4th Element's warmest undergarment, equivalent to a 400g thinsulate with less bulk due to body-mapped insulation and strategically placed compression-resistant Spacetek material in key exposure areas to maximise insulation when diving in horizontal trim.
The one piece design is simple and functional; lower profile around the hips and midriff, allowing high maneuverability with panels of additional thermal protection layers located where they are needed most, enhancing the thermal protection in critical zones without excessive bulk. It can be worn as part of a layering system with Xerotherm and in extreme cases, even Arctic.
Maximizing thermal protection whilst minimizing buoyancy, the Halo 3D has body-mapped insulation, strategically placed to enhance protection when in horizontal trim. Designed for use underneath membrane and trilaminate dry suits.
Convenient zipped sleeve pocket, full length double-headed zip with internal and external zip cover, thumb loops to aid donning, secure foot stirrups to prevent legs riding up, simple one piece design, machine washable and quick drying.
