Commercial Delta Flex Semi-dry Wetsuit

Ordering Code: DELTA-FLEX

Comprising of a 5.5mm semi-dry steamer, 6.5mm shortie and a 5mm Supervent neoprene hood, the three-piece Delta Flex Semi-Tech offers year-round wetsuit diving and gives excellent thermal protection in single-figure water temperatures.

The anatomically designed Delta-Flex system can be worn with the steamer and shortie together for cold conditions, or if preferred these two garments can be worn separately for warmer dives.

Both the steamer and shortie include Northern Diver’s Ti-Ax® Thermacote® heat reflecting lining and an anti-bacterial coating. To further boost its thermal qualities, the steamer features our unique Thermal Shield vest.

The suit is constructed from soft black superstretch neoprene, a wonderfully strong and supple neoprene with flexible qualities that assist with dressing and undressing.

The suit’s comfort factor is enhanced with the use of our acclaimed smooth skin neoprene for the wrist and ankle seals, complemented with zipped protective warmers. Seals are worn inverted to ensure suit “flushing” is kept to a minimum.
