fits to size
These are nice and do what they need to do. I disagree with those who say they run small and are hard to pull on. My daughter wears S and XS in women's size. She's slender and 5 ft 3'. I first got her a Medium, but they were too big on her (loose in the butt), and I had to exchange for XS which fit her just fine. Bonus points: this brand comes in many colors which she loved.

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.

Loved - but why are they “teens”?
These are great. I wanted colours, patterns but all were labelled “teen”. I thought maybe they were sized smaller than usual. I’m 46, a size 6 - they fit the same as any “adult” period undies (these aren’t my first - do size up in all period undies - they are snug on purpose and you will be bloated).

Great Period Underwear. Better Than Thinx
My preteen's favorite period underwear. The protective barrier stretches from the front waist band all the way to the back, which is the best for exercise and lying down. It is thin, not bulky, it does not make rustling sounds when walking. It looks like regular underwear with added protection for leaks. Of course you still have to use feminine hygiene products. These do not have the absorbency for free flowing, unless with really light flow at beginning of end of cycle. I'm comparing these to the expensive Thinx underwear which we bought before these. They were bulky, the barrier did not go from waist band to waist band, and they looked so old after a few washes. But the main issue with those was the bulk was noticeable through her jeans, and she experienced leaks in bed while sleeping and even leaks in public. These underwears don't have any of those problems and price is great. Also they're FSA eligible! For size reference 5'1", 115 to 120 lbs. Wears Medium in these.
