I have been using the Pelagic and Marlinstar going on my second season. The Marlinstar is a tighter cut but repells water and stains better. Both spf's work great just watch your neck . I would recommend either one but my go to is the Marlinstar, even can get Tuna blood to wash out. Also either one is not to bad in mid summer except for the real hot days with no breeze. Pelagic seems to be better in hotter weather.
I own Flat Line Fishing, a screenprinting and embroidering company. We print a lot on a material called Xdri. It has a moisture wicking, quick dry and is SPF 30+. I am printing on a few for a trade show coming up. Let me know if you want one to try out.
