Pre-owned in good condition, the foam has been replaced with a removable piece (to keep the form of the hat) I suppose the original foam disintegrated. The previous owner must have tried to remedy the issue by sewing something inside judging from stitch marks (see last three photos for details. The foam placed inside now works well to keep the hats shaped and could be washed and or  replaced easily if you wanted to. The band is discolored a little bit from age and being worn. Please see photos for more details on condition and thank you for your interest.
