509 FZN Merino Pant
509 FZN Merino Pants
FZN stands for Five Zero Nine, not frozen, and that’s exactly how you’ll feel in the 509 FZN Merino Pant. This base layer pant provides versatile midweight warmth with a high-performance Alpine Merino wool blend that’s naturally breathable, fast-drying, and odor-repellent—all without the itch. It’s far superior to conventional fabrics and compared to grandpa’s wool knickers, it’s like upgrading your sled from his 1978 Panther to a PRO-RMK®.
