FAQ - Heated Clothes

Are Polar Seal tops safe?

The POLAR SEAL electrical elements are low voltage (5V) and can be safely used in clothing. The maximum temperature reached on the surface of each heating element is 50°C / 122°F and it is limited by a controlling thermostat. Further, the zip-top, hoodie, vest and parka are CE approved. (EMC, RoSH and Safety).

What types of Power banks shall I use?

Your POLAR SEAL is powered by an external 5V compact USB power bank (not provided) with an output of 2A or more (with USB-A connector) delivering 5,000 to 20,000 mAh, which you can procure online or from most electronics stores in your country.

Why is the power bank not provided?

This open compatibility allows you to choose the power bank of your liking, in terms of brand name, size, capacity, color etc. 

  • If you have chosen the POLAR SEAL heated top, we recommend that you choose a light power bank, with a capacity of 5,000 to 10,000 mAh.
  • If you have chosen the POLAR SEAL heated full-zip hoodie, we recommend an average capacity of around 10,000 mAh.
  • If you have chosen the POLAR SEAL vest or parka, we recommend a large power bank, delivering up to 20,000 mAh.

Where do I insert the Power Bank?

You insert this power bank in the left pocket and connect it to the USB plug located inside the pocket. You can use the right pocket to carry your phone, wallet, or an extra power bank for longer heating time. The USB pocket dimensions are 21 cm of height and 11 cm of width. 

How long can I stay warm?

Using your power bank to supply two heating zones at a high level, your POLAR SEAL will heat you up for the following periods of time.

 5,000 mAh 
Around 4 hours autonomy
10,000 mAh
Around 8 hours autonomy
20,000 mAh
Around 14 hours autonomy

If necessary, you can use the spare right pocket to store an extra power bank, thereby extending the heating time to a whole day.

(Data subject to variation depending on the quality & age of the power bank)

How do I wash my POLAR SEAL?

The POLAR SEAL heated garments can be washed by hand with warm water and an ordinary mild detergent. They should however not be ironed. The USB connector is protected during wash once you cover it with the built-in rubber cover. You should always make sure that you remove the power bank from the pocket before washing your POLAR SEAL.

Can I use my heated POLAR SEAL for water sports?

The Polar Seal heating elements can withstand water. However, the clothes cannot be used for water sports, because they are too heavy, and the power bank would be damaged by immersion into water.
