Fourth Element Halo AR Undersuit

Incorporating cutting-edge thermal technology and one of the most advanced insulating materials ever developed, the HALO A°R sets a new standard for diving undersuits.

Engineered with technology originally designed for space exploration and cryogenics, the HALO A°R utilizes A°RGON™ aerogel, an extreme insulation material embedded in a compression-resistant matrix. This innovative material offers unparalleled insulation, allowing the HALO A°R to deliver superior thermal protection with a thinner and less buoyant design.

The undersuit's wind and water-repellent stretch outer layer, along with comfortable thumb loops and foot stirrups, ensures all-day comfort, even in the most demanding environments. Leveraging fourth element’s extensive expertise in thermal protection and body mapping, the HALO A°R was rigorously tested and optimized using thermal imaging cameras to fine-tune its design for maximum performance.

The offset chest zip and baffles are strategically placed to minimize heat loss from the torso when in horizontal trim, while the A°RGON™ layer provides full-body protection from shoulders to knees. Critical areas benefit from enhanced insulation without adding bulk or restricting mobility.

For added convenience, the undersuit features a two-way zipper for easy valve routing and a secure zippered pocket to safely store keys, credit cards, or cash. The HALO A°R combines advanced technology, comfort, and performance, making it the ultimate choice for serious divers.
