  • Description

    The Fourth Element Arctic Expedition Unisex One Piece offers possibly the best drysuit diving insulation currently available on the market. We've seen these garments in our store and we must admit - they look toasty!

    Key exposure ares of the body are provided with enhanced insulation by extra layers of high-density fleece and waterproof, windproof panels.

    The outer fabric is coated with ceramic print to minimise any effects of abrasion from the drysuit and diver who regularly have to dress up on a wet dive deck will definitely see the benefit of having further waterproof protection on the knees and seat.

    Unique thumbloops 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 on the leggings provide added comfort. The suit is pre-drilled for p-valves

    Cocoon your body with warmth in this breathable, fleece-lined, windproof, water resistant undersuit. They won't come in higher quality or more feature-rich than this!
