What Our Gearhead® Experts Are Saying: “I like this for high-output winter days when temperature swings are constant. The half zip makes it easy to dump heat, and the zoned panels actually make a difference when you’re working hard.”The Merino 200 ZoneKnit Long Sleeve Half Zip Thermal Top focuses on movement-driven comfort , combining natural merino performance with targeted ventilation. The midweight 100% merino fabric is mapped with ZoneKnit technology to place breathable eyelet mesh in high-heat areas. A half-zip design allows quick temperature regulation, while raglan sleeves and a gusseted construction support unrestricted movement. Flatlock seams reduce friction, thumb loops keep sleeves in place, and a dipped hem adds coverage, making this a reliable next-to-skin layer for demanding cold-weather days.
