New ProLite XSmall arrived today. 8.2 ounces. Spec is 8 ounces. "Store weight" (the pad with plastic wrapper and enclosed booklet) was 8.8 ounces.
The die cut open spaces seem much larger than the those of the previous generation Prolite 3 pad. The fabric of the new Prolite is noticeably more transulcent; when holding each pad up to the light, the die cut open spaces in the new ProLite are much more clearly visible than the previous generation Prolite 3.
