The Arctic Expedition brings fourth element's knowledge of performance fabrics and body-mapped design together to create a new undersuit in its high performance Expedition Series. Enhanced insulation is provided in key exposure areas by extra layers of high-density fleece and water-resistant, windproof panels. The outer fabric is protected with a ceramic print to minimise any effect of abrasion from the inside of the drysuits, and water-resistant fabric provides further protection to the knees and seat: invaluable when getting ready on a wet dive deck. Unique thumb loops prevent the sleeves riding up when donning the drysuit, but retract to prevent them being caught in the wrist seals. A zipped hip pocket is positioned for ease of access whilst wearing a cross zip drysuit, without needing to remove the suit and is ideal for carrying a key. Handwarmer pockets provide additional comfort. Pre-drilled for p-valves.
