I love these jawns; have a bunch of ‘em.
Started in on them because, much like
@Murge, I sweat up on my dome a good bit & was staining/bleaching cotton hats where & when salt would accumulate; I’d clean them up by washing them, but the bleached parts remained.
Figuring a synthetic won’t fade nearly as quickly, I gave one a try & it’s not only fairly cool, but blocks wind well on cooler days too.
When it comes to cleaning: a quick rinse in the sink or tub, followed by a brief hang-dry (they are a quick dry material, after all) & they’re demineralized/looking good again.
If you use terms like “quick dry,” “Nylon” & “surf cap” in your search you’ll find a whole world of blank samples in a variety of colors awaiting your parusal.
