What's not to love? Comfort, check. Eco friendly, check. Awesome, incredible customer service, check. The bamboo tees are the best for comfort, layering in the winter, and sleeping. In other words, everything all year round. The hemp are quickly becoming my close second and will be great in the fall and even winter in Louisiana under a cardigan. I have sized up for a looser fit recently, but the cut and fabric is very forgiving depending on whether you put in a hot dryer. I have worn from small to large comfortably and I am a size medium/10 ish in tops with chunkier shoulders and arms. I currently have both medium and large depending on what I am wearing. (I gave the smalls to my daughter who also loves them now even though they are worn!)
