"What Our Gearhead® Experts Are Saying: ""I like this as a midlayer for cold hikes where I’m moving fast. The Omni-Heat™ Arctic tech adds noticeable warmth when the sun’s out, but it still breathes well on climbs. The bonded fleece feels lightweight and flexible, and the thumbholes plus stretch binding help seal in heat without restricting movement."" When cold air settles over the trail, we zip into the Arctic Crest Bonded Full-Zip Jacket from Columbia and keep moving. Part of the Titanium collection, this lightweight performance fleece is engineered for high-output days in low temperatures. Omni-Heat™ Arctic solar-capture technology uses dark yarns to harness the sun’s energy, amplifying warmth without adding bulk. The bonded fleece construction wicks sweat to keep us dry as effort increases, while stretch binding at the cuffs and hood brim helps seal out chill. Zippered chest and hand pockets secure small essentials, and thumbholes provide extra coverage and layering ease. Built for hiking in cold conditions, this jacket delivers efficient warmth with technical precision."
