The Fourth Element Xerotherm Wrist Warmer is designed to be under drygloves, they bridge the gap between the undersuit and dry glove liner.

The wrist warmer sits below the drysuit seal, it allows air to equalise with the dryglove, avoiding squeeze. In the case of a glove failure, the fabric is not too bulky, therefore water will not flush through the seal.

The double layer of Xerotherm fabric on the inside of the wrist provides increased protection for an area where blood flows close to the skin surface, which makes the hands stay warmer for longer.
