Well you do not have keep to your period pants like normal. So I find that they fit in really easily with adjustable poppers. Much easier to get the right fit than the plastic type with sticky backing. When using the old fashioned type you can’t adjust the fit once you have stuck, with these you can. For me these are even better than the mass produced disposable ones. I don’t find I have too much movement once they are in place. The movement that I do have seems to go with my natural movement rather than against it. The other benefit is that I am silent for the day. No more rustling when I turn or even walk. So a good fit, with no leakages and a more breathable experience from the natural cotton. I was really relieved the first time as it really plays into my worst nightmare of periods. I hate the idea of being in the middle of work and needing to change my clothes because of an accident. These do manage to give me a better level of discretion and I feel confident with them already.
