The Yotei BF LS by Mons Royale is a long-sleeved shirt for many occasions made from soft, breathable merino jersey: warm in cold weather and highly breathable in warm weather. The longer cut, fitted shirt has flat seams for comfort without chafing, while long sleeves with thumbholes ensure comfort. And because merino wool is odor-resistant, you can wear it again and again and again before it needs to be washed. A sporty yet extremely relaxed shirt for all occasions.
