Spearfishing and freediving wetsuits (jacket, long john ), with open-cell interior.
Made of two different qualities of neoprene.
The ultra strech neoprene ensures extensive freedom of movement and makes ventilation easier.
Another type of neoprene, also very soft but less subject to compression, is used to create thicker sections on the body parts that are most sensitive to the cold (nape of the neck, back, etc.) during a dive.
Highly tear and rupture resistant.
