This nonwoven pulp fiber web has a mean flow pore size ranging from about 18 to about 100 microns, and a Frazier porosity of at least about 100 cfm/ft.sup.2. The web may also be characterized by a specific volume ranging from about 8 to about 15 cm.sup.3 /g. The nonwoven pulp fiber web may contain a significant proportion of low-average fiber length pulp and still have a total absorptive capacity greater than about 500 percent and a wicking rate greater than about 2 centimeters per 15 seconds. The hydraulically needled nonwoven pulp fiber web may be used as a hand towel, wipe, or as a fluid distribution material in an absorbent personal care product.
