Our female testers loved the year-round performance of this midweight, which comfortably took testers from winter sweatfests in the single digits to early spring hikes in Colorado’s Front Range (the men’s NTS Mid 250 Crew, $95, has a similar design, minus the hood). It worked just as well as an insulating summer midlayer as it did next to skin. And its casual, not-too-techy style made it a favorite for après ski and around-town wear. “Warm enough to protect me in a whiteout on Colorado’s St. Mary’s Glacier, yet it wicks well enough for cross-country skiing and winter runs into the 20s,” reports one tester.
“Plus, I could wear it over a thinner baselayer for more moderate activities in cold weather without it feeling too snug.” Testers also raved over fit: “The hem is low enough to prevent stomach-exposing ride-ups.” Extra credit: thumbholes that don’t pinch and a snug hood for extra insulation. Like most 100 percent merino shirts, the hoody resists odors for days, zips moisture away evenly (testers noticed no pooling in high-sweat areas), and felt dry after 10 to 15 minutes. $125; 8.5 oz.; w’s XS-XL; smartwool.com
