ONNO’s organic cotton t-shirt is soft, thin and highly breathable. If you’re going somewhere warm, wear this shirt! Which t-shirt should I buy? We recommend trying all our fabrics. Seriously, it's the only way to know which one you'll like best : ) DETAILS Organic Cotton is one of ONNO's lightweight t-shirts along with bamboo and lyocell bamboo. If you want a midweight fabric, try hemp or pima cotton. Fit: tailored, flattering but not too tight. Based on reviews, these shirts run a dash small. If you’re between sizes, or like a looser fit, we recommend sizing up. 100% organic cotton GOTS certified. To prevent shrinkage, wash cold and tumble dry low. Washing hot and drying hot can cause your shirt to shrink up to half a size. See our factory Questions about fit, or anything else?
