Suggestion: Don’t even try to get a snug fit. Unlike Winter base layers, sun shirts are intended to be loose fit. The Echo’s sleeves are loose and long (on purpose) so that you can use them as gloves over the backs of your hands. I pull them up to my elbows like any other shirt when I don’t want them, or roll the cuffs when I just want regular length.
I get that. I’m not totally new to sun shirts, just the button-downs. I’m not looking for a tight fit, but if there is too much excess material it just gets in the way.
It’s a bit ironic, but a couple of years ago I was very much into cotton/natural fiber flannels, for everyday use and more laid back outdoor stuff. At the time it was really hard to find 100% natural fiber button down shirts (cotton, hemp, wool etc.), while polyester, nylon etc. was abundant. I don’t remember to what degree they were UV rated, but yesterdays experience was the polar opposite. Everything I could find was at least 40% cotton, with most being 100% natural fiber of some kind. I often go against the stream when it comes to outdoor trends, so I’m not surprised, just realizing this is again the case :D
