What Our Gearhead(R) Experts Are Saying:"I've worn this on cold, bright days when I'm moving fast, and the warmth-to-weight ratio is impressive. It stays breathable thanks to the wicking panels, and the thumbholes are great for keeping sleeves in place under a shell. It's a solid midlayer for variable winter conditions."We step into crisp morning air, knowing the Arctic Peak Full-Zip Jacket from Columbia will help us stay warm as the day unfolds. Its plush feel makes cold starts more comfortable, and the solar-boosted insulation captures light to build warmth without adding bulk. As the trail climbs, the fleece moves easily with us, offering the steady comfort we rely on for long hours outside. As we pick up the pace, Omni-Wick pulls moisture away, keeping the interior dry even when our effort spikes. Omni-Heat Arctic technology works in the background, capturing solar energy and retaining heat so we stay comfortable through shifting temperatures. Zippered hand pockets secure essentials, while thumbholes add protection and help the sleeves stay put beneath layers. Whether used on its own or as part of a colder-weather kit, this fleece keeps us ready for the next stretch of trail.
