Thank you very much for viewing. I am selling this item to declutter. This is a Water Land jacket. I do not know the detailed product information. I purchased it over 20 years ago and I remember wearing it about 5 times at the time. After that, it was stored in a storage room at home for about 20 years. The fabric has not deteriorated much, and I think the condition is good. Please understand that this is based on my personal assessment. I don't really want to part with it because it's part of my collection, but I hope you will consider it as a used item. The size is M, but it's a large fit. Thank you.
