“Unfortunately this didn't work for me. I have heavy flow and it bled through the lining on either side within an hour on my heavy day. I suggested to ModiBodi that perhaps they should have the absorbent part extend to the sides so that it doesn't bleed through. They replied that if you have 'surges', sometimes the absorbent padding takes some time to absorb the flow and it can spill to the sides. This isn't a great response to me, considering they advertise so much that they are 'no leak', surges are normal for a lot of women, and I bought an underwear that was designed specifically for heavy flow. They refunded me the cost of the pair since it was my first trial, but note that shipping costs are not refunded. Writing my experience so that other heavy-flow women are aware. It may be ok to use for light days, I haven't tried it yet.”
