Description

Incorporating highly advanced thermal technology and one of the most insulating materials ever developed, the HALO AR's performance exceeds the expectations of any diving undersuit.

Using technology initially created for space exploration and cryogenics, the HALO A°R features the extreme insulation material ARGON™ aerogel in a compression-resistant matrix.

The HALO A°R not only provides phenomenal insulation but also offers a comfortable and practical design. Its wind and water-repellent stretch outer layer, along with thumb loops and foot stirrups, ensure a snug fit and ease of movement. This, combined with its thin and less buoyant profile, makes it a perfect choice for all-day wear.

ARGON™ aerogel, a unique form of insulation developed for space crafts and cryogenics, is the key to the HALO AR's superior performance. Unlike traditional aerogel, A°RGON™ is a foam-embedded version, making it lightweight, hollow, and flexible, perfect for diving. This innovative material was tested over a decade ago and has since been a game-changer in the diving industry.

With phenomenal insulation properties, this material enables the HALO A°R to achieve extreme thermal protection from a thinner, less buoyant diving undersuit. With a wind—and water-repellent stretch outer layer, comfortable thumb loops, and foot stirrups, this garment can be worn in total comfort all day.
