Fourth Element have moved to a universal system (XS, S, M, L etc) from a number system (UK12, US10 etc) to help ensure that you can find your perfect size whether you are shopping online or purchasing from our store.
During the transition period Fourth Element will sell garments labelled with either old or new sizing. This might lead to you receiving an item labelled with a different size to your order. Don’t worry! The measurements match according to the size guide, and you will receive your order with the fit that you want.

The Fourth Element Thermocline Jacket is a lightweight, breathable garment that is easy to don and quick to remove. The environmentally friendly fabric ensures that it is comfortable whilst preparing to dive and the design allows great freedom of movement along with the ability to unzip a little to keep cool before the dive.
Pair this with the leggings to give full length neutrally buoyant thermal protection that dries quickly and is machine washable; always ready for next getting in the water.
The Thermocline fabric is an extremely comfortable and lightweight alternative to neoprene which is what most wetsuits are made from. It is lightweight, doesn't crush when folded, dries really quickly and is machine washable. Simply put, it is the perfect tropical diving suit. On top of that, the suit is neutrally buoyant, allowing less lead to be worn.
It is also much more eco-friendly than neoprene. Utilising a unique fabric made using ECONYL 100% recycled nylon from ghost fishing nets and other discarded waste, laminated with a waterproof membrane and thermal fleece, Thermocline revolutionises the notion that being environmentally responsible means sacrificing performance or aesthetics.
FEATURES:
- Neoprene free
- Outer contains 78% recycled Nylon
- Lightweight
- Wind and waterproof fabric
- Breathable
- Neutrally buoyant
- Machine washable
- The equivalent of 2mm neoprene
Add Mcnett Neoslix to aid with the donning and doffing of the suit as well as to prolong the life of the seals too.
