Boiled Half Zip Men

Centuries-Old Technique, Modern Mountain Performance

Amundsen Sports took an Austrian wool-boiling tradition that's been perfecting warmth since before Gore-Tex existed and built a sweater that belongs in your year-round rotation. The Boiled Half Zip starts oversized, gets boiled back to fit, and emerges with a dense, windproof structure that laughs at crisp fall mornings and doubles down under a shell when winter gets serious.

This isn't your grandfather's wool sweater—it's better. The boiled front and back panels deliver weather resistance where you need it most, while stretch-knit side panels keep you mobile. Worn solo on autumn trail days or layered beneath a shell when the mountains turn moody, this piece adapts to whatever the forecast throws at you. And because it's 100% Merino wool, it insulates even when wet, breathes better than synthetics, and ages like a fine piece of gear should.
