Mountain Khakis Peaks Flannel Shirt

“If I could get away with it socially, I’d wear this shirt every single day,” raves a female Colorado tester. “It’s the only button-down I’ve ever slept in.” The roomy-but-flattering cut layers well over tees and under puffies, but the real secret is the fabric: a cozy, poly/wool/Lycra blend. Lambs-wool (10 percent) adds the perfect amount of warmth for cool evenings and helped keep stink at bay on a weeklong fall trip in Utah’s Canyonlands; poly (88 percent) feels soft and wicks sweat; and Lycra (2 percent) increases stretch, so even when testers were climbing the shirt didn’t feel constricting. Only gripe: It’s slow to dry. $90; 5.7 oz.; mountainkhakis.com
