Incredible t-shirts! Had ordered one of the bamboo and one of the hemp t-shirts. By mistake they sent two Hemp shirts. Which was ok with me. The quality of the shirts are incredible. Hemp is hard to explain. Has a vintage papyrus look to it but still strong. Feels great to wear while jogging. After contacting customer support about the mistake, they sent me the bamboo t, at no cost. ONNO has great customer support and def have quality products. They are going to by my go to for t's going forward. Thank you much ONNO! You stay classy. Oh, Im 5'8'' 150lbs, the Medium is a perfect fit for me.
