What an awesome product! I don't have much leakage but I wear pads to stop lanolin and other oils and creams from staining my bras and shirts. I tried bamboobies at first, but the heart shapes wrinkled up in my bra and after one wash they looked dingy and stained and matted. Plus, I only had two pairs! Please don't waste your money. These have a waterproof side that seems like it would hold in leaks way better than bamboobies. These are SO much more affordable, fit perfectly in my bra with no wrinkling (I'm about a 38C/ 36D now that I'm nursing), and wash so well! I take about two minutes before I wash them to put some dawn on the areas that have lanolin on them and rinse it off just to get more of the oils off, but I'd done the same with the bamboobies and they just didn't survive. Be sure to only wash them with like colors because, being made to absorb and hold onto liquid, they absorb the washing machine water and all the dyes that are in it, so they will turn colors if you wash them with a pair of jeans or other highly dyed item. They may show if you wear a very thin, unpadded bra, but any pad would. I wear a lightly padded, underwire free nursing bra and have no issue even under very thin shirts. The company is also extremely in touch with its customers and I'm sure would be a huge help in any sort of customer service issue you may have (I can't speak from experience because I haven't had any issues with the product). Thank you for making a comfy, affordable, and effective product!
