Good morning Shannon, Thank you for your feedback. Providing our customers with a high quality product is very important to us. These pads may appear thinner in the center because of the designated rapid protection zone, but rest assured, the innovation is designed to absorb faster than our previous core design. Again, we are sorry to hear about your experience and we would like to obtain more information. If you have a moment, please call us at 888-301-0332 and have the package available for us to obtain lot code information.
