You do know the difference between being comfortable or miserable in the cold? A good wool base layer. If that sounds overly simplistic, you probably aren't taking advantage of the incredible insulating properties of wool when braving the winter weather. Smartwool's Merino 150 Base Layer – available for both men and women in bottoms, long-sleeve, and short-sleeve tops – is an excellent option whether you're planning a day on the slopes or just want to stay warm while shoveling the sidewalk. Made of 87 percent Merino wool and 13 percent nylon, the fabric offers a smooth next-to-skin feel while still retaining wool's insulation.
The smooth flat-lock seams also keep you from chafing, and the offset shoulder seams make carrying a pack more comfortable. The fabric is very breathable and is great at wicking away moisture, so it's a great performance fabric when you're sweating during a ski run or snowshoe hike. Yet it will still keep you warm on the chairlift ride back to the top. Merino wool even has anti-bacterial properties that prevent it from stinking after a long day of use. So quit shivering – put on a pair of bottoms and a long-sleeve top and go enjoy all that winter has to offer.
