The new HALO AR for Men is a worthy replacement for the successful HALO 3D Undersuit. It has been updated with a new design, extra features and material almost out of this planet. The new Halo AR, just like its predecessor, is the warmest undergarment in the Fourth Element range of undersuits. The new wetsuit is lower in bulk and buoyancy but provides as much or more thermal protection. This exceptional undersuit will appeal to beginners, advanced and technical divers who enjoy diving in cold and temperate waters all year round. It will also work well together with Fourth Element J2 Base Layer.

The Fourth Element Men's Halo AR has a waterproof and windproof outer layer. On the inside, it is bonded to the lovely warm stretch fleece known from the Halo 3D and the Arctic undergarments. The most crucial insulating fabric, called A°RGON™, is sandwiched between these two layers. The A°RGON™ fabric was initially developed for space exploration to insulate space crafts. It has recently been used as an insulator in cryogenic chambers to make them more temperature efficient. Now it has been adopted by the Fourth Element creating this amazing undersuit for divers. We are incredibly impressed with the new fabric and sense that the Fourth Element set another benchmark for the new temperature-ultra efficient drysuit undergarments.

The design of the new Men's Halo AR concludes a few years of research and development, thermal mapping and consumers feedback from the previous models. The new Halo AR features a chest zip on the side rather than horizontally across the front to assist temperature retention in horizontal trim. The thicker layer of A°RGON™works well across the chest and tights, while thinner layers are positioned around the back of your arms, legs and torso. Routing a P-valve is as simple as adjusting the two-way zipper in the fly, and a zippered pocket provides a secure place to store keys, credit cards and cash. Finally, thumb and hill loops ensure the undersuit stays correctly on the most demanding dives. One fantastic piece of equipment for your underwater adventure!
