I've been able to try these out for a couple of periods now. They are very comfortable! I tend to have lighter periods anyway and these by themselves have been perfectly adequate for my last few days on my period. I found that they do move around some, but that they stay put a little better with the boy short type of underwear. These are my first foray into reusable menstrual products so I was nervous to try them, but they are great! Highly recommend!
