Heavyweight socks for the heaviest winters
When the temperature drops and the trail gets gnarly, you need a sock that won’t flinch. The Mountaineering Micro Crew brings heavyweight warmth and serious cushioning — the kind of comfort you’ll be thankful for halfway up a snowbound ridge or during those icy camp mornings. The merino blend delivers natural insulation without overheating, and the fit stays locked in no matter what boots you’re wearing. If your adventures regularly take you into the cold, this is a must-pack piece of kit.
