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 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.
We 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.
