A novel absorbent tampon suitable for insertion into a body cavity has a substantially elongate, compressed primary absorbent structure having a first end, a second end disposed opposite thereof, and a density of at least about 0.3 g/cm3. The tampon also includes a secondary absorbent structure secured to and extending from the first end of the primary absorbent structure and extending toward the second end of the primary absorbent structure. Preferably, the secondary absorbent structure is disposed about the primary absorbent structure and forms the outer circumferential surface of the tampon. The secondary absorbent structure is capable of extending outwardly from the primary absorbent structure upon the absorption of fluid into the tampon to increase the cross-sectional area of the tampon in the body cavity. In a preferred embodiment, the tampon has sufficient column strength for digital insertion (insertion without an applicator) into a vaginal canal.
