    Fit

    The fit was much better on these and the AI feature was very helpful in choosing a replacement for the looser fitting ones I first ordered. The return policy was incredible!

    Nice but sizing takes some patience

    I ordered light leakproof (3 pair) and was sent moderate. To be honest, it is not an issue as the leakproof is for light, infrequent bladder issues. I love the seamless, smooth design of these briefs. I had to experiment with sizing to get a proper fit. Originally ordered XXXL per the size chart and my measurements but briefs were too large and did not fit properly. I sized down one size for a much better fit (could probably even downsize one more) so I felt the size charts were off and not very helpful, thus the 4 stars. But I do love these briefs for the comfy, smooth, sleek fit and will order more now that sizing has been established. To be determined if they hold up long term. Considering the price, this was not an impulsive purchase for me .

    Not leakproof

    Was super excited to try these. I got them to keep in my work bag just in case I start my period at work. My flow has never been heavy, and I leak through these in less than 2 hours. Sometimes I don’t leak through, but when I wash them, the blood has gone through and stained the fabric.

    I wouldn’t recommend.
