ic
• Heated socks: the Powersocks Heat Fusion Uni warms all around the toes, with three heat levels; buy it sock-only or as a set with two S-Pack 700B Bluetooth batteries. The Ultra Warm Comfort S.E.T. is a thin, high-cut 50% merino sock that gives up to 9 hours of heat with an S-Pack 1400B, in sizes 35-36 to 45-47.
• Heated gloves: the Ultra Heat Boost Gloves Men have three heat levels, up to 10 hours from the included batteries, PrimaLoft insulation, a leather palm and a 10K/10K membrane.
• Batteries and spares: S-Pack batteries, the Powergloves replacement battery and a USB charging cable.
Choosing an S-Pack battery
The S-Pack 700 is slim, with 1400 mAh per battery and button control; the 700B adds Bluetooth. The S-Pack 1200 has 2400 mAh per battery and is Therm-ic's most popular. The 1400B is the most powerful, at 2800 mAh with Bluetooth, and the one Therm-ic recommends for the Ultra Warm S.E.T. Bluetooth packs pair with Therm-ic's Heat Control app.
Cold toes in Japan and the Aussie Alps
A bluebird morning in Niseko at minus double figures, or first chair at Perisher in July: switch the socks on at the bottom of the lift and start on level 1. Cold air and a low charge both shorten run time, so keep level 3 for when you need it. For other heated gear, see heated socks and heated gloves.
