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.

Xerotherm

The Ultimate Thermal Baselayer

Made using Polartec® Powerstretch® originally developed for NASA, the Xerotherm traps a layer of air to the skin, keeping the wearer drier and comfortable, making it the ultimate base layer. 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 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 maximising its thermal properties.

The Xerotherm is unrivalled by anything else on the market, it has travelled to the top of Everest and down to the Titanic.
