What Our Gearhead(R) Experts Are Saying:"This top is my go-to for the coldest ski days. The fit is sleek, the merino is super soft, and the roll neck offers the perfect coverage when winds pick up-no extra neck gaiter needed."When deep winter arrives, we reach for the 300 MerinoFine Roll Neck Thermal Top. Designed for frigid alpine missions, this heavyweight base layer wraps us in warmth thanks to its ultrafine 15. 5-micron merino wool construction-soft, breathable, and naturally insulating. The roll neck keeps cold air out without the need for a separate gaiter, and thumb loops make layering under gloves a breeze. With mobility-boosting raglan sleeves and flatlock seams that minimize friction, this top layers comfortably under shells or midlayers. From icy lift rides to snowshoe treks in single digits, the 300 MerinoFine(TM) keeps us warm, dry, and ready to push deeper into winter.
