Edun was a brand by one of Bono's daughters - it was supposedly all eco-conscious. There are no tags on this other than the brand label, but I think it was organic cotton and or hemp. It's very soft and has some stretch like a knit. Beautiful blue fabric, almost like a space dyed pattern. Two straps are included, but I'm not sure why. One could go around the neck and loop back to the front. There are only loops to connect the strap at the inside front, on either side of the V at the chest center. The loop to the right is frayed. The front is lined; the bust area is double lined. About 12 inches flat at narrowest point of waist. From a pet and smoke free home.
