So far so good
So far so good. It's only been three months. We were told they absorb more the more you wash them, and that seems to be the case. They haven't leaked as far as I know. They're comfortable, soft and fit great on my teen. She hasn't complained.

Mom of a teen and preteen
As a mom of two preteen girls, finding period products that feel comfortable, reliable, and not embarrassing has been so important to me—and these period panties have honestly been a game changer for our household. My girls were nervous at first, but they immediately loved how these feel just like regular underwear. They’re soft, breathable, and not bulky at all, which made them much more confident wearing them to school and activities. From my perspective, I love the peace of mind. The absorbency is impressive—no leaks, no stains, and no panicked texts during the school day. They’ve been especially helpful for lighter days, overnight protection, and as backup on heavier days. Cleanup is easy too: rinse, wash, and reuse. It’s saved us money and reduced waste, which is a win as a parent. Most importantly, these have helped make periods feel less scary and more normal for my girls. Anything that gives them confidence and comfort during this stage of life is worth it, and I would absolutely recommend these to other moms navigating the preteen years. I’m still not sure I’d trust without added protection. Huge peace of mind for my girls that they won’t ever leak through.

Excellent quality!
Why did you pick this product vs others?: My daughter loves these. She just started and really wanted something with extra protection, just in case. We ordered a 12/14 at first. She is in a size 14, but pretty petite. They were so tiny. She thought they were way too tight and uncomfortable. They are a bikini style so if you can size up, they will probably fit better. We ordered a 14/16 and I thought they would be way too big (even after I took them out of the package they looked huge) BUT they fit her perfectly and she says they are so comfortable. She just went on a field trip to a farm and used these with her favorite pads out of the 3 brands we’ve tried this week. Pinkie tween/teen organic pads. She said of all she’s tried, including a well rated brand for starters, she still prefers these. “I don’t even feel like I’m wearing anything with the Pinkie ones-ANd they smell fresh of all of them!” Just so you know these panties are not meant to wear without a pad or tampon. They are double layered for a better protect protection and comparison to a regular panties. Again, you must wear a pad or a tampon while wearing these panties.

Brilliant idea!
Wish they had these when I was a kid! Bless the person who invented these! My 12 year old daughter just started her monthly and she knows that when it’s getting to be that time to put these on just in case. She also wears them while she is on with a pad for extra protection.

Not worth it, don’t recommend
I would say the only positive about these underwear is that they fit my 10 year-old very well. Otherwise, I will say that we ended up just throwing the entire pack away. She used quite a few pairs and we found that she ended up bleeding right through them and the underwear ended up staining on both sides of the fabric. I believe the point of period. Underwear is supposed to be that it protects you from bleeding through your underwear and onto your pants. This is not the case with these as they were bleeding through the fabric very easily. I would not recommend these. I did read back through the description and it does state that we should use sanitary, napkins, and tampons with this underwear. I should’ve done a better job reading it beforehand.

Thinx again
These are not a good knock off of the Thinx underwear. We originally started with those and my daughter loved them. They are just quite expensive so I decided to give these a try. First off, these run rather large compared to the Thinx brand. They are also extremely thin. My daughter can wear her Thinx on a heavy day for several hours with no issues. The first thing she said when she saw these was there was no way they'd work and she didn't want to wear them because she didn't trust them. We didn't the water test just to see. The water just leaked out the side and eventually soaked through the lining. They are going back and we will be paying extra for the real deal. You get what you pay for.
