So yes, I was a little nervous trying these out, but loved the idea of a zero-waste period, so gave them a go. Super impressed by them. I felt happy that there was no odour or squelchiness on my heaviest days. They are super easy to use and wash. I had two pairs, so made sure I could rotate between washing and wearing. I reckon x 4 pairs will cover a 5 day period safely. I would rinse out in the shower then throw them in a regular wash. I wore them overnight with a heavy flow and no leakage. For Eva Brief I would recommend going up a size! I\'m a size 10-12 would usually choose the Large. But I went up to the Xtra Large size based on other \"word of mouth\" and online recommendations. These were comfortable for me, so I think the Large would have felt too tight. So yes, thank you AWWA, these are great.
