The D1X is part of the new generation of amazing and unique Insulated Constant Volume Drysuits, developed and patented a couple of years ago. There is, so far, no followers from competitors to match these unique features. At Waterproof we have always been keen on keeping up with the latest materials and developments and the D1X is the result of this.
The outer fabric of D1X is made of soft, flexible and strong Polytech 500 Tri-Lam fabric. The patented system of D1X includes a detachable, integrated 3D Mesh inner lining – a soft and flexible material with outstanding insulation. The suit is equipped with a metal dryzipper with zipper cover, SI TECH Quick Neck System with Warm Neck, SI TECH QCS Oval Ring System with Warm Cuffs, Silicone seals for neck and wrists and SI TECH valves. The unique Warm Neck and Cuff system is keeping the diver warmer, due to reduced water movement, and also protects the seals.
All parts of the suit concerning mobility have been anatomically designed to enhance the freedom of movement. The suit has DuPont™ Kevlar® fiber reinforced knee pads, a seam-free crotch area reinforced with heavy-duty Cordura® and an anti-slip seat for grip and abrasion protection – all this to ensure an excellent durable and comfortable drysuit.

The mesh lining does not compress, maintaining a constant insulating distance between you and the cold water.


It is all a matter of keeping a layer of insulating air between you and the cold water. The Patented 3D Mesh inner lining works like a thermos bottle. It creates what we call a Constant Insulation Volume.


The Patented 3D Mesh inner lining provides an unrestricted airflow and prevents trapped air. It makes buoyancy control easier and controls the inner climate.


The constant distance and unrestricted airflow provided by the 3D Mesh inner lining keeps moist air away from your body. As a result, you will feel dry and warm.


The 3D Mesh has exceptional resistance to pressure. It provides real pressure distribution and keeps the distance constant to the outer shell. This virtually eliminates squeeze and cold spots.
