Mullion flotation suits are designed to provide both warmth and protection from the elements while working, and crucial floatation and thermal protection in the event of accidental immersion. Classified as 50 Newton Personal Flotation Devices (PFDs), these suits are waterproof, complying with EN 343, and offer comfort during use. In water, they help reduce the risks of cold shock and hypothermia, allow for easy manoeuvrability, and enhance the wearer's visibility, helping in quick location and recovery.
