£239.95

Internally sealed, versatile and virtually Semi Dry…

Diving: For most people this 3mm wetsuit is the perfect choice for the Red Sea in the spring, summer, early autumn and when the summer sun reaches the Mediterranean. Use the DeepSkin short john as an additional thermal neoprene layer under this 3mm wetsuit and you will be astounded at the increase in warmth and protection.
When wearing these two suits together you will have increased your torso thickness to 5mm, whilst keeping your arms and legs flexible and manoeuvrable. With the 2mm cell neoprene of the DeepSkin short john against your body, this combination will amaze.

Shallow summer diving in waters around 18°c is possible for certain people and the Red Sea in the cooler months would be perfect.

Don’t forget, the DeepSkin Tech Vest could be added to enhance this combination even further.
