Our Crewneck Guide Sweater is a thick and heavy staple that provides decades of lasting service. It's made with 100% merino wool that's tightly spun into firm yarns for a firm surface that minimizes pilling and snags. The wool is sourced from sheep prized for their long, fine fleece. Our merino wool excels at wicking moisture to its tips for evaporation and can absorb up to 30% of its weight in water without feeling damp or clammy. This natural capillary action enables wool to insulate when wet and is why it has been the fabric of choice in the outdoors for centuries. Rib-knit collar, cuffs, and hem.
