Outdoor Research Revel Convertible Cap On multiday trips, you’ll likely want more versatility than a typical sun hat offers. Now, you don’t have to carry two lids, or sacrifice comfort with a hat that works in one environment but not another. The Revel has two domes—a thin, stretchy nylon inner cap for breathability and sun protection, and a seam-taped, waterproof/breathable Pertex Shield DS stretch rain cover that unfurls from a pocket in the brim.
The Pertex beaded melting snow on trail runs and let tons of sweat escape on power hikes. Nice feature: The easy-adjust Velcro strap locked the hat to our tester’s melon in high winds. $36; 2 oz.; outdoorresearch.com
