Cloth Nursing Pads make sense, both for comfort and for your wallet. 

Thin yet absorbent, these nursing pads have a thirsty layer of microfleece and a layer of Coolmax next to your skin. Coolmax is a great fabric as it is used in athletic wear to pull moisture away from the body. The pads are a generous 5" diameter, allowing maximum coverage while still being small enough to fit under most bras. 

One pair is print shown and second pair is reversable black and white.
