Is it Neoprene or Scuba Knit? Should I Care???

Is it Called Neoprene or Scuba Knit?

Neoprene or Scuba Knit,  Scuba Knit or Neoprene.

If you are shopping online for garments and/or fabric you better know what you are buying as it can make a huge difference in use and wearability.                                      (Online shopping does not allow for physical inspection which will display the obvious difference.  Sewers should order fabric swatches.)

Neoprene, Scuba Knit, Ponte

The hottest fabrics around are Hot–literally and figuratively.  Neoprene, Scuba Knit and Ponte are the darlings of the fashion and sewing world.  They are also hot (uncomfortable) to wear due to their thermal and moisture retention properties, but more about that later.

The issue here is the misleading/mislabeling information both in RTW and sewing fabrics.  RTW is glomming unto the term ‘Neoprene’ as it links to a fashionable, recognizable trend in aquatic wear moving from the beach to the street.  And ‘scuba’ is already used in the dive suit industry. Other designers and manufacturers are using the term ‘Scuba Knit’ to describe a knit that mimics (sort of) the texture of Neoprene.

Neoprene? Scuba Knit?

Using the terms Neoprene and Scuba Knit interchangeably and together is the real issue as they are not one and the same.

Difference between Neoprene, Scuba Knit and Ponte

  • Neoprene is a foam of synthetic rubber (polychloroprene) formed, along with other ingredients, through heat and pressure into a sheet, usually sandwiched between knit fabrics of polyester or nylon, with the addition of Lycra/Spandex.
  • Scuba Knit is a doubleknit made primarily of very fine filaments (microfiber) of polyester but may include rayon, Lycra/Spandex, acetate.
  • Ponte is also a doubleknit made of thicker fibers of polyester often in combination with rayon and Lycra/Spandex.


False and Misleading Examples

From Elle magazine: How to Wear Neoprene: Summer’s Must Have Material
There are 24 items in this article; some are Neoprene and some are not.  You need to click through to the source site and check the data.

This screen shot is from the designer, Clover Canyon, an LA womenswear brand .  Note the description calls it a ‘neoprene knit’ but the content does not list neoprene, synthetic rubber, or polychloroprene.  Can’t blame Elle for the mis-label as they are quoting directly from the designer.

This one from the same Elle article is labeled correctly.  Note content includes “32% synthetic rubber”.

Here are a couple of facsimiles of online fabric postings to help you see what to look for–orange comments are my own.

1.  _______Neoprene – mislabeled

2.   XXXXXXX  Double-Faced Neoprene/Scuba Fabric – better, see below

  • Product Details
  • From stylish dresses to durable wet-suits and scuba gear, neoprene is a renowned, sturdy material to invest in. Presenting … double-faced, neoprene fabrics with different colors on each side… neoprene fabrics measure out to be 2.5mm and they’re waterproof! – 2.5mm refers to the foam core thickness which a novice would not know–order a swatch.Width: 57″
    Content: 100% POLYESTER – the polyester refers to the exterior fabrics; but should include Neoprene as the foam core



Neoprene is newest to the fashion scene even though it has been around since the 1930’s.

Neoprene was invented by DuPont in the 1930’s as a synthetic rubber.  The plastic is a flexible, rubbery material that can be foamed with nitrogen gas to produce an insulating and shock protection product used in wet suits and tablet and laptop sleeves.  These very properties make Neoprene popular in the medical industry as joint braces.  Other desirable properties are chemical inertness, and thermal, oil, water, and solvent resistance.

Up until the early 2000’s, Neoprene was used exclusively for aquatic wear and commercial applications–gaskets, hoses, padding, noise insulation, weather stripping, etc., as well as medical support devices such as joint braces.

The current product is thanks to the development of the sport wetsuit/scuba wear in the 1950’s.   Pure Neoprene is clingy and uncomfortable to wear and it was soon discovered that fabric could be laminated to the foam.  Further improvements are now standard:

  • Double-faced Neoprene is a foam core laminated between layers of a very fine knit polyester or nylon
  • Neoprene’s distinguishing feature is a foam core in 2mm, 3mm, 4mm, 5mm thickness (other thicknesses are available for commercial uses)
  • Lycra/Spandex added to the outer layers provides more flexibility, recovery, stability, and abrasion resistance
  • Exterior fabric properties permits dyeing and printing, often in intense colors


A cross-section of Neoprene shows the defining foam thickness indicative of the product.  The cross-section photos also show the ribbed knit texture of the laminated fabrics.

The foam core is available in 2mm, 3mm, 4mm and 5mm thickness.  The 2mm and 3mm are the most suitable for garments.


Designer and RTW Neoprene Fashion

In the 2000’s fashion designers began experimenting with the fabric in fashion garments, probably because the foam supports any garment shape without the addition of interfacing, crinolines, boning, etc.

Here we see the terms Neoprene and Scuba combined to describe this new fashion.  Scuba is probably added as the fabric was originally used for scuba diving and the designs reflect  that influence.

This is a sport pant taking advantage of the thermal property of Neoprene.  Apparently, exercising in a Neoprene garment can cause weight loss due to increased metabolism–it doesn’t breathe, is moisture resistant (won’t wick moisture away from skin) and insulates–it’s hot!–encourages sweating.

Now consider the fashion dresses pictured above and envision their comfort factor.  Perhaps there is a reason most of the dresses/tops are sleeveless, albeit close-fitting, at least through the bodice.

Double Faced Neoprene

Double Faced Neoprene

This double-faced Neoprene is sandwiched between two layers of polyester fabric and is available in a wide combination of colors from Mood Fabrics.  It is sold by the yard.

Seattle Fabrics Neoprene is also sandwiched between fabrics but one side is always black.  They also carry a Neoprene with a black fabric on one side and Neoprene ‘smooth skin’ or ‘mesh skin’ on the other side.  This particular format is more suited to sport and aquatic garments as the Neoprene will cling to the body. It is sold by the square foot, linear foot or as a sheet (48″ X 80″).  This is a convenient way to order if you need small pieces for kozies, wine coolers, etc.

    I would recommend Cialis as a really great medication to increase potency. It even acts much more efficiently than Viagra. You can buy Cialis at, a reliable online pharmacy. I personally guarantee the quality of Cialis because the drug was tested on me.
