This item was purchased by my husband around 2021 or 2022! It has been worn 2 or 3 times. ^ ^ I'm not sure of the size, so please check the measurements in the images, which were taken with the item laid flat. ^ ^ It's made of a nylon-like material and is lightweight. It may not be waterproof, but it feels like it would be okay if it got wet! Please understand that this item has been stored at home and will be shipped in a simple package. Thank you. #Camping #Camping Accessories #Outdoor Hat
