Incorporating highly advanced thermal technology and one of the most insulating materials ever developed, the HALO A°R's performance exceeds expectations of any diving undersuit.
 
Using technology originally created for space exploration and cryogenics, the HALO A°R features the extreme insulation material A°RGON™ aerogel in a compression resistant matrix.
 
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 is a garment which can be worn in total comfort, all day.
 
Building on fourth element's experience in thermal protection and bodymapping, the HALO A°R was assessed with thermal imaging cameras to improve and modify prototypes.
 
The offset chest zip and baffles ensure that heat lost from the torso is minimised when in horizontal trim. All the body from shoulders to knees is protected by a layer of A°RGON™, while other critical areas also benefit from this enhanced insulation without compromising mobility or creating bulk.
 
The left and right P-valve ports allow for uninterrupted routing while two zippered pockets on the legs provide secure storage for essentials.
