I used these hats for a work uniform and pressed them with htv. The vinyl took to them great, however it does have a middle seam so just be aware of that for your design. But overall very happy with them. It was flattering on both men and women.
I was looking for a good hat and I was having some real trouble finding one so I came to jiffy shirts and found this shirt here, came out very good and if I ever need another shirt like this for another event I may do in the future I will be sure to come on back to jiffy shirts to order another thank you!
