Delivery information

As a customer, you should receive your package quickly and with the most secure form of delivery. That is why Nordic Heat has chosen to use PostNord as its delivery partner.

If you place your order before 3 p.m. Monday through Friday, we will ship the order the same day.

However, timely delivery  is dependant on PostNord and their National delivery partners. If PostNord experiences delays, this will delay delivery to you accordingly.

Product maintenance

The clothing is sewn to a very high standard, but must of course be used with care, as it contains built-in wires and cables/electronics. Therefore, avoid pulling, stretching, and tearing the products when taking them on and off. Take an extra 10-15 seconds when dressing and undressing, and your product will last for many years.

We also recommend washing the clothing in a washing bag.

Information

The Liner vest from Nordic Heat is completely thin and fits discreetly under your indoor clothes. The heating vest sits invisibly under your blouse or blazer at the garden party or under a jacket when you’re outdoors in the changeable Danish climate.

The Liner vest has a battery and efficiently transmits heat into your body through three heating zones distributed on the chest and back. Elastic material ensures fit and freedom of movement. The vest’s insulation is made from sustainable natural fibers – Fellex ECO Green.

With the super thin women’s liner vest, you can wear battery heated clothing under your indoor clothes. The women’s model has no collar but a deep neckline, so it fits under most indoor clothes.

Whether it’s a garden party or an outdoor concert, you want to look elegant and not freeze at the same time. In Denmark, the temperature can change in minutes. The Liner vest is perfect for this purpose, as it fits underneath where there is otherwise no room for battery heated clothing.

Good freedom of movement

This liner vest has a great fit due to elastic material at the sides, which provides great freedom of movement and comfort. Xtreme Comfort Technology in the production makes it breathable and flexible due to the thin microfibers.

If a cold breeze suddenly comes, just press the button and turn on the built-in heating. The heating vest is therefore also perfect for being active outdoors in changeable weather without the need for thick jackets.

Perfect for outdoors

Danish weather can turn from hot to cold in no time. The Liner vest is specially designed for our climate and can be used both indoors and outdoors. The outer fabric is durable and smooth made of rip-stop nylon. A quality product that characterizes all Nordic Heat products.

Heating zones are located in three places on the chest and back, where they send the heat into the bloodstream so it can circulate to the rest of the body.

The thin heating vest is also suitable for outdoor activities. It keeps you warm on the golf course, in the woods, in the garden or when birdwatching where you don’t move much.

The Liner vest is easy to operate. There are three heat levels that you control with a single button.

Eco-friendly insulation

The heating vest’s insulation is produced by fellex. This type is called Eco Green, which uses natural cellulose fibers from fast-growing trees that use far less water than other trees. The fibers are environmentally friendly and biodegradable. The antimicrobial properties mean no use of pesticides because the plants defend themselves against pests.

The fibers have a uniform hollow structure that ensures air flow and makes them perfect for thermal insulation.

Small powerful battery

The vest is heated by a lithium-ion battery that can heat for over five hours on a single charge.

The battery is as small as a box of matches, weighs only 116 grams and can be charged more than 500 times. You can buy extra batteries for longer trips, for example.

Layering is not necessary

The heating vest is part of a series of outdoor clothing from Nordic Heat. All products in the range are made with our latitudes in mind.

The design is well thought out, with heating zones of woven carbon fiber threads on both sides of the chest and back. Here they send infrared heat (FIR) into the deeper muscle layers. This means you can stop using the layer upon layer method for outdoor activities. The heat zones are positioned to send heat into the body where it is most effective.

Input from garment users

Nordic Heat is constantly developing and improving battery heated clothing. Lots of hunters, cyclists, anglers, divers, riders, gardeners, craftsmen and more use heated clothing as a regular part of their wardrobe. The feedback from recreationalists and craftsmen is worth its weight in gold when adjusting details and developing new features.

Wash at 30 degrees

The heating vest can be washed at 30 degrees C. So can the heating gloves and underwear from Nordic Heat. The battery should of course be removed before washing. But should you and your clothes get soaked, the battery will withstand it without a problem.

Safety is a high priority

Ensuring that the clothes are safe to wear is a top priority. We continuously test the products to ensure they comply with legislation and applicable requirements.

All products are CE and RoHS approved and are produced in a factory with high quality control, ISO9001 certification and proper working conditions.

FAQ // Frequently asked questions

Here you will find answers to general questions about Nordic Heat products.

How does Nordic Heat clothing work?

The products are heated using power from the rechargeable lithium-ion battery. The heat is generated by the sewn-in carbon fiber threads located in the heating zones and can be easily adjusted using the button to three different levels: high, medium, and low.

