So, full disclosure, I’m not a teen. I’m 32 but like to use period panties instead of panty liners when I wear tampons.
1. The description says ‘light flow’ and that is accurate. I would say this absorbency would hold a panty liners worth of flow, TOPS! Which is fine, it’s advertised as light flow!
2. It really IS seamless!!! I wear soft material scrubs for work, the kind of material that tends to cling, and you can NOT tell that I have them on! Many period panties have a think dram around the thigh/groin but these don’t!!
TLDR: I will buy again when it’s time to replace the ones I have now! And they are true to size. I wear a L/7 everywhere I buy underwear, the large is perfect for me

Kt by Knix for Teens Underwear FAQs
Kt by Knix is designed for smaller and growing bodies to fit teens. Kt Period Underwear are available in teen sizes with smaller leg openings.
Super Absorbency
Absorbs 9–12 tsp (45–60 ml) of blood—that’s about 9–12 regular tampons or pads! Perfect for overnight protection or your teens heaviest days when changing into a fresh pair might not be convenient.
High Absorbency
Absorbs 4–8 tsp (20–40 ml) of blood, or the equivalent of 4–8 tampons or pads. These are perfect for heavy flow days.
Medium Absorbency
Absorbs up to 3 tsp (15 ml), or about 3 tampons or pads worth of blood. Ideal for light to medium flow days or as backup to tampons or period cups.
All of our period underwear, swimwear, reusable pads, and activewear have our patented leakproof technology built right in.
First Layer: Wicks away sweat and moisture while neutralizing odors to keep your teen fresh all day long.
Second Layer: A super thin, highly absorbent liner that holds the power of 3–20 tampons or pads.
Third Layer: A secure, liquid-resistant outer layer keeps leaks from happening.
The short answer: nope! Depending on the absorbency level of the period underwear and the heaviness of your teens flow, your teen can wear our period undies on their own or as a backup to tampons or menstrual cups. They can wear our High and Super absorbency underwear alone and be totally protected, while our Medium absorbency underwear can be worn alone on lighter days or as backup on heavier days.
