These are my favorite of the period underwear I've tried and I really like them. Firstly, I prefer boxer briefs for my regular underwear, so I was happy to see that style here. Secondly, cotton is way better in my opinion than other kinds that are a synthetic stretchy material. I didn't realize right away that the underwear themselves are absorbent and the added insert is for extra absorbency, so that was a nice realization. I had thought the only absorbent part was the insert. They are great for sleeping and just living in the world. You don't have to worry at all about leakage. After many years of leakage and worry with pads (I don't like tampons or other methods) these are a dream come true. Too bad they weren't invented earlier, but I'm glad they're around now. Lastly, they fit great (I'm plus size, about a 3x).
