Fourth Element’s J2 Baselayer range is a popular choice for protecting your skin as well as providing an extra layer of thermal protection under your drysuit. 

The J2 Longsleeve Top is designed for comfort with its soft material and flat seams. The stretch fabric and close fit ensure it is comfortable to wear for long periods of time, as well as being easy to get on and off. 

The use of silver ion technology has anti microbial properties meaning the J2 range is perfect for long wear, this, combined with anti wicking properties of the material to keep the skin dry helps to prevent infections in addition to keeping you warm. The silver ions are incorporated into the fabric meaning the anti-bacterial and anti-fungal properties last and are not washed away. 

The wicking properties draw perspiration and moisture away from the body, so, with the right combination of undergarments they even be pulled further from the skin into the fibres of the undersuit. The J2 retains some of its thermal properties even in the even of a flooded drysuit.
