Layer 1 — Instant-Dry Surface

The moment moisture hits, this top layer wicks it away from your skin and pulls it down into the core. No damp feeling, no irritation, just instant freshness. You won't feel a thing.

Layer 2 — High-Capacity Core

This is where the magic happens. The core absorbs up to a full cup of liquid and locks it deep inside, whether your flow is light or heavy. It absorbs multiple times its own weight, so you're covered all day without changing.

Layer 3 — 100% Leakproof Barrier

A fully waterproof membrane that seals everything in. Nothing reaches your clothes. Not a drop, not ever. This is the layer that separates PureFlow™ from products that claim to be leakproof but aren't.

Layer 4 — Premium Cotton Comfort

The outer layer is 80% premium cotton with enough stretch to move with your body. Soft, breathable, and flattering. It looks and feels like the underwear you already love.

Sleep without leakage

You know, when you take the risk of jumping in your comfiest pajamas before heading to bed, only to wake up the next day with both the pajamas and your sheets completely ruined.

You wake up sad, frustrated, and worried that you'll leak even more throughout the day.

And we know the feeling of having to use half of your only break to change tampons or having to empty and wash the icky stained cup.

Which is why we made PureFlow™, the period panties made for you to stay comfortable and completely worry-free.

Be confident, feel free

PureFlow™ is made to be 5x as comfortable as your favorite undies while absorbing 4x as much as a tampon with extra front-to-back coverage, just for the heavy-flowing girlies.

Plus, they're made of breathable bamboo fabric for you to stay completely odor-free for up to 9h+.

(PS. They also compress the belly for that tiny confidence boost)

WOW, these are something else!

I’ve tried both Thinx and Knix, and both failed me, especially at night. I honestly didn’t believe these would be any different. But I wore them on my heaviest night, and I woke up with zero leaks and zero stress. Best buy EVER! I’ve tried both Thinx and Knix, and both failed me, especially at night.

Thought they would stink...

My biggest fear was that the awful smell would spread. But these actually feel completely dry, and odor free, even after hours of wear. I finally feel confident being around people without second-guessing myself. My biggest fear was that the awful smell would spread. But these actually feel completely dry, and odor free, even...

I have a super super heavy flow

I have a really heavy flow, especially the first two days, and that’s when everything usually goes wrong. These gave me a level of control I’ve never had before. I can go hours without worrying, even during long workdays. I have a really heavy flow, especially the first two days, and that’s when everything usually goes wrong. These gave...

Thought I would hate them

I hate anything that feels bulky or diaper-like, so I avoided period underwear for years. These feel like normal underwear—soft, lightweight, and actually comfortable. I forget I’m even wearing them.

Perfect for teachers

I’m a teacher, so I can’t just leave class whenever I want. Before, I was constantly anxious during long lessons. Now I don’t even think about it, and I can get through the entire class without worrying about leaks. I’m a teacher, so I can’t just leave class whenever I want.

I shouldn't have hesitated

The quality is top-notch, and it's so breathable. I was initially hesitant to switch from my usual brand to this new one, but I'm so glad I did!...

FAQs

What if it doesn't charge properly?

We've engineered the charging system specifically to eliminate the finicky fit issues that plague other headlamps. If anything ever feels off, you'll get a free re-ship within 90 days.

How bright is it really?

350 Lumen, which is bright enough to light up your entire workspace, not just the spot you're staring at.

How long does the battery last?

8+ hours, which is long enough that you'll stop thinking about it. Most users cruise through full work sessions, late-night tasks, and everything in between on a single charge.

How do I charge it?

Plug in any USB-C cable—the same one already sitting on your desk. No proprietary chargers, no adapter hunting, no friction. Just top it off and get back to work.

Is it comfortable for long wear?

The flexible, featherlight band contours to your head without squeezing or shifting—you'll honestly forget it's there. No hotspots, no pressure, no mid-task adjustments. Just hours of distraction-free wear.

Can I turn off the motion sensor?

Completely your call. Flip between motion-sensor mode and manual control anytime, so the light behaves exactly how you want it in any situation. You're always in charge.

Is it worth the price compared to cheaper options?

Cheap headlamps are cheap for a reason—they dim, fail, and drain batteries faster than you'd expect. This is the light you buy once, use for years, and never have to replace mid-project at the worst possible moment. The math on that is easy.
