everal years ago most wetsuit manufacturers began using neoprene blends. They are adequate for watersports such as windsurfing and water skiing where the wearer stays at surface level (or just above the surface if they’re good). However, for diving, where the suit is subjected to compression, these blends just don’t perform as well as Wetwear NCN. This is why at Wetwear we won’t use anything else.

Periodically, different neoprene makers contact us touting their neoprenes for diving, Some even claim their best grade is as good as Wetwear NCN. Naturally, we are interested and curious to see if it might be true. We have them send us samples of their best. Once we get them, we put them in our compression chamber where the truth comes out.
Their very best, brand new, flattens under pressure, far more than the Wetwear NCN samples in our chamber, which have usually already been subjected to numerous compression cycles (which would tend to lower their recovery from being compressed).

We wish that it were otherwise. We would very much like to see one of the other neoprene manufacturers turn out a product that was truly as good as Wetwear NCN. Wetwear NCN  truly is the very best neoprene for sport diving available anywhere in the world and we are committed to making the very best wet suits available anywhere. For us, there is no other choice in neoprene.
It’s as simple as that. That has been true for the 25 years we’ve been making wet suits. It’s why we won’t use imported neoprene and neoprene blends.

Many of the blended suits have a one way stretch, their greatest amount of stretch is limited to one direction. Depending on which way the material is used when constructing the suit, it could mean that it stretches laterally when you put it on, and has little flexibility should you raise your arms, have a wide kicking stance, or put on a few pounds.

Wetwear NCN does not compress as much as the neoprene blends, which means it offers more insulation from the cold water around you and keeps you warmer as you dive deeper. In fact, it barely compresses during the first atmosphere, stabilizes and compresses little after that. It also holds up better under repeated use. The neoprene blends lose their elasticity after repeated dives and tend to get crinkled and wrinkled. Wetwear NCN neoprene keeps its good looks and elasticity much longer and will outlast three or four of the neoprene blend suits making it more cost-effective.

An added benefit is the reduction of buoyancy changes due to wet suit compression.

  • Wetwear NCN neoprene is 100% neoprene
  • No natural rubber
  • No SBR (plastic polymer)
  • No blends
  • That’s why it is so warm and durable

You might think that such superior quality and durability commands a much higher price. Think again! Our suits are competitive against many of those neoprene blend suits, especially when you factor in durability and value. Why would anyone buy less than the best under these conditions (once they know the difference)? Even if you don’t buy from Wetwear, do yourself a favor, make sure your next wetsuit is made of nitrogen composed neoprene.
