How Period Underwear Works

Designed to
Deal with All the
Annoying Stuff.

none

Shut Up,
Period.

Knixteen ‘Oh-No’ Proof Technology™ is like having a really thin panty liner built right in, saving you and your pants from life-ruining leaks.

Bye Bye,
Stink.

Ever notice that Aunt Flo smells kind of funny? Our underwear has odor-crushing technology that keeps you feeling fresh.

See Ya,
Sweat.

Whether you’re powering through a big game, or you’ve got some unexpected wetness down there, Knixteen’s LYCRA SPORT® material is designed to soak up moisture and dry fast.

Get Lost,
Underwear
Lines.

If you can see your underwear through your pants, you may as well call them overwear. Knixteens are super thin and made seamless so underwear lines are a thing of the past.