Do the new XL batteries fit all Nordic Heat clothing?

Yes, the XL batteries included with Base Layer V8 and V7 are compatible with all our clothing when used with a dongle/conversion cable.

A dongle can be purchased separately or together with the XL battery.

Clothing batteries - 2600 and/or 5000 mAh?

The new XL battery with a capacity of 5,000 mAh is charged via USB-C.

Although the battery is 7.4V, it can be charged with a 5V power bank, as there is a built-in step-up converter in the battery that converts 5V to 8.4V (which is required to charge a 7.4V battery).

The 2600 mAh clothing battery is charged with a 220V charger and also has a 5V output (for charging mobile phones, etc.).

Does my purchase include a charger and battery?

The new Base Layer V8 (like the previous V7) comes with an XL battery of 5,000 mAh. It is charged via a USB-C charger, which is not included. The battery can also be charged with a 5V power bank, as there is a built-in ‘step-up’ in the battery that converts 5V to 8.4V. Older Base Layer versions (before V7) come with a 2,600 mAh battery and charger, unless you have opted out of this during the purchase process. Here, you can choose to add the new XL battery with dongle (conversion cable) instead. For the soles, you can choose to use regular 5V power banks or our combined hand warmer/ power bank with 5,000 mAh or 10,000 mAh, respectively, which also has an (important) on/off function so you don't have to plug it in/out every time you want to turn the heat in the soles on/off. 5000mAh provides approx. 5 hours of constant heat on a single charge – 10000mAh = 10 hours.

How long do the batteries last?

Depending on the heat level selected (to make it easy to remember), the following approximate times apply for clothing: 2600 mAh: Red = 2 hours - Yellow = 4 hours - Green = 6 hours. 5000 mAh (new XL battery): Red = 4 hours - Yellow = 8 hours - Green = 11 hours Heavy-duty gloves, mittens, jackets, vests, etc. last a little longer than the recommended times, so add about +10%. It is also important to note that the battery's full capacity is only achieved after 8-10 full charges and discharges. If you start using your clothing and find that the battery does not quite live up to the recommended heating times, this may be due to a battery that is still ‘young’. The accompanying battery instructions should always be followed.

How can I get the most out of my Nordic Heat products?

'Warm hand in a warm glove'.
In general, make sure to turn on the heat before you get cold. This is important, as the technology is designed to keep you warm, not necessarily to heat you up. Therefore, you may find that you don't get very warm, but on the other hand, you won't freeze either – only when the heat is turned off.

Please note that the underwear, which is close to the body, becomes very warm at the highest heat setting (Red). This setting is only intended to provide a “burst” of heat here and now (we recommend a maximum of 10 minutes at a time on RED), after which you should turn it down to medium (Yellow) or low (Green). This will also make the battery last longer on a single charge.

Can you burn yourself on your clothes?

Yes, in principle it is possible (but only if used incorrectly).

The underwear fits snugly and can become very hot (54°C*) at the highest temperature setting (Red). If the body cannot absorb any more heat in the blood and nerve pathways, the heat is “rejected” by the body and the skin remains at 54C - this can cause red marks.

If you experience discomfort in the form of “tingling or prickling” or similar, it is of course important to turn down the heat immediately.

We recommend a maximum of 10 minutes at the highest setting, RED, at a time!

We do not recommend that the underwear be used by children, disabled persons, or persons with reduced sensitivity without supervision.

Can the temperature inside the clothing become too high?

No, it cannot.

The garment has a built-in overheating protection (mechanical TPC) that automatically turns off the heat if the temperature exceeds 55°C.

In addition, there is a safety circuit in the battery that also shuts off if there is a voltage surge in the garment.

When the skin has warmed up and can no longer absorb any more heat, it is important to turn down the highest temperature setting (red), as otherwise you risk getting red marks. Keeping 55°C directly on the skin for a long time can have consequences, and we therefore do not recommend that the clothing be used by children, disabled persons, or persons with reduced sensitivity without supervision.

Care of thermal clothing

When washing thermal clothing, you should refrain from using fabric softener, as it reduces the lifespan of the seams.

We recommend using a laundry bag for underwear and vests.

  • Icon illustrating the use of washing machine The thermal clothing can be machine washed at 40°C on a gentle cycle.
  • Icon illustrating the use of softener Avoid using fabric softener, as it reduces the lifespan of seams.
  • T-shirt and folded towels illustrated, symbolizing cleanliness and functionality. NordicHeat focuses on warm clothing designed for active lifestyles for optimal comfort and performance. The clothes must not be dry cleaned.
