What Our Gearhead(R) Experts Are Saying: "I've used this as an active midlayer on cold hikes, and the Omni-Heat(TM) Arctic tech adds noticeable warmth without bulk. The stretch side panels make a big difference on steep climbs, and the thumbholes help keep sleeves in place when layering under a shell. It's lightweight but surprisingly efficient." When frosty air greets us at the trailhead, we zip into the Arctic Crest Hybrid Full-Zip Jacket from Columbia and keep moving. Part of the Columbia Titanium line, it's built for high-performance days in cold conditions where lightweight efficiency matters most. Omni-Heat(TM) Arctic solar-capture insulation, inspired by arctic wildlife, boosts warmth by harnessing the sun's energy while maintaining breathable comfort. A 40g Microtemp XF II layer adds lightweight insulation, and stretch side and underarm panels allow full mobility on climbs and scrambles. Zippered chest and hand pockets secure essentials, while thumbholes and stretch binding at the cuffs and hem help seal out chill. Designed for active hiking, this hybrid fleece keeps us warm without slowing us down.
