100% cotton. Machine washable, but we highly recommend using an environmentally-friendly dry cleaner to prevent any shrinkage or fabric warping, just in case.
*A note from the manufacturer:
A Wear More, Wash Less... Although it’s made from the same Pima cotton as your favorite everyday tee, we highly recommend taking your knits to an environmentally friendly dry cleaner once a season (unless you love shrunken sweaters). Opt for an eco-friendly fabric spray to freshen your knit between wear
