The POLAR SEAL heated garments can be washed by hand with warm water (30ºC / 86ºF) and an ordinary mild detergent. They should, however, not be wrung or 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.
We provide more detailed washing guidance in the Instruction Books.
