KT by Knix period underwear is designed exclusively for teenagers to keep them comfortable and protected throughout their period. They have a variety of styles to pick from, and their undergarments have varying degrees of absorbency. The very absorbent ones can be worn alone, while the low and medium absorbency ones can be used with a pad or a tampon. They don’t leak, so you can wear them while you’re on the go.

Knix’s smaller sister, KT, was launched in 2017. Knixteen was created after Joanna Griffiths believed that teens needed their own space in the world of periods.

Knixteen is an underwear brand that provides confidence to young girls with their excellent collection of period underwear and kits. This Knixteen period underwear review examines the brand’s period pants to see how good they are and what makes them so popular.

Knixteen Overview

The brand believes that every teenager should be as happy and confident as possible, and they aim to help by:

Oversharing: We admire that the brand overshares; they feel that there are no taboo subjects, that there is never too much information, and that no topic is off limits. Their social media venues are open and honest, and they give a terrific platform for any youngster, no matter where they are in their path.

Protecting the environment: Additionally, the firm is looking for ways to offset its carbon footprint in addition to reusing products.

How Do Knixteen Period Undies Work?

Knixteen’s unique leakproof technology is embedded into their period underwear, swimwear, and athletic wear, giving users the confidence to get on with their day.

The first layer has a moisture-wicking, antibacterial technology that wicks away sweat and moisture while eliminating odors to keep you feeling fresh all day. The second layer is a super thin, highly absorbent liner that has the capacity of 3–20 tampons or pads. Finally, the third layer is a tight, liquid-resistant outer layer that prevents leakage.

Who Is Knixteen Period Underwear For?

If you’re looking for underwear for a teen, KT by Knix features attractive, comfy, and period-proof options. These underwear kits are designed specifically for smaller, growing bodies, as opposed to the usual Knix brand. KT period underwear is available in junior sizes with narrower leg openings.

Knixteen’s super leakproof sleepover shorts are the brand’s most absorbent nighttime underwear, with a larger gusset to combat period stains and leaks. In addition, the absorbent nighttime period shorts include an ultra-comfortable bum-covering style and the brand’s 3-layer leakproof technology. According to the company, the leakproof shorts can hold 12 tampons or pads worth of blood.

Knixteen Period Kit Review

Knixteen’s three best-selling styles are included in this 5-pair bundle. The package is ideal for teens who want varying amounts of protection during their cycle, from light days to heavy days and everything in between.

What’s included:

  • Two leakproof underwear in black and a limited edition color. Each pair absorbs the equivalent of 3 tampons or pads.
  • Two Super Leakproof Underwear in Black and Limited Edition Color—Each pair absorbs the equivalent of eight tampons or pads.
  • One Super Sleepover Short in Black absorbs the equivalent of 12 tampons or pads.
  • One reusable bag

I wish I had discovered this years ago. Even on my heaviest days, I’ve never had a leak while wearing these.

5 star review @knixteen

My daughter adores these pants and has entered the world of womanhood with ease and confidence! I’m grateful she has these as she navigates this new chapter in her life. I would recommend them to everyone.

Knixteen Period Swimwear Review

knixteen period underwear reviews, KT by Knix, Knixteen reviews, knixteen swimwear reviews

Period? No worries. These bottoms allow you to swim without fear of embarrassing leaks. Not only can you wear them confidently alone, but you can also wear them as backup protection with tampons and menstrual cups as they feature three levels of leakproof technology:

  • The first layer absorbs perspiration and moisture while odors are crushed.
  • The second layer can hold up to three pads or tampons of blood.
  • Its third layer is a liquid-resistant layer that keeps leaks at bay.

Other features include: a classic bikini cut, cheekier bum coverage, a wide crotch, and a really discreet liner. Additionally they provide UPF 50+ protection and are resistant to seawater and chlorine.

The concept of a period swim bottom appeals to us. However, the fit appears to be off. My daughter has both bikini and boyshort period undies that fit well. These bottoms have an extremely saggy fit. The narrow groin and very high cut in front and back provide very little cover. My tween finds them just too intimate to be comfortable.
