Love these to keep all baby essentials in. I use the biggest one for my portable breast pump and pieces ! Love the little ones to throw baby clothes in (clean or dirty ) .Love the range of sizes and the bright colors. They're great for our pool bag. But they aren't completely waterproof; if you put soaking stuff in them it will eventually seep through. Not a huge deal to us but worth knowing.I use these for my cloth pads. They are perfect for holding the pads until I am ready to wash them at the end of my cycle. They have been holding up well. I am very happy with them.These are fantastic little bags especially for a family that does swimI have purchased multiple sets of these and love them all! Perfect for packing day trip clothes, bottles, dirty laundry etc.
