Worried about leaks? You’re not alone.

Leaks are the #1 reason people stress about their period. At school, overnight, or just getting through the day.

Stop worrying about:

• Leaking overnight

• Leaking through clothes

• Constantly checking “just in case”

• Wearing backups on backups

It’s underwear first, protection second. Not bulky. Not stiff.

Just put it on and sleep normally.

• Front-to-back coverage

• No bunching or shifting

• Designed for side, back, and stomach sleepers

The Kt Sleepover Boxer looks just like regular boxers. Discreet protection you can count on!

Try Overnight Protection

The questions you are thinking, answered.

Is KT underwear bulky?

Is it hard to wash?

Is it actually convenient?

Is it just for backup protection?

They can be worn on their own or paired with other products like pads, tampons, or cups, depending on what feels best.

The key is finding the absorbency level that matches your needs.

Since no two periods look the same, and flows can change from day to day, having a few absorbency options on hand helps create a routine that works throughout the whole cycle.

Can I try and return it?

First Pair Risk-Free Policy:

Because they’re, well, underwear, we can’t accept exchanges or returns on used items. BUT you can try one pair from your first order risk-free for 30 days!

If you ordered the wrong size of period underwear, we’ll send you a different pair at no cost or offer you a standard refund within 30 days of delivery (excluding original shipping fees).

If your order included multiple period underwear, we ask that you only open, wash, and wear one pair of underwear. That way if you don’t love them, any unopened packages from the same purchase will be eligible for an exchange or a standard refund (excluding original shipping fees).

All unopened packages will be donated to local organizations to support people in need.

What if I haven't gotten my period yet?
