Description

The Northern Diver Delta Flex 3-Piece Semi-Dry Wetsuit System is designed for divers who want exceptional warmth, comfort, and flexibility throughout the year. Combining a 5.5mm long john, 6.5mm shortie and 5mm Super vent hood, this versatile system provides outstanding thermal protection for cold water dives while allowing each piece to be worn individually in milder conditions.

Built from premium super stretch neoprene, the Delta Flex offers an ergonomic fit that moves naturally with your body, making it easier to don and doff without compromising durability. The long john and shortie both feature Ti-Ax® Thermacore® titanium-lined interiors with an anti-bacterial coating to maximise warmth and comfort, while the integrated Thermal Shield vest in the long john delivers even greater insulation when diving in single-figure water temperatures.

Triple-glued and blind-stitched seams help minimise water ingress, while smooth skin wrist, ankle and neck seals reduce flushing to keep you warmer for longer. Protective YKK® zipped cuffs, reinforced knee protection and shoulder grip printing complete a wetsuit system built to withstand regular diving.

Whether you're exploring UK waters or travelling to cooler dive destinations, the Delta Flex adapts to changing temperatures by allowing each component to be worn together or separately, giving you excellent versatility from one suit system.

Six of the best cold water wetsuits

By Scuba Magazine on Jan 30, 2017

I’ve been diving on and off with an older Delta-Flex now for around five years and it has been one of my favourite to take to the Red Sea in winter. The new version looks and feels pretty similar. The one-piece suit has an average thickness of 5.5mm and the shortie has an average of 6mm. The secret of the Delta-Flex is its integrated upper vest. Made of thin neoprene with a single lined seal, you pull it over your head when donning the suit. When the suit is zipped up this upper vest makes it nearly watertight around the neck. To be honest I didn’t think it would last more than a few dives, but the previous model is still going strong. There are inverted seals around the ankles and wrists along with my pet hate – zips. Granted, zips do make putting a suit on easier but I find when removing the suit they just dig into your ankles and wrists. All seams are triple-glued and blind-stitched, making them pretty much watertight – the super-soft neoprene is incredibly flexible. At only five and a half millimetres thick, the Delta-Flex struggled to keep me as warm as the others but wait, for the price Northern Diver throw in a thicker over-shortie and hood – how good is that? This makes the combination good for most people in water temperatures in the lower teens. The outer material of my older suit was a little prone to abrasion but the new suit has a generous coating of rubber stripes and discs on the shoulders and knees respectively. Being the least expensive and including shortie and hood, the Delta-Flex is the bargain of the bunch here on test.

Great quality

By Steve on Sep 26, 2016

Bought for "varied" diving and took the whole kit to Malta recently, never used the shorty oversuit and was never cold. Must admit water temp was never below 16c but others with standard 5mm did complain of the cold on a couple of occasions. In fact the water in the legs after the dive was actually pretty warm and we never experienced any flush through. Great place to buy, from people who actually dive and who can also get alterations carried out for the non-standard people like me!

Really Good Quality Semi-Dry

By Mark Clayton on Jun 15, 2016

Used it 4 dives so far, 2 inland and 2 Sea. Only used the base suit and hood, hardly felt the water and was warm as toast. Very impressed with the quality, great fit too. On the web page it is not obvious that this package includes a matching shorty and hood. The picture of the older model shows that better. I was lucky that I could call in to Northern Diver (Wigan) to see it in the flesh/neoprene..
