I was skeptical because the price seems too good to be true. I was happily wrong! These are the most comfortable ones I have tried so far, and I have tried several. Both in bigger named brands, and in smaller more generic types. I have seen several reviews saying they need to size up, and that’s probably true for most people. I do not have much of back end, and not huge legs either. Not small or “thin”, but right in the middle. They do have quite a bit of stretch to them on the sides, but magically stay put and don’t move or shift in the padded areas. I am on average a US size 16, and I have purchased a L, an XL and an XXL, and I think the L and XL are perfect for me. The XL for the first couple of bloated days, and the L for the last bit. I do wear them in conjunction with a cup or disc during the first few days. Then just the underwear and have not had any leaks. I machine wash on delicate and air dry. I would say it takes about 2 full days to be fully dry, so you need a few days worth in a rotation to be able to use only these. Worth it for me!
