Using strategically placed additional layers of high density fleece and wind and waterproof fabrics to protect critical areas of the body that experience greater exposure during the dive, the biomapping technology maximises thermal protection whilst minimising bulk, allowing greater freedom of movement and comfort throughout the dive.

With warm, water resistant chest panel and sleeve panels, the Arctic Expedition top combines biomapped enhanced insulation with practical considerations for the dive. The windproof chest panel eliminates the rush of cold air when pressing the chest inflate valve. The bungee cord thumb loops ensure that the sleeves do not ride up when donning the drysuit, but retract to prevent them becoming trapped in the wrist seals.
