Icebreaker Men's LS & SS Zip Shirts

Whether you want warmth for winter sports, breathability for summer hikes, or great-fitting comfort all year long, these Icebreaker men’s tops have a lot to offer. Made from 100% merino wool or a wool blend, they provide extra UV protection and prevent clamminess. Plus, they’re naturally antibacterial and odor-resistant, making them great for multi-day treks and any trip that calls for a light pack with fewer garments. This drop includes base and mid layers that vary by sleeve length, zipper length, and head coverage (hooded or hoodless)—pick the one that suits your needs.

In all three long-sleeve styles, flatlock seams prevent chafing, while the thumb loops and and droptail hem provide protection and coverage. The two Compass styles—one with a shaped hood and the other with a full-length zipper—have the added benefit of a zippered sleeve pocket for stashing small essentials.

Both short-sleeve styles use Icebreaker’s Cool-Lite technology with a blend of merino wool, Tencel, nylon, and Lycra to wick moisture and increase drying time. Eyelet panels improve ventilation, while the bonded seams and collar reduce unwanted bulk. Pick the crew neck or, for even more temperature regulation, the half-zip version.
