The pad area is thick like a diaper. It's also super warm, and it takes over 24 hours to air dry. They are very absorbent, and the pad area comes high up on the front and far enough at the back. The thickness does bring some security in that there is a lot of material to absorb the flow, but they aren't the most comfortable panties capable of the same.
My waist size is 92cm, and despite the S size going up to 96cm they were a bit snug at first. They have the Ameissy logo on the front which isn't present in the marketing photos. The panties have no tags which is nice, but the seam with the see through material is a bit itchy to me.
