NJN neoprene, which stands for National Japan Neoprene, is a high-quality rubber, highly elastic, with hydrodynamic penetration improved by 10% compared to standard smooth-skin neoprene. Its distinguishing feature is its medium density, meaning excellent resistance to compression—even at increasing depths, the rubber maintains its thickness without losing heat.
We have tested this rubber under high pressure at various points, confirming its effective thickness memory, which guarantees incredible resilience. Therefore, NJN neoprene is recommended both for demanding spearfishers and for freediving and deep diving applications.

Features of NJN Neoprene
STRENGTHS
Why choose this material
CR (Cloroprene) / Neoprene
The rubber used for wetsuits is the most elastic and is made from chloroprene rubber (CR), commonly called neoprene, which offers high thermal insulation.
Currently, CR is the only rubber suitable for this application, but in the future, more eco-friendly materials will be developed.
Jersey
Il jersey applicato sulla superficie del foglio CR è realizzato in fibra sintetica come nylon o poliestere, ed è costituito principalmente da maglia elasticizzata.
Inoltre, per quanto riguarda il jersey, è stato promosso lo sviluppo di materiali ecocompatibili come materiali riciclati e non tinti.
Quality
They maintain strict quality standards in the industry. Every day, each material is carefully inspected to ensure maximum quality.
Superstretch lined
What it is
Superstretch lining can be used both externally and internally in wetsuits. It is a fabric with exceptional elasticity, durability, longevity, and comfort, and it is less delicate than smooth neoprene.
Features
The lining adds 4 key characteristics:
- Elasticity
- Durability
- Comfort
- Less fragility compared to raw rubber
Available Versions
Superstretch lined
outside
Superstretch outer lining is available in black, in thicknesses:
- 3 mm
- 4 mm
- 5 mm
- 6 mm
- 7 mm
- 8 mm
with open-cell inside
or also available double-lined (lined on both sides) in:
- 3 mm
- 5 mm
- 8 mm
Superstretch Lined Nebula Camouflage
outside
Superstretch Lined Nebula Camouflage – outside available in thicknesses:
- 3 mm
- 5 mm
- 6 mm
- 7 mm
- 8 mm
with open-cell inside
or also available double-lined (lined on both sides) in:
- 1,5 mm
Open Cell
inside
Raw rubber that ensures excellent adherence to the body and outstanding thermal insulation. It fits like a second skin but requires lubricants to wear and is more delicate and fragile.
Coating
inside
A metallic coating (gold or titanium) applied to the inner side of the neoprene. Very smooth, it allows easier wearing without lubricants and provides excellent thermal insulation. Available in 2 and 3 mm
Color: blue / titanium silver coating
Smoothskin
What it is
Smooth is an outer rubber coating similar to skin, offering excellent hydrodynamics, elasticity, and fast drying, but it is more delicate than lined neoprene.
Available Versions
Available in black, thickness:
- 3 mm
- 5 mm
- 6 mm
- 7 mm
- 8 mm
with open-cell inside
or superstretch lining inside in:
- 1,5 mm
- 2 mm
- 3 mm
- 5 mm
- 6 mm
- 7 mm
Open Cell
inside
Raw rubber that ensures excellent adherence to the body and outstanding thermal insulation. It fits like a second skin but requires lubricants to wear and is more delicate and fragile.
Superstretch lined
inside
Highly elastic fabric that does not require lubrication and is more durable than open-cell neoprene.
Mesh Skin
What it is
Mesh skin outer layer is a patterned rubber surface (squares/diamonds) that makes it slightly more resistant to cuts compared to smooth neoprene.
Features
Internally it features superstretch lining, a highly elastic fabric that does not require lubrication and is not delicate like open-cell neoprene. Available in:
- 3 mm
- 5 mm
