Kor Alloy Crew Sweatshirt - Men's

What Our Gearhead® Experts Are Saying:

"I wear this on cool-weather hikes when I need warmth that won’t overheat me on climbs. The Primaloft Gold Active insulation takes the edge off cold starts, and the Pertex Quantum Air fabric breathes surprisingly well. The stretch panels really help when scrambling or reaching overhead, and it layers smoothly under a shell."

When crisp air settles over the trail and the miles stack up, we count on the Kor Alloy Crew Sweatshirt from Mountain Hardwear to strike the perfect balance between warmth and breathability. Designed for high-output hikes and long days outside, it keeps us comfortable from chilly trailheads to windswept summits.

Pertex Quantum Air fabric promotes airflow while resisting light weather, and strategically mapped 40g Primaloft Gold Active insulation delivers featherlight warmth across the arms and torso. Stretch panels through the sides and back enhance mobility, letting us move freely over boulders and steep terrain. The AirMesh lining boosts next-to-skin comfort and ventilation, while a zippered chest pocket and kangaroo pocket keep small essentials close. Stretch woven cuffs secure the fit, making this insulated crew a versatile layer for cool-weather adventures.
