Love em for daytime wear on days 2&3

I love mine! I just purchased my 3rd pair.I find these to be the most comfortable period underwear for day 2 & 3 ( IFKYK).The fit is accurate, maybe a tad on the slimmer side due to kind of a tummy slimming design. Not awesome if you’re uncomfortably bloated, but awesome for running errands with minimal of that excess fabric feeling, some other fits have.It’s nice to not feel like I’m wearing a diaper.I feel pretty safe moving around in them, but they aren’t for sleeping in.

Reliable Period Underwear for All-Day Confidence!

These period underwear are incredibly comfortable, plus-size friendly, and completely leak-proof. I use them both on their own and as a backup with other period products, and they’ve been reliable every time. I feel confident and worry-free wearing them throughout the day.

Visible padding lines

Cannot wear these with much since the line where the padding stops midway butt is super visible.

High quality and sits very high waist!

I got this thinx underwear for my partner and it took a while for her to use it but once she was able to get to it, she really liked it. They did fit her weird and she said they were super high waist which isn't what she was particularly used to but she was able to overcome that very quickly. She usually has a pad or tampon in addition to the underwear just as backup and staying hygienically clean but she stated that she has not experienced any problem with them yet and she definitely feels like they are very high quality and the fabric is a lot better than the other ones that she has.

Not for all body types

I settled on these after searching for such products and on recommendation of an acquaintance (even tho not all reviews here are good either). First the positives, they are well made, good coverage, silky outer layer allows smooth movement of clothes/sheets. I am a senior, 5'9", 185 lbs (I know, that there is part of the problem, lol).Problems (for me, but would not be for everyone, probably): they are cut too high on the sides, not French cut, but higher than I like so I feel as if I need to tug them down all the time. They seem to be made for women with slim hips/buttocks. The friend who recommended them is an apple shape--as opposed to my pear. For those of us who want "full coverage" across the lower half, these don't do it. The back panel wants to droop/pooch (makes me think of a diaper) out on the sides, which would be held in place by pants, but odd nevertheless. They are supposed to be high waist, but only come just above the navel, so I still want to hike them up all the time. I bought a size up, as opt for comfort these days. Maybe a smaller size would fit better, but they still would not provide the all round comfort for daily wear. I kept them, b/c primarily bought them for sleeping, and ok for that. All in all I wouldn't order these again, but they may be fine for others.
