Disposable Period Underwear
Not Over Your Sheets.
Not Your Mattress.
Not Your Clothes.
FlowGuard absorbs up to 4 pads worth of flow in as little as 5 seconds and stays dry for up to 12 hours, even on your heaviest night.
You Already Know How This Goes
Waking up to check the sheets before you even open your eyes. Scrubbing a stain out of the mattress before anyone sees it. Throwing another pair of pajamas in the wash, or in the trash.
Regular pads shift the second you roll over. Tampons were never built to keep up once the flow gets that heavy. Some nights you barely sleep because you are too busy worrying if this is the night it gets through.
How FlowGuard Actually Holds
A core that absorbs fast
Flow gets pulled in and locked away in as little as 5 seconds, so it cannot sit on the surface or shift when you move.
Leak guards on every edge
Raised guards line both legs for 360 degree leak protection, so nothing escapes out the sides even if you toss and turn all night.
A waistband that stays put
The 3X stretch waistband contours to your waist instead of digging in or rolling down, so nothing shifts while you sleep.
We poured water directly onto this one, on camera, more than once. This is what stayed dry underneath.
What Changes Once You're Wearing It
- Sleep through your heaviest night without waking up to check the sheets
- Skip the tampon at bedtime entirely
- Wear it through postpartum recovery, not just your period
- Toss it when you are done, no soaking, no washing
- Individually wrapped, so one fits discreetly in your bag

Questions Before You Order
Will this actually hold my heaviest flow?
Each pair holds up to 4 regular pads worth of flow and starts absorbing in as little as 5 seconds, so it is built for first day and overnight flow, not just the light days.
Is it actually leakproof or just better than a pad?
The core is lined with leak guards along both legs and a full wraparound waistband, so flow is contained on every side instead of just underneath you. We have tested it on camera by pouring water directly onto the core and it holds without leaking through.
Can I wear this instead of a tampon at night?
Yes. A lot of people wear FlowGuard specifically because they do not want anything inserted overnight. You put it on like underwear and take it off in the morning.
Is it okay for postpartum bleeding, not just my period?
Many people wear FlowGuard during postpartum recovery in addition to their period, since the flow and unpredictability are similar. If you have specific concerns about your recovery, check with your doctor, but the underwear itself works the same way either time.
What size should I order?
L-XL fits a waist between 27 and 46 inches. XXL fits a waist between 35 and 57 inches. If you are between sizes, size up for the most coverage.
What if it does not work out for me?
You have 90 days from delivery to decide. If it is not the right fit, send it back.
