Fourth Element Undersuits

Fourth Element Undersuits are well know with divers thanks to their amazingly low bulk and ability to keep the user warm even in the event of a suit flood. Fourth Element under suits are designed to be worn in layers staring with Fourth Element Drybase, then Fourth Element Xerotherms and finally Fourth Element Arctics. The Fourth Element Halo 3D is unique in its design and is becoming increasingly popular for use in even the coldest of waters.

No matter which water temperature you intend to dive in the Fourth Element Undersuit range can provide the exact amount of insulation required.

    Worn underneath neoprene boots, Finsocks help to keep the feet a little warmer and assist with the donning of a wetsuit by providing a low friction contact between the feet and the inside of the wetsuit.

    They are also ideal for children and young adults whose feet are still growing as they can help a pair of fins which are a little too large fit better and last longer.
