A breathable adhesive bandage, comprising:
- a fabric layer formed entirely of wool, the fabric layer comprising wool fibers that have a fiber thickness in a range of 13 to 25 microns;
- wherein the fabric layer has a weight in a range of 5 to 15 ounces per square yard and includes oppositely disposed first and second surfaces, wherein the first surface is a brushed outer surface that is formed by brushing or distressing the first surface after formation of the fabric layer to provide extra thickness and padding or cushioning to the fabric layer;
- an adhesive layer applied to the second surface of the fabric layer in a discontinuous pattern such that the adhesive layer is configured to cover 40% to 70% of the second surface of the fabric layer;
- a pad attached to the second surface of the fabric layer or to the adhesive layer;
- and
- a removable backing, wherein the removable backing is configured to cover the pad and removably attach to the adhesive layer.
