    Worth it

    I’m 22, 5’7 and weigh 120lbs. Up until now, I have been purchasing size Small on the Knix womens website. The M teen fits exactly the same and are SO much more cost effective. Bought the 5-pack of course! Hope to see more styles in the future (please make a Knixteen thong!)

    My daughter recently had a sleepover. Said without these, she would have stained the bed. Love them!

  • Hello, Knixteen bikini bottoms. Bye bye, period stress. Throw on a pair of these uber comfy, classic-cut period undies and focus on doing what you love, not worrying about what you don’t. A breathable panty so that you can breathe easy. You’ll love these cute period panties — the classic bikini style is SO easy to wear all day. 

    These briefs look and feel just like any bikini brief — but they’ve got a secret weapon hidden inside in the shape of super powerful moisture-wicking fabrics. Clever panties for a clever girl. This popular fit is a firm favorite — perfect for teens and tweens of all shapes and sizes.

    Plus, they absorb 1-3 teaspoons of blood (that’s the equivalent of 2 regular tampons!). They’re totally seamless (can we get a hallelujah for no VPL?). Their innovative leakproof design is built with teen menstruation in mind. 

    We especially love how these panties help you feel fresh and odor-free throughout your period. Period panties are great for girls as  they don’t itch, rub, or cut into your skin. The fabric helps wick away moisture and sweat, keeping you bacteria-free and fresh as a daisy. They’re also easy to clean — bye bye blood stains.

    Order your pair today, or surprise a teen with a gift they’ll love.


    Why they’re awesome:

    • Made with super soft LYCRA SPORT® fabric and carbon cotton (translation: you stay high and dry, instead of inundated with menstrual flow).
    • Our seamless design lets you say goodbye to underwear lines — these panties are a subtle period weapon (even in your favorite jeans).
    • ‘Oh-No’ Proof Technology™ (includes a super thin built-in panty liner that sucks up 1-3 tsp of moisture) — and it’s a lot more comfortable than a traditional liner that can slip and move around.
    • Moisture lock sides keep leaks in, making your periods less stressful.
    • No-stink technology fights odor and keeps fabric fresh.
    • Perfect for wearing to school, gym class, sleepovers, horseback riding – anywhere!
