Core - Bodywarmer

The Core bodywarmer is the perfect solution for divers looking for additional thermal protection on longer or colder dives. Designed to work with either the Arctic or Xerotherm under trilaminate or neoprene suits, the Core provides outstanding thermal protection for the body torso whilst allowing maximum freedom of movement of the arms.

Insulating critical areas of the torso with additional layers of high thermal performance fleece equips the Core bodywarmer to become an essential part of a diver’s thermal systems.

Extra insulation in the kidney region limits heat loss from this high blood flow area. The chest and upper torso (often the first areas to get cold due to the redistribution of air within a drysuit) are also protected by more layers of high density fleece.

A removable crotch strap, secured with elasticated loops hold the Core in position during the dive, if required.

The Core is also designed to work well above the surface, featuring fourth element’s XWPs SOFTSHELL water-resistant fabric and zipped handwarmer pockets and welded chest pocket with water-resistant zip.
