Great alternative to pads
Super comfy, not too thick! They fit perfectly and cover like my usual underwear does. I haven’t leaked yet and I have a moderate to heavy flow on average. No shrinking in the wash’s and the discharge washes right out, no lingering smell or stains that I can spot!

Work great
These were great. No leaks, comfortable ,durable stretchy. I was always scared of TSS with other feminine products. I’m so glad they made these.

Super comfy
Really comfortable and reliable underwear for periods. They fit well and don’t show under clothes. The leak protection works great, and I like that they’re washable and reusable. The only downside is they can feel a bit bulky sometimes, but overall a great product!

Kept me dry after water broke!
They fit as expected and boy are they absorbent. I can't attest to these as period panties just yet because I bought these while pregnant and my cycle still hasn't returned, but I trust them to be there for me when I do because they definitely proved their worth after my water broke! Obviously they couldn't take *all* of that fluid, but they at least got me to the hospital and through check in.

Worth the money
I wish I would’ve known about these years ago because they work well. My skin gets irritated from wearing a pad and having pcos means for me that my period last longer than most so these are great for giving my skin a break. They also work well if you have for light bladder leaks. The only thing I would change is I wish the protective coverage would go higher in the rear. They do take a little more care to clean and are pricey but well worth it and it saves on buying so many pads. Also if you wear tampons these would be great for a little extra protection.

Works great - most like regular undies!
These do a nice job - maybe not on heavy flow days, but I like them better than the bulkier Thinx ones. They seem more like regular 'brief' panties and aren't too thick in the absorbent areas.

Good Quality for lighter flows
I really wanted to love these, but they didn't fit my needs. The quality is great. They're very comfy and look nice. But they aren't designed for those of us with very heavy flows. Although they absorb well enough, there is risk of leaking on heavy flow days. This is because of the too-narrow crotch. I'm a tinier build than average and I still find the crotch too narrow. It would be fine if these were regular underwear and not during periods, but not for period underwear. I definitely had an embarrassing day that I had to leave work early because of leaking. That said, these are great for very light period days, spotting, and for those with concerns about awkward moments of mild incontinence. I still wear them, especially on those days when I'd like a little protection just in case my period starts earlier than anticipated. But definitely not for my medium and heavy flow days!

Caused Rawness/Irritation
I really wanted to love these. Now I wish I could get my money back. The quick reason is: Every time I wear them, my vulva gets extremely itchy, red, & raw, wear the absorbent portion of the underwear sits. I’m honestly so bummed because they are very comfortable otherwise. I’ll leave a breakdown below. COMFORT: Extremely comfortable. I got the regular absorbency & the underwear themselves are very comfortable. No underwear lines. Stretchy buttery soft fabric. The ABSORBENT PORTION is not bulky or uncomfortable. it’s bendable, moves with you, & there is no weird crunchy sound that people complain about with other brands. Downside- As mentioned above, Caused my vulva to become itchy, very red, & raw every time I wore them. I can no longer wear them because of this. I bought a 3 pack… so that’s a lot of money for something I can’t wear or sell/give away. SIZING: I recommend sizing up if you are normally between sizes. ABSORBENCY: I wore mine as a back up for my saalt period cup or disk. They absorbed nicely & kept me dry.
