The build quality of the Quantum is to the standard of our entire product line - all seams are 3D stitched and taped or critically taped for maximum safety with panels of DK limestone neoprene and our specially developed linings. The stretch zones are made from high quality S-Type neoprene lined with FLX lining. Our Apex Fit design ensures optimum comfort and extreme freedom of movement. Thermo is used in all upper body areas to reduce the cooling effect. The body is made from highly flexible NPM lining with exceptional surface durability and highly elasticated D-Foam neoprene. The Quantum is a ground-breaking approach for a wetsuit.
