@GeneralPublic it's honestly all up to you for the closure and I can understand you want to keep with the trucker theme. But regardless of the material the hat is made from I think that snapbacks just do not look good on 5 panels. It makes them look cheesy and almost like you're trying too hard to try and get kids that are both interested in snapbacks and 5 panels to buy them. To be honest I couldn't suggest a "better" form of closure per se. I'm not trying to bash this hat, just definitely not me.
Also, I got my caps from indiegogo like you said, and I really like them. Great quality and the fit is the best I think I have out of any of my 5 panel collection, which includes Supreme, HUF, RipnDip, TQL, The Decades, so on and so forth... So bravo on those! Not the best costumer feedback but I got em, so job well done.
