Super light. Super breathable. Super quick-drying. Super sun protection.The only things missing from this technical hoodie is an S on the chest and your favorite super hero inside. To just say that Patagonia's Sunshade Hooded Sun Shirt is lightweight doesn't convey how ultralight it truly is. Weighing in at a you'll-hardly-notice-you-even-have-it-on weight of 6.1 ounces (less than four of those toaster pastries you shouldn't but do eat), this sun shirt supplies all the breathable, 50+ UPF sun protection your upper body needs to not only survive, but thrive in those sweltering days out fishing the flats on your skiff. Damaging UV rays don't stand a chance with a hood that shields your head and neck and fits over your favorite fishing cap, a wrap-over design neck that offers super airflow in addition to shade for your sensitive throat area and thumb holes on the cuffs that make sure the sleeves cover the backs of your hands. All this plus it's made with fabric that's certified as bluesign approved (more on that below) so you know you're minimizing your impact on Mother Earth. 3.5oz., 100% polyester double knit.
