The non-absorbent material includes a plurality of apertures through which fluid can flow to reach the absorbent material, and an overwrap material overlies the non-absorbent material to transport fluid over the surface of the non-absorbent material. Preferably the absorbent article is a tampon and the loop is ring shaped.
