The Lundhags Prime Merino Half Zip Womens is an exceptional base layer designed for winter adventures. This sweater combines single jersey merino wool with a grid-constructed merino fleece to provide optimal warmth and insulation. The grid fleece captures more air, adding insulation to critical areas like the chest, while the back panel and undersleeve allow for enhanced ventilation. A tall collar offers protection against wind and rain, and the front zipper allows for easy adjustment to regulate ventilation. Constructed to avoid chafing from seams when carrying a backpack, this garment ensures comfort during multi-day hikes. Made from merino wool, it features temperature regulation and odour resistance, keeping you warm, dry, and fresh.
