Fourth Element HALO 3D

$679.00

ADVANCED TECHNOLOGY THERMAL UNDERSUIT

Our warmest undergarment, equivalent to a 400g thinsulate with less bulk due to body-mapped insulation and strategically placed compression-resistant Spacetek material in key exposure areas to maximise insulation when diving in horizontal trim.

Maximising thermal protection whilst minimising buoyancy, the Halo 3D has body-mapped insulation, strategically placed to enhance protection when in horizontal trim. Designed for use underneath membrane and trilaminate dry suits.

Convenient zipped sleeve pocket, full length double-headed zip with internal and external zip cover, thumb loops to aid donning, secure foot stirrups to prevent legs riding up, simple one piece design, machine washable and quick drying.

Fourth Element J2 Baselayer

$273.00

EXTENDED BASELAYER PERFORMANCE

Baselayer protection for extended range diving. Developed using antimicrobial silver ion treatments, this fabric was tested in the extreme environments of the J2 cave system, one of the deepest in the world. It is stretchy, warm, and won’t let you down.

With excellent anti-microbial performance thanks to the use of silver ion technology, and outstanding wicking from a unique fabric, the J2 baselayer is designed for extended use under a drysuit.

Keeping the skin dry can be critical to success, whether it is staying warm, or preventing infections. The J2 baselayer was designed to wick perspiration away from the skin and maintain a dry zone next to the skin. Air is a better insulator than water and consequently, the baselayer ensures better thermal protection.

The J2 baselayer system takes this performance further with tried and tested anti-microbial silver ions embedded within the fibres of the fabric. This enables long, repetitive wear without the risk of skin infections developing – something which was critical on the US Deep Caving Team’s 2013 expedition to explore the Cheve cave system in Mexico, for which the J2 was specifically developed.

The J2 wicking performance also comes into its own when the fabric gets wet. Water is wicked away from the skin, and with the right combination of drysuit underwear, further away though the fibres of the undersuit. Even in the event of a suit flood, the J2 will retain some of its performance.

Silver ions are incorporated into the fibres when they are manufactured, ensuring that the bacteriostatic and anti-fungal properties of the fabric last. This cannot be washed off. The silver ions prevent the formation of bacterial cell membranes, preventing most bacteria from growing in the fibres of the garment. However, this will not adversely affect the naturally occurring bacteria on the skin itself.
