This listing is for an Arizona State University Sun Devils snapback adjustable hat, which was made by California Headwear, and is one size fits most due to its adjustable nature. The hat may have had foam insulation inside on the underside at one point, but that is not present now if it was there originally. The hat's bill feels bent a bit in the middle, but it still lays flat when worn. The hat also has a smudge at the upper right in the white ares, and the sweatband has several ripples (see pictures). The hat has definitely has wear, but it remains a wearable and usable vintage hat. Please see all the pictures of the actual hat in this listing for more details. Thanks for looking, and let me know if you have any questions.
