What is required for a heated undergarment to function effectively?

For a heated undergarment to function effectively, it needs a reliable power source, typically connected to a battery. This connection ensures that the heated elements of the undergarment receive power to generate warmth, which is essential for maintaining body temperature in cold water environments.

While some undergarments may require a connection through an opening in the suit (often for a power cord), this connection must facilitate the flow of electricity from the external battery to the heating elements. The functionality relies heavily on this direct connection to ensure sufficient power is delivered to keep the diver comfortable while diving in colder conditions.

In this context, having no specific connection would mean that the undergarment would be ineffective, as it would not receive the necessary power. Similarly, relying on wireless technology or external connections that do not adequately transfer power would hinder the heated undergarment's effectiveness. Thus, the proper connection is integral for the heated undergarment to operate as intended.
