I have used GooN, Pampers and Nepia. For my B (tall but slim, pat pat is not big), GooN and Pampers (紫色棉柔) are very good because they are longer in size. However, Nepia is not very suitable to him since it's too short.
Never try Unicharm and Merries before. May want to buy them in Japan. Any comment
-What's their size and length comparing to GooN and Pampers
-Comfortable
-Any wet indicator
