The Merino 260 Tech 1/2-Zip Top is a heavyweight merino base layer designed for skiing, hiking, and cold weather. Made from 100% merino wool, it offers natural warmth, breathability, and odor resistance. Features include a half-zip for ventilation, gusseted underarms for increased mobility, offset shoulder seams to reduce pack friction, flatlock seams to prevent chafing, and side seams placed towards the back to minimize abrasion. Its slim fit allows for easy layering under midlayers and shells.
