Midweight Stretch Long-Sleeve 1/2-Zip - Men's

What Our Gearhead® Experts Are Saying:

"This is one of those base layers you end up reaching for year-round. It’s breathable, stretchy, and great at managing moisture, so it works for everything from winter layering to cool-weather runs. The half-zip adds easy venting, and the thumbholes keep sleeves in place when you're stacking layers. A super dependable piece for high-output days."

The Columbia Midweight Stretch Long-Sleeve 1/2-Zip is the layer we count on when temperatures drop but our plans stay ambitious. Its Omni-Wick fabric keeps sweat moving and evaporating quickly, helping us stay warm during early starts and cool during steep climbs. Four-way stretch ensures unrestricted motion whether we’re skinning up a ridge, hauling a pack through switchbacks, or reaching for holds on a cool-weather climb.

Flatlocked seams and an ergonomic design reduce friction for long-wear comfort, while the half-zip neckline offers instant climate control when our pace picks up. Thumbholes keep sleeves anchored beneath midlayers, sealing out drafts and simplifying transitions. From winter skiing to shoulder-season hiking, it’s a versatile piece that adapts seamlessly to the rhythm of the day.
