Minus33 Midweight Merino Quarter-Zip Crew

Named for famous landmarks in the American Northeast, the Minus33 Isolation and Sequoia lightweight quarter-zip crews provide sun and insect protection in the spring and fall—and double as base layers for cross-country skiing and other cold-weather activities in the winter. The 230 g/m2 interlock knit is made from 18.5-micron merino wool and the flatlock seams prevent chafing when you’re on the move. The mock neck adds warmth without being too bulky and sits close to the neck to give you extra insulation between your neck and your second layer. The chest zipper on the top increases ventilation on balmy days, and you can zip it up for extra warmth when you need it.

Founded in Ashland, New Hampshire, in 1916, Minus33 makes high-quality performance apparel for outdoor enthusiasts. The staff (a bunch of outdoor enthusiasts themselves) test their products all over the state, in some of the country’s harshest weather—the CEO uses Minus33 merino wool in his hunting apparel, and the Senior Vice President in his mountain biking gear. Today, a century later, the company continues to operate on the grounds of its original mill site.
