The Merz b. Schwanen Merino Crew Neck is the shirt you never knew you needed. It takes the simplicity of a long sleeve t-shirt and upgrades it with incredibly soft merino wool. The result is a classic long sleeve shirt that is as high-performance as it gets. Merino wool is soft, sweat-wicking, and thermo-regulating so it keeps you cool in the Summer and warm in the Winter. It's sustainably sourced and also anti-microbial so you don't need to wash it as often, both of which make it more environmentally friendly as well. And just in case this wasn't enough, the shirt is circularly knit so it the classic Merz details like triangle inserts under the arms and no side seams making it unbelievably comfortable.
