I purchased this at an auction. I don't have any knowledge about this item, so please examine the images carefully and make your own judgment. I believe it's unused, but it has been stored, so please be aware that there may be some minor stains or slight soiling. The size is 42-82, which I believe is roughly L-LL. Due to shipping costs, I will remove the plastic collar supports and fold the item for shipping. Thank you for your understanding.
