The Fourth Element J2 base layer is designed for extended use under a drysuit and features excellent anti-microbial performance thanks to the use of silver ion technology and outstanding wicking from a unique fabric. A simple, close fitting design with flat seams for next-to-skin comfort offers the perfect solution under any drysuit underwear. This top is not only easy to don, it has great aesthetics and is extremely comfortable thanks to excellent all-way stretch fabric. Keeping the skin dry can be critical to success, whether it is staying warm, or preventing infections. The J2 base layer 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 base layer ensures better thermal protection. The J2 base layer system takes this performance further with tried and tested anti-microbial silver ions embedded within the fibers 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 fibers of the under-suit. Even in the event of a suit flood, the J2 will retain some of its performance. Silver ions are incorporated into the fibers 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 fibers of the garment. However, this will not adversely affect the naturally occurring bacteria on the skin itself.
