I initially bought 2 ONNO Bamboo shirts. When I found them to be too shear, the company very kindly offered to refund my money or let me exchange them for something else. I choose 2 hemp/cotton shirts and loved them so much I bought 3 more. They are light, breathable, soft and very comfortable. Also, the ONNO company suggested I donate the Bamboo shirts to someone in need rather than send them back. PLUS, the company uses paper/cardboard mailers for shipping. This is why I love ONNO - they make great clothes, have a moral compass and they care about the environment.
