Brand new for 2018 is the updated Thermocline range! It is a significant technical improvement over the original model and is also made from 33% recycled Nylon - most of which came from ghost nets pulled out of the sea! So not only will you be warm and the sharpest dressed diver on the boat you'll also be helping our oceans; what is there not to feel good about!
The original neutrally buoyant wetsuit system, Thermocline is lightweight, machine washable and equivalent to a 2mm neoprene wetsuit, without the wetsuit, making it perfect for those allergic to neoprene. Now, made using recycled Ghost fishing nets, Thermocline is part of our OceanPositive collection.
The long-sleeved top and leggings together weigh less than 1kg (2.2lbs) making them ideal for travelling and because they are not made from neoprene they can be packed without fear of them creasing or being damaged.
Made from 33% Econyl Recycled Nylon / 57% Polyester / 10% Elastane
Machine Wash at 30C
