One piece cold water wetsuit made of 5 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
