Glacial Trail 1/2-Zip Top - Women's

What Our Gearhead® Experts Are Saying:

"This is my new favorite layer for high-output missions. It’s breathable, stretchy, and surprisingly tough for how light it is. The mock neck and grid fleece interior make it super cozy when the wind picks up on exposed routes."

We asked the pros what they needed, and the Mountain Hardwear Glacial Trail 1/2-Zip Top is the answer. Born from the feedback of guides who live in the alpine, this layer is engineered for technical ascents, fast-moving trails, and exposed ridgelines where every ounce—and every detail—matters.

Inside, the soft brushed grid fleece offers breathable warmth that won’t overheat, while the abrasion-resistant stretch fabric outside holds up against rocks, pack straps, and surprise gusts. The half zip adds venting on the fly, and the high mock neck offers quick, reliable coverage when the wind kicks up. With three zippered pockets for essentials, it’s built to go light, layer cleanly, and handle whatever the summit throws your way.
