Runs small
Child sizes. Size up. My teen usually wears xs/sm & the small was too tight on my petite 105 lb 17 year old.

Not designed to last
Bought 3. Washed before first wear. All 3 fell apart in washer after first use.

The product works great but does not hold up.
I like these a lot but they dont hold up very well. I have owned several pairs and they all tear at the seam. It is very frustrating. They do not hold up.

Ehh
Okay, doesn’t have much of the padding in the back and I can tell may be a problem for leaks especially overnight

Great for using with cups/discs
The Teen line definitely runs smaller. Teen large fits more like a women’s medium. Overall these are great to have while trying period cups and discs! Heavy flow days I’d use with a period cup. Lighter flow days just the underwear. Easy to wash too. I wish there were more styles and fits to purchase.

Only for children
I’m not sure why the sizing is so different for teen vs adult, I’ve been the same size when I was 15 as I have been at 21. But point is it didn’t fit and I will need to return it. So make sure you purchase the regular ones unless you’re a child. Great product though. Works AMAZING

I didnt know a pair of underwear could change my life
I love these, so I’m going to right a list about all the good things about them. 1. Super Comfortable, feels like wearing regular underwear 2. Very absorbent, you dont have to worry about changing often because you can wear them all day. 3. Great for every day of your period, super absorbent for heavy days but also great and thin for light days Hope this helped

Wow!
[This review was collected as part of a promotion.] I am thrilled that there are now teen sized. Panties for the young girls who are just entering womanhood. These are very absorbent and comfortable and feel just like a regular pair of underpants. Perfect for a discrete time of the month.

Size difference
Note that the teen sizes are much smaller than the adult sizes

Great to keep on hand
[This review was collected as part of a promotion.] I use these Thinx panties for myself, and I was so excited to be able to have them for my preteen. They are great to keep in her backpack in case she gets her period early. They are discreet and look just like regular panties. She loves how they are thin and comfortable.

Lifesaver
[This review was collected as part of a promotion.] These are a lifesaver for pre-teens and teens. Their bodies are changing so quickly and these provide a sense of comfort that is hidden. No bulky pads to carry around. I will continue to buy for my daughter

Game changer!
These are amazing! Truly does not leak and such a great alternative to pads or if you have a heavy flow and need extra protection.

They work well!
[This review was collected as part of a promotion.] My daughter really likes the Thinx Teen Bikini Period underwear. They work well and she had no leaking. We would recommend these to anyone wanting to give the pads and tampons a break!

Great
[This review was collected as part of a promotion.] These are a great product and convenient for a younger female. They have a nice fit and aren’t super thick like others we have tried. Overall a great product we will continue purchasing.

Great for a teen!
[This review was collected as part of a promotion.] I wish these were an option when I was a teen! I got these for my daughter, and they have really been great. She feels more comfortable and confidant while on her period. They have been low maintenence to wash and care for. So thankful this generation of girls has more options!

Ok
[This review was collected as part of a promotion.] These are okay but my daughter said the material wasn’t as soft as other ones she had tried. They are super absorbent and do not leak, so they will still be used. They asked nicely.

Great feel!
[This review was collected as part of a promotion.] I was skeptical about using a product like this, but I was not disappointed. They feel great and do not have a heavy feel, for the most part comfortable. I think the only thing that would make them completely comfortable if they were underpants themselves.
