Long-sleeved wool t-shirt
Wool T-shirts are now my goto shirt. Modern 100% merino wool fabrics are better than cotton even in topical weather. They dry quick, never smell, feel nice. Since I live in perpetual autumn, and work indoors, I wear long-sleeved wool t-shirts. Logo-less brands, such as Meriwool and Merino.tech are not expensive ($49) and offer a long sleeved T in three weights from light to heavy, and many colors. — KK
