Layer the midweight Core Merino 220 Bottom when the fall frost arrives. Merino wool has a high warmth-to-weight ratio to keep you warm without a ton of bulk, and it regulates temperature well so you don’t overheat. Merino wool is also naturally odor-resistant to help you stay undetected, and our ArmorSpun merino wool is reinforced with nylon to make it last.
