1. A sanitary napkin for placement in a crotch portion of an undergarment of a wearer, comprising:
- a) a liquid-absorbing section for absorbing bodily exudate, said liquid-absorbing section including a longitudinal axis, a front portion and a rear portion, said liquid-absorbing section including;
(i) a fluid-permeable cover layer;
(ii) an absorbing system underneath said fluid-permeable cover layer;
(iii) a liquid-impervious barrier layer underneath said absorbing system b) a breathable extension component projecting from said liquid-absorbing section, said breathable extension component including a proximal edge and a distal edge spaced from said proximal edge by a distance of at least about 2.5 cm, said proximal edge being united to said liquid-absorbing section;
c) said breathable extension component being adjacent the rear portion of said liquid-absorbing section;
d) said breathable extension component having at least a portion of its extent that manifests a moisture vapor transmission rate of at least about 3000 g/m2/day;
e) said breathable extension component having an average absorption capacity that is substantially less than an average absorption capacity of said liquidabsorbing section.

Abstract
A sanitary napkin including a liquid-absorbing section for absorbing body exudate and a breathable extension component adjacent the rear portion of the liquid-absorbing section. The breathable extension component is preferably free of absorbent material and has a moisture vapor transmission rate of at least about 3000 g/m2/day to allow moisture trapped between the breathable extension component and the skin of the wearer to evaporate.

26. A sanitary napkin for placement in a crotch portion of an undergarment of a wearer, comprising:
-
a) a liquid-absorbing section for absorbing bodily exudate, said liquid-absorbing section including a longitudinal axis, a front portion and a rear portion, two longitudinal sides opposed to one another and extending between said front portion and said rear portion, said liquid-absorbing section including;
(i) a fluid-permeable cover layer;
(ii) an absorbing system underneath said fluid-permeable cover layer;
(iii) a liquid-impervious barrier layer underneath said absorbing system b) a breathable extension component projecting from said liquid-absorbing section, said breathable extension component including a proximal edge and a distal edge spaced from said proximal edge by a distance of at least about 2.5 cm, said proximal edge being united to said liquid absorbing section;
c) said breathable extension component including a segment projecting from a longitudinal side of said liquid-absorbing section, said segment being adjacent the rear portion of said liquid-absorbing section;
d) said segment manifesting a moisture vapor transmission rate of least about 3000 g/m2/day;
e) said breathable extension component having an average absorption capacity that is substantially less than an average absorption capacity of said liquid-absorbing section.

27. A sanitary napkin for placement in a crotch portion of an undergarment of a wearer, comprising:
-
a) a liquid-absorbing section for absorbing bodily exudate, said liquid-absorbing section including;
(i) a longitudinal axis;
(ii) a front portion and a rear portion;
(iii) two longitudinal sides opposed to one another and extending between said front portion and said rear portion;
(iv) a pair of flaps projecting from said liquid-absorbing section along generally opposite directions, each flap being adjacent to a respective longitudinal side and being capable of being folded about the crotch portion of the undergarment of the wearer when the sanitary napkin is placed in the crotch portion of the undergarment of the wearer;
(v) a fluid-permeable cover layer;
(vi) an absorbing system underneath said fluid-permeable cover layer;
(vii) a liquid-impervious barrier layer underneath said absorbing system;
b) a breathable extension component projecting from said liquid-absorbing section, said breathable extension component including a proximal edge and a distal edge spaced from said proximal edge by a distance of at least about 2.5 cm, said proximal edge being united to said liquid-absorbing section;
c) said breathable extension component including a portion that is spaced apart from one of said flaps relative the longitudinal axis of said liquid-absorbing section;
d) said portion manifesting a moisture vapor transmission rate of at least about 3000 g/m2/day;
e) said breathable extension component having an average absorption capacity that is substantially less than an average absorption capacity of said liquid-absorbing section. - View Dependent Claims (28, 29)
