Because I was expecting the Barely There microfiber bras, I found this cotton somewhat unrefined/rough on the skin. That said, this model gives much more support than the microfiber and makes an excellent sports bra, at least for smaller and mid sized breasts. Like a sports bra, it becomes somewhat constricting after a few hours wear. For me, this is not an all day bra, while the microfiber, pretty much same design except for racing back, is super comfortable, for smaller and medium sized breasts, and is my all day bra.
