One piece cold water wetsuit made of 7 mm neoprene, with an outer layer in Elastic-Span and inner lining in Elastic-Plush. These materials make the suit warm and extremely elastic, making it very easy to put on. A YKK zipper (ensuring optimal quality) runs vertically on the back. The knees are reinforced with special protective patches. A very handy pocket on the right leg has two compartments and a useful D-ring. Double sleeves and zippers on wrists and ankles. A special sealing system on the collar minimises water infiltration.
