How to measure

Chest: measure under your arms around the fullest part of your chest, tape level across your back and comfortably loose.

Sleeve: with your arm fully extended, measure from the center back of your neck at the spine to the wrist bone.

Inseam: without shoes, measure the inside of your leg from groin to floor.

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®.

Features

  • Materials: Alpine Merino - 250 GSM 20 micron wool, blended with 40% Bamboo Viscose, and 10% nylon for structure and durability
  • Warmth: LVL [2]
