Purchase these for bachelorette parties and they're always a big hit! Heat transfer works fine on them. Bill is not very bendable (obviously because its primarily foam); definitely meant as more of a flat bill.
Loved the feel, look and fit of the hat however, when trying to apply HTV to the hat, I was not successful. This was a personal purchase so I only made one attempt - would buy again to try another round. Overall the hat is great as a blank - not sure about printing on.
I wear the hat for personal usage and I must say that I was surprised on how good the quality is. I love how soft the brim of the hat is and how perfectly it fits. A must buy and I will be purchasing more.
