Please note that the underwear/Base Layer, which is tight, becomes very hot at the high heat setting (RED). This setting is only intended to give a “shot” of heat now and then. Hereafter you should switch down to medium (yellow) or low (green), thus keeping the battery longer on a single charge.

Green = +5 hours. Yellow = 3 ┬Ż hours. Red = 2 hours.

It is also important to keep in mind that the full capacity of the battery is not achieved before 8-10 full recharges and discharges.

If you find that the battery does not live up to the recommended heating times, it might be due to a still ‘young’ battery.

The battery guide should always be followed carefully.

No, because the battery for the clothes is at 7.4V and the USB charger is only at 5V, this is not possible.

Not with the insoles, though – and please remember that you need two batteries here. ­čśë

You can either use any regular type of power bank or the Nordic Heat combined power bank/Hand warmer (5V), which also gives you the possibility to switch the heating ON and OFF.

Connected with our ‘Bridge Connection’/Split cable you can even use and charge two batteries at the same time.

Please remember that Lithium-ion batteries must always be stored in the cabin on board the airplane!

The clothes, with wires and electronics, on the other hand can be worn or stored as you prefer.

This will also occur if only one battery is set for charging.

Hang to dry.

The clothing has an incorporated overheat protection (mechanical TPC) which automatically switches off the heat if the temperature exceeds 55┬░ C.

Furthermore, a safety print in the battery switches off if a voltage change occurs in the clothes.

We recommend a maximum of 10 min. on the highest temperature (red)!

If the skin is heated up and therefore unable to receive more heat, it is important to turn down from the highest temperature setting (red) – otherwise you can get a burn mark! Holdning 55┬░ C directly on to the skin for an extended period of time can have consequences, and therefore we do not recommend our clothing to be worn by children, people with disabilities and people with reduced skin sensitivity.

We ship to all countries within the EU.

We also ship to the UK. ­čśë

Always remember to charge the battery completely┬ábefore storage over a long period of time (eg summer). There’s a safety print inside the battery that uses a little power all the time, and if this power runs out, the safety print shuts down the battery for good.

However, ladies must choose a size smaller in the┬áunderwear┬áthan they normally use (as sizes are men’s sizes). Ex. lady size 38 / M = choose size 36 / S.

If you are between two sizes in the underwear, always choose the larger.

Should you have any questions about the sizes, please feel free to call or write us – +45 2717 0000
