This is a portable golf blouson from Ko Olina, Hawaii. Size S Chest width: 61 cm Length: 63 cm Sleeve length: 57 cm Material: 100% Polyester When I purchased it, I was told it was waterproof... However, I haven't worn it since buying it, so I don't know how waterproof it is. (It might be a good idea to apply a waterproofing spray.) Because it folds down to pocket size, the wrinkles are noticeable in the photos. It's small enough to fit in a golf carry bag. It measures 17x20 cm. It comes with a keychain, so you can hang it on your bag. It can also be used for warmth. This is a personal item, so please refrain from purchasing if you are sensitive about such things.
