How Waterproof Is My Vest?

Heated vests and jackets are water-resistant, making them suitable for light exposure to moisture, such as staying warm after a swim.

However, if the product — especially the battery — is exposed to excessive water, it may stop functioning.

We strongly advise avoiding salt water, as it can cause corrosion in the heating system.
