What Our Gearhead® Experts Are Saying: "I like the Yotei Classic because it’s warm enough to wear solo on mild days but roomy enough to pull over a base layer when it’s colder. The 100% merino feels soft, breathes well, and never smells, even after a long trip." We keep the Mons Royale Yotei Classic Long-Sleeve Shirt in rotation year-round for its adaptable comfort. Made from 100% merino wool, it delivers natural warmth, breathability, and odor resistance—making it just as suited for layering on the mountain as it is for wearing on its own around town. The relaxed cut moves easily over a base layer when extra warmth is needed, while the soft merino fibers sit comfortably against the skin without itching. From road trips to multi-day tours, the Yotei Classic handles changing conditions with ease. Merino’s moisture-wicking performance keeps us dry during high-output days, and its odor resistance means it stays fresh between washes, making it a true travel and adventure staple.
