Fourth Element HALO A°R Men’s Drysuit Undergarment – Elite Cold-Water Thermal Performance
Dive longer and stay warmer in cold Southern California waters with the Fourth Element HALO A°R Men’s Undergarment, the most advanced drysuit undersuit available for cold-water scuba diving. Designed using breakthrough technology inspired by space exploration and cryogenics, the HALO A°R delivers exceptional warmth with reduced bulk—making it ideal for technical, recreational, and extended dives in Los Angeles and beyond.
At the heart of this premium diving undergarment is A°RGON™ aerogel insulation, one of the most effective insulating materials ever developed. Encased in a compression-resistant matrix, A°RGON™ provides extreme thermal protection while remaining thin and low-buoyancy, allowing divers to maintain proper trim and comfort throughout the dive.
Precision Design for Warmth, Comfort, and Mobility
Advanced body-mapped thermal insulation, developed using thermal imaging, strategically places insulation where heat loss is greatest. The torso—from shoulders to knees—is fully protected with A°RGON™ insulation to maximize warmth while maintaining a horizontal trim position underwater.
A wind- and water-repellent stretch outer layer, combined with an offset chest zipper and strategically placed baffles, minimizes heat loss without restricting movement. Features like thumb loops, foot stirrups, and a two-way P-valve compatible zipper ensure a secure fit and ease of use during long or technical dives.
