The Fourth Element PROTEUS II is a worthy successor to the original Proteus suit. Available in 3mm and 5mm thicknesses, the Proteus II is set to redefine the warmest suit in its class.
Water ingress is minimised by a number of design features. Glideskin wrist seals and the now famous hydrolock inner neck seal combine with watertight seams which are double glued, blindstitched and taped to keep the water out.
Thermoflex linings throughout the suit provide excellent comfort and thermal protection.
Additional Hexcore linings on the body core provide enhanced thermal performance where it is most needed for prolonged water exposure
Short and Tall sizes are available. However, these will be special orders and terms and conditions will apply. Please contact us for details
