Fourth Element Xerotherm Size Small Unisex Baselayer top. Scuba diving, Hiking

Fourth Element Xerotherm Unisex Top. Top has been used on numerous dives but is in fantastic condition. Wording on back is slightly imperfect but has no affect on top whatsoever. I would say top is a 8/10 in ladies size and maybe 32 chest (please check Fourth Element size guide).

No longer diving so needs to go to a new home. With flat seams and a long body to ensure that no separation between top and leggings develops, the top is the ideal next-to-skin layer under a drysuit. Thumb loops keep the sleeves in place whilst donning the drysuit and should be removed from the thumb and pushed back through the wrist seals prior to diving. The ultimate baselayer for use under a drysuit. Made using Polartec Powerstretch originally developed for NASA, the Xerotherm traps a layer of air a much better insulator than water next to the skin, keeping the wearer drier and more comfortable.

The range is designed to be worn under another undersuit or on its own under a neoprene drysuit. The knit of the Xerotherm fabric produces the fastest wicking effect of any of the products in the fourth element product range. Moisture is drawn out through the fabric along fine fibres and then spreads out over the outer surface. This maintains a thin layer of air next to the skin. This is so effective in the Xerotherm that some wearers report experiencing minor suit leaks during the dive without even noticing until after the dive.

Lightweight low bulk and buoyancy.
