Women's Thermocline Leggings

large – Change

Thermocline

"A neoprene-free alternative to a traditional wetsuit made with recycled ghost fishing nets. Neutrally buoyant, lightweight and with a fleece lining that provides the equivalent warmth of 2mm neoprene, this is perfect for travel and tropical diving."

Informations

Neoprene free

Thermocline provides a solution for many people who suffer from neoprene allergies either by replacing the traditional wetsuit entirely or acting as a barrier, reducing contact between the skin and the wetsuit itself.

Resources

Utilising a unique fabric made using ECONYL® recycled Nylon from ghost fishing nets, laminated with a waterproof membrane and thermal fleece, Thermocline revolutionises
the notion that being environmentally responsible means sacrificing performance or aesthetics.
