I love the entire U by Kotex range. Not only is it affordable, but they are also colourful (lol) and do the job well.
The U by Kotex Ultra Thins are great as they have good absorbency, but don't make you feel bulky and self conscious about wearing a pad and thinking that everyone can see it.
These are a pretty standard pad - though I love that they have different patterns on the wings and the colourful packs. They are comfy and not at all bulky.
However, I find them hard to remove easily and in one piece and it annoys me that the piece of paper on the back of the wing peels off when you open them, which means the wings can get stuck together. This is annoying enough that I prefer other brands over these.
