When the fall chill starts to settle in, it's time to reach for the Core Merino 220 Bottoms.  Featuring a midweight, double-layer merino wool blend, it regulates temperature to keep you comfortable from mild early-fall afternoons through late-season cold snaps.  Merino wool is also naturally odor-resistant to help maintain stealth, and Sitka's ArmorSpun merino wool is reinforced with nylon to make sure it stands the test of time.  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.  Available in Lead.
