Fourth Element Halo 3D Undersuit - Mens


Halo3D - Biomapped Thermal Protection
Maximising thermal protection whilst minimising buoyancy, the HALO 3D has body mapped insulation, strategically placed to enhance protection when in horizontal trim. Designed for use underneath membrane and trilaminate suits, the HALO 3D is the perfect complement to our current range of drysuit thermal protection. In a layering combination with Xerotherm, HALO 3D is suitable for the harshest diving conditions on the planet.

- SpaceTek Compression Resistant Materials: This 3D material is panelled on the chest, torso, shoulders and thighs to provide constant air layer to minimise heat loss especially when the diver is in horizontal trim. Horizontal trim occurs when the diver is in a horizontal position and the air migrates to the back of the suit which increases pressure on the chest and heat is also lost to the water. Large muscle groups receive a good supply of blood but air migrates into the back of the suit which exposes the muscles to heat loss.
- Enhanced Low Bulk Insulation: The forearm has been insulated to provide a warmer blood flow to hands. High density fleece layers have been applied to the crook of the elbow so that there is greater mobility. The kidney region has a larger flow of blood close to the skin surface and the Halo 3D features - 2 additional layers of fleece to minimise heat loss to the environment in this area.
- Pre-prepared holes for p-valve tubes
- Zipped pocket on the arm for small items such as a key
- Comfortable zip cover at neck
- Double headed full length zipper for convenience and ease of donning
- Elasticated waist portion to ensure close fit
- Thumb loops keep sleeves in position while donning the drysuit
