I purchased this hat based on the only other review that was available. Reviewer stated this was the only hat she uses to apply printing and embroidery to and rated it 5stars. My sole purpose was to apply a separately purchased patch to it. It is 100% acrylic as described. The label states:Hand wash cold water.Dry flat.NO HEAT.Made in Korea. So I am unable to use it for intended purpose. The dimensions are as described.In fact the hat looks exactly like the picture which unfortunately is not at all flattering on a female as it has the odd shaped,squared off top. So even if it could withstand any amount of heat I would not have applied the patch I paid twice as much for because of the odd shape.
