9 Exceptionally Warm Winter
Midlayers With Omni-Heat™ Helix

Here’s the best winter gear featuring Columbia Sportswear’s new Omni-Heat™ Helix technology
BY DAVID YOUNG
Not long after Popular Science named Omni-Heat™ Black Dot one of 2020’s “100 Greatest Innovations,” Columbia Sportswear is back with more industry-leading warming technology—and this time it's in your midlayers.

Dubbed Omni-Heat™ Helix, the new fabric technology relies on small performance heat cells that are modeled after closed-cell foam insulation.

“These little cells hold your body heat,” explains Dr. Haskell Beckham, Columbia’s senior director of innovation. “Once that heat warms up those pods, the air inside the cells can’t simply rise and escape as hot air wants to do.”

The technology—which is found in fleece, knits, and other midlayers, as well as select hats and gloves—is the latest in a string of cold-weather innovations, including Omni-Heat™ Black Dot and Omni-Heat™ Infinity, the latter of which uses NASA-inspired material to reflect body heat back to you.

In honor of this new technology, we’ve rounded up nine of our favorite Omni-Heat™ Helix midlayers to help you stay warm in cold weather.
