This Mercer+Mettle men's crew is perfect for various situations like casual outings or workdays. It's designed for men who value both style and comfort. The shirt is made of a 5 - ounce 92/8 poly/spandex jersey (6.2 - ounce 94/6 poly/spandex jersey for white color), which gives it a great stretch and moisture - wicking ability. You can wear it on its own during warm days or layer it under a jacket when it's cooler.
