Like the DeltaFlex Omega, the hard-wearing properties of the DeltaFlex do not detract from the superb comfort offered by the super-stretch DFN-Ultragrade™ neoprene.

The internal lining offers superb warmth and insulation with its Ti-Ax® Thermacote® Titanium Terry lining, now with anti-bacterial coating.

The build quality is exactly what divers have come to expect from Northern Diver wetsuits offering tough water-tight seams, high quality materials and components and exceptional quality control.

The DeltaFlex SemiTech will fit everyone, no matter what their size. The ergonomic cut of the suit plus the preformed and shaped arms and legs offer maximum in-water comfort.

The suit’s 6.5mm Long-John undergarment doubles as a one-piece wetsuit for warm water diving and a step-through hood-attached jacket with a warmth retaining lining.

High quality superstretch 5.5mm/6.5mm neoprene with silver Titanium Terry lining with anti-bacterial coating.

Superstretch for absolute comfort - you will fit into these suits whatever your size because of the superior ergonomic cut and preformed & shaped arms and legs - which also provides maximum in-water comfort.
