This is a non-zip type semi-dry suit. It's been about 5 years since I bought it, but I haven't used it very often. There's some water leakage from cracks under the arms. The holes aren't big, so I think they can be repaired. I think you can use it as is, unless it's in freezing cold water in mid-winter. How about it if you want to try a non-zip suit, or a semi-dry suit? I am: Height: 168cm Weight: about 67kg It should be the best size for me. Surfing Dry suit Full suit
