As far as size, shape, and coverage these are great liners. The sticky backing covers the entire back to give a smooth adhesion. However, this doesn't prevent bunching up during physical activity. 'A' says she would not wear these to gym ever again.
Moisture absorption is fine but the plastic baking really traps humidity against the body making you feel very sweaty, which is not a comfortable thing.
Finally the surface of these is soft but with long term (day long) wear there is pilling on the surface, which is uncomfortable.
All in all I would say that for short term, low activity, or over night wear, these would be fine liners. Otherwise I would go with something else.
I received all products complimentary from Influenster.
