The article of claim 1 wherein said pair of elasticized barrier layers is said pair of elasticized side barrier layers. 3. The article of claim 2 wherein: one of said first and second end segments of each of said first and second elasticized side barrier layers is attached to said topsheet along one of said proximal and distal ends of said absorbent layer; and the other of said first and second end segments of each of said first and second elasticized side barrier layers is attached to said topsheet along the other of said proximal and distal ends of said absorbent layer. 4. The article of claim 2 wherein one of said triangular elements of said first elasticized side barrier layer intersects and overlaps a laterally aligned one of said triangular elements of said second elasticized side barrier layers to form a double barrier layer on said top sheet along one of said proximal and distal lateral ends of said absorbent layer. 5. The article of claim 4 forming three double barrier layers. 6. The article of claim 2 wherein each of said triangular elements of said first elasticized side barrier layer intersects and overlaps a respective laterally aligned one of said triangular elements of said second elasticized side barrier layer to form a double barrier layer on said top sheet along each of said proximal and distal lateral ends of said absorbent layer. 7. The article of claim 6 forming four double barrier layers. 8. The article of claim 1 wherein said pair of elasticized barrier layers is said pair of elasticized end barrier layers. 9. The article of claim 2 wherein each of said generally triangular elements forms a generally right triangular element with the hypotenuse of said generally right triangular element being elasticized. 10. The article of claim 9 wherein only said hypotenuse of each said generally right triangular element is elasticized. 11. The article of claim 9 wherein said hypotenuses intercept and overlap each other at points spaced from both said longitudinal sides. 12. The article of claim 8 wherein the inner edges of said leg segments are elasticized. 13. The article of claim 12 wherein only said inner edges of said leg segments are elasticized. 14. The article of claim 8 wherein said inner edges of said leg segments intersect and overlap each other only at points spaced from both said longitudinal sides. 15. The article of claim 8 wherein the inner edges of said bight segments are elasticized and spaced from an adjacent one of said lateral ends. 16. The article of claim 1 wherein each of said elasticized barrier layers has an elasticized inner edge (i) defining a partially continuous configuration having a discontinuity therein, and (ii) extending for essentially its entire length non-parallel to said longitudinal axis. 17. The article of claim 1 wherein each of said elasticized barrier layers is a vapor-pervious nonwoven. 18.
