What Our Gearhead(R) Experts Are Saying: "This is my go-to baselayer for big ski days. The merino is super soft, never itchy, and does a great job regulating temperature when I'm climbing or descending. The zip neck is perfect for quick venting too-it's just dialed." Whether we're skinning into the backcountry or lapping stormy tree runs, the Ortovox 185 Rock'N'Wool Zip Neck Top is the first layer we count on to keep us warm, dry, and comfortable all day long. Made from 100% virgin merino wool with an ultra-fine 19-micron fiber, this baselayer feels luxuriously soft against the skin while naturally managing moisture, regulating temperature, and resisting odors-even after a full day of effort. The half-zip design lets us quickly adjust airflow on steep climbs or sunny ridgelines, while the updated colorblock style and twisted yarn bring fresh energy to our winter kit. From dawn patrol to apres, this versatile layer is a must-have for freeride-focused missions and backcountry tours alike.
