This is a semi-dry suit from O'Neill. I accidentally bought two and tried to return one, but was told I couldn't, so I'm listing it here. I do windsurfing and wing foiling, and I always use O'Neill wetsuits. They are soft, and the inner material has excellent heat retention, making them warm wetsuits. It's a short chest zip type. - Brand: O'Neill - Model: Semi-dry suit - Color: Black - Size: L - 5mm/3mm Retail Price: ¥77,000 Never worn. It's brand new. I'm open to price negotiations. Thank you very much.
