Wetsuit Dictionary

A Welcome to the Seventhwave Wetsuit dictionary.
The place to turn when we use a technical term and you have no idea what it means.

We'll Be adding to this list all the time, so if the word or term you are looking for isn't here check back later, or even better, drop us an email and make a suggestion for us to include.
 



Blind Stitch


BlindStitch Seventhwave Wetsuits 2Blind stitching is used when a seam needs to be waterproof. Perfect for our winter wetsuits.

Sometimes we refer to blind stitched seams as G&S or G+S which means glued and (blind) stitched or glued and sealed.

All our winter models include Glued and Sealed seams. This means that all seams are double glued and butted together to create a seal. They are then given time to completely dry and then comes the actual blind stitching. 

The actual blind stitch is created by sewing machine, it uses a curved needle and does not penetrate all the way through the piece of neoprene. This technique creates a strong seam without compromising warmth.
 



Limestone


Limestone Dictionary Seventhwave WetsuitsLimestone is probably the coolest thing we offer. In a nutshell, all our neoprene is made from limestone. Yeah it's made from rocks.
Other neoprene is made using dirty old oil, but in Japan, Yamamoto corporation cleverly devised a way to make neoprene from Limestone chips.
Why should you choose Limestone neoprene over Oil based neoprene?
Limestone neoprene has a high micro-cell structure. These are independent closed cells (bubbles basically) within the neoprene that are packed together at an extremely high density. Oil-based neoprene has a cell penetration of 60-70%, whereas limestone neoprene has a 94% cell penetration. What this means in simple terms is that limestone neoprene has a lot more air bubbles inside the rubber than other brands (over 30% to be exact), and is way less dense than oil-based neoprene.

Because of this micro-cell structure, limestone neoprene provides several serious distinct advantages to the functionality of wetsuits compared to the traditional oil-based neoprene:
 
  • It is impermeable
  • It is lighter in weight
  • It is warmer
  • It is more durable
  • It is stretchy
Our neoprene ROCKS
 

Steamer


TestSizeA full length wetsuit, arm length finishes at the wrist, leg length finishes at the ankle.
Why is it called a steamer? During our research, we found 2 reasons why a full length wetsuit could be called a steamer. 1) a term coined from Steamer Lane, a famous surfing location in Santa Cruz, California which was the birthplace of the surfing wetsuit. 2) Steamer was the name given to full length wetsuits because, when the wetsuit was removed (after being in the water) steam was pouring off the wetsuit. 

Here at Seventhwave, we don't really mind why it was called steamer, but this has become the industry standard. But, what really matters is that Steamers give you full body cover and are the warmest option. especially when combined with sealed seams (more on that in another post).
 

Titanium 2.0


Titanium Seventhwave Wetsuit DictionaryWe throw the term Titanium around a lot here at Seventhwave, "Titanium lined this", "Titanium Hot Top that". So here's some nerdy information about our secret weapon....

Titanium Neoprene was pioneered by the Japanese Yamamoto Corporation in the 1980’s (also the innovators of limestone neoprene), ‘Titanium’ is the process of applying a thin Titanium Alpha metallic alloy coating to the neoprene surface prior to the bonding of the outer jersey fabric, and is designed to reflect heat. Once it has been applied to neoprene it looks like a coating of silvery-grey paint.

How does it help me though?: As soon as you enter the water, the heat from inside your wetsuit wants to escape and dissipate. This is called thermal diffusion. As it tries to escape, the thermal heat hits the Titanium-lining that then reflects the heat back towards you, continually. In fact, every time you move, paddle, or expel energy, more heat is created inside your wetsuit and reflected back to you—increasing heat retention by an amazing 40%.

The great advantage is that you can wear a much thinner, lighter wetsuit than ever before without compromising warmth, meaning you can beat those cold water blues and leave those old-style, traditional, thicker wetsuits in the dusty closet where they belong! The thinner the suit, the more flexible you are.

And now, all titanium lined products we make, feature Yamamoto's new Titanium 2.0 (ti-2.0) which is even warmer. It basically has twice the amount of titanium lining (this increases the reflectability, keeping you much warmer.
