Quick answers
How much can it absorb?
Depending on the style, our underwear absorbs the equivalent of 3–6 super tampons (15–50ml). The High-Waist and Boyshorts offer maximum absorption for heavy flows and overnight wear.
Can I really wear them for 12 hours?
Yes. Our 3-layer LeakProof™ system is engineered for all-day and all-night wear. For very heavy flows, we recommend changing every 8–10 hours.
How do I wash them?
Machine wash cold on a gentle cycle. Hang dry for best results. Do not use fabric softener, bleach, or dryer sheets — they clog the absorbent layers. With proper care, each pair lasts 5–7 years.
Will they feel bulky?
Not at all. Our absorbent core is less than 2mm thin — that’s thinner than a panty liner. No diaper effect, no visible lines under clothing.
What’s the return policy?
Your first pair is completely risk-free for 30 days. Wear them, wash them, see how they work for your body. If they’re not right, we’ll refund your first pair — no questions asked.
Are they eco-friendly?
Each pair replaces over 2,500 disposable products over its 5–7 year lifespan. Our fabrics are OEKO-TEX certified (no harmful chemicals) and our packaging is recyclable.
THE SWITCH
Your period, without the extras.
Pads and tampons
- Changing every few hours, and planning your day around it
- Bulk, shifting and that diaper feeling
- A backup pad at night, just in case
- A new box to buy every single month
Blinx period underwear
- Up to 12 hours of protection in one pair
- Less than 2mm thin, invisible under clothes
- Sleep in any position, no backup needed
- Wash, dry, wear again for 5–7 years
THE SAFER SWITCH
Stop putting chemicals and cotton plugs inside your body.
A tampon sits inside you for up to 8 hours. A disposable pad is mostly plastic, glue and absorbent gel pressed against your most sensitive skin, every month, for decades. Blinx protects you from the outside, in certified fabric, with nothing left behind.
- Zero tampon TSS worry
Nothing goes inside you, so there is nothing to forget, nothing to change at 3am, and no tampon-related toxic shock risk.
- No plastic, no glue, no perfume
OEKO-TEX certified fabric, tested for harmful substances. No bleach, no fragrance, no adhesive strip against your skin.
- Breathes like real underwear
Pads trap heat and moisture. Our layers let air through and lock fluid away, so you stay dry, fresh and odor-free.
- No more rashes from pad edges
No wings, no sticky edges, nothing bunching or rubbing when you sit, run or sleep.
EVERY DAY. EVERY FLOW.
Pads and tampons run your day. This doesn’t.
Up to 12 hours of patented leak protection. Put it on in the morning and forget your period until bedtime.
Busy days
Back-to-back meetings, school runs, a long commute. Up to 12 hours, zero bathroom dashes.
Heavy nights
Sleep on your back, side or stomach. The High-Waist holds up to 6 tampons’ worth. Clean sheets, guaranteed.
Workouts
Squats, yoga, running. It moves with you, stays put and never shows a line.
Light days
Spotting, the last day, backup for a cup. The Thong and Seamless feel like nothing at all.
LEAKPROOF TECHNOLOGY™
3 layers. 2mm thin. Zero leaks.
Our patented 3-layer system was engineered to replace every disposable product in your life. A moisture-wicking top layer, an ultra-absorbent core, and a waterproof barrier — all in a fabric thinner than a panty liner.
- 12h leak-free protection
Absorbs up to 6 super tampons worth of liquid. Day and night, no compromises.
- Less than 2mm thin
Thinner than a panty liner. Zero bulk, zero diaper effect. Invisible under any outfit.

Machine washable, lasts 5-7 years. One pair saves hundreds of pads and tampons from landfill.
HOW TO USE IT
As simple as regular underwear
Wear
Put them on like any other underwear. No pad, no liner, nothing to insert. Wear them for up to 12 hours, day or night.
Wash
Machine wash cold on a gentle cycle. Skip the fabric softener and bleach: they clog the absorbent layers.
Hang dry, wear again
Hang them to dry, no tumble dryer. With proper care, each pair lasts 5–7 years.
REAL REVIEWS
Trusted by 1.5M+ Women
I was skeptical — another period underwear brand making big promises. But these actually deliver. Zero wetness, zero discomfort. I went on a boat trip and had absolutely no issues. Game changer.
The freedom of not needing a pad on top of underwear — I can’t even describe it. I sleep so much better now. Any position, zero stress. I bought the 6-pack and I’m never going back to disposables.
COMFORTABLE and ultra absorbent. Less than 2mm thick and nobody can tell. I almost forget I’m on my period when I wear them. These should be the standard, not the exception.
I love that they look like real lingerie, not medical underwear. The seamless ones are invisible under my work pants. Plus, knowing I’m replacing 2,500 disposable products? That feels good.
The Marianne lace is so elegant. My husband didn’t even realize it was period underwear. That’s the whole point — protection that doesn’t compromise on style.
REAL WOMEN. REAL FREEDOM.

THE SCIENCE
How does it work?
Our patented LeakProof™ technology uses 3 ultra-thin layers that work together — all in less than 2mm of fabric. Thinner than a panty liner, more absorbent than 6 tampons.
- Layer 1 — Draining
The inner layer wicks moisture away from your skin instantly. You stay dry to the touch, even on heavy days.
- Layer 2 — Absorbent Core
Our ultra-thin absorbent core locks in up to 50ml (6 super tampons). No odor, no wetness, no bulk.
- Layer 3 — Waterproof Barrier
The outer waterproof layer ensures zero leaks. Nothing gets through to your clothes. Guaranteed.

GOT QUESTIONS?
Frequently Asked Questions
What size should I get?
We recommend ordering your normal underwear size. Our sizing runs XS–2XL. If you’re between sizes, size up for a more comfortable fit. The fabric has some stretch.
Can I use them for bladder leaks?
Absolutely. Many of our customers wear Blinx for light bladder leaks (stress incontinence), postpartum recovery, and everyday discharge — not just periods.
How many pairs do I need?
We recommend at least 3 pairs for a full cycle rotation (wear, wash, dry). A 6-pack gives you a full week of coverage with room to spare. Most customers start with a 3-pack and come back for more.
Do they really not smell?
Our absorbent core neutralizes odor on contact. Customers consistently report zero odor even after 10+ hours of wear. The antimicrobial treatment keeps bacteria at bay.
Which style is best for heavy flow?
The High-Waist and Boyshorts offer maximum absorption (up to 50ml / 6 super tampons). They have the widest gusset and highest coverage. For overnight, we especially recommend the Boyshorts.
Can teens wear them?
Yes! Many parents buy Blinx for their daughters’ first periods. They’re easier and less intimidating than tampons, more comfortable than pads, and our XS fits most teens.
How long do they take to dry?
Hang drying takes 12–24 hours depending on humidity. For faster drying, lay flat on a towel. Do not tumble dry — heat damages the waterproof layer.
How much is shipping?
Standard tracked shipping is $3.95 and free on orders over $50. Delivery times and countries are listed in our shipping policy.
