Durably waterproof and windproof, the top of the range Illumina Neptunian Full Wetsuit Steamer 4/3MM features an exceptionally stretchable yet durable premium stretch Neoprene construction with Nitrocell Technology, hugging the body like a glove and keeping the body well insulated and warm in cool waters.

The Neptunian is designed for the avid diver, swimmer, surfer, kayaker and windsurfer. Where you require high flexibility in body and arm movement, the Neptunian provides you with it. Where you require warmth in the cold waters, the Neptunian provides you with it.

Nitrocell Technology: Engineered Nitrocell Technology provides top notch insulation, through the capturing of natural body heat radiation inside countless nitrogen bubble microcells. Nitrocell Technology facilitates the efficient use of body heat to warm up the body, preventing dissipative and evaporative body heat loss.

CR Grade Neoprene For Soft, Cushiony Feel & Incredible Stretchability: Constructed from high end, premium CR Grade Neoprene material which has superior water resistance characteristics and a pleasant, cushiony feel to the skin, as it is very soft and has incredible stretchability. Specially designed for immersing in water sports in cold climates.

Glue & Blind Single Sided Stitched Seams: The Neptunian is triple glued, double stitched at the seams, and stitched on the single side of the Neoprene, thus repelling cold water from the body, resulting in superb flexibility, superb strength at the seams, and ultimately, a Neptunian wetsuit that is as warm as a granny’s chuckle.

Fits Like A Glove: Its excellent body hugging shape means less cold water rushes in between the Neptunian and your skin, to keep you warm and snuggly.

Full Range Movement Flexibility: The Neoprene material is 4mm thick all around the Neptunian wetsuit, with 3mm thickness at the arms for superb flexibility for arm movement. Thick Neoprene provides comfortable warmth in cold waters. Great for the aqua sports person who keeps on going in the winter or spring. 

Design Features: Front entry wetsuit with a slightly higher neckline to provide more body warmth. Stash pocket located on left knee pad for those small but important things you might want to carry along in the sea.
