The Arctic Expedition brings fourth element's knowledge of performance fabrics and body-mapped design together to create versatile, high performance drysuit underwear.. 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. Handwarmer pockets on the leggings provide additional comfort. Pre-drilled for p-valves.
