Prepare yourself for long, frozen sits with the Core Merino 330 Bottom. Heavyweight merino wool brings itch-free warmth for the coldest hunts, while a recycled synthetic lining moves any moisture away from your skin to keep you dry and warm. Merino wool also brings more warmth with less bulk and is naturally odor-resistant to help you avoid being detected. Our ArmorSpun merino is also stronger than traditional merino wool to ensure it’s durable enough season after season.
