This is a semi-dry 5/3mm chest zip full suit. It comes standard with an inner neck, which prevents water from entering and improves heat retention. It also has a brushed lining for added warmth. This is a domestically produced semi-dry wetsuit, with meticulous attention to detail in the sewing, specifications, and every aspect of its construction. It has been used for two seasons, but since I rotate between two semi-dry suits, it hasn't been used that much in practice. Therefore, I think it can be considered a clean used item. Please be aware that some water entry is possible. Size: ML 1. Height: 172cm 2. Weight: 62kg 3. Neck: 36cm 4. Shoulder Width: 44cm 5. Chest: 92cm 6. Waist: 72cm 7. Hips: 88cm 8. Back Length: 67cm 9.
