PERIOD BIKINI

Your period isn't the problem.
Managing it is.

Most women don't realise how much mental energy their period takes up until they stop using pads and tampons. No more checking. No more planning. No more 3am sheet checks. Here's what makes Conturve different from every other pair on the market.

  • Surface dries in under three seconds. No wet feeling. No dampness.
  • Gusset reaches the rear waistband — the only bikini cut that covers you fully
  • 0 PFAS across 40 substances — full lab report searchable before delivery.
  • £22.99 once. Cheaper than four months of tampons.

"I was convinced I'd feel wet and uncomfortable the whole time. I felt nothing. I forgot I was wearing them by lunchtime. I've thrown away my last box of tampons."

Managing your period takes up more of your life than it should.

You have a drawer of clothes you only wear on your period.

Darker. Safer. Just in case.

You're scared to start your cycle on a work day.

Because you know what heavy days look like. And you're not near a bathroom every hour.

You've ruined things. More than once.

Underwear. Sheets. That one pair of trousers. Products that were supposedly "super absorbent."

Your pad won't stay put.

It shifts. It bunches. You spend half the day readjusting and hoping nobody notices.

You avoid things when you're on.

Certain plans. Certain outfits. Certain situations. You don't even think about it anymore. You just do it.

You woke up at 3am and checked.

And you'll do it again next month.

None of that is the cost of having a period. It's the cost of products that were never built well enough.

You've probably already heard of period pants.

You've probably already heard of period pants. You've probably already heard of period pants.

You've probably already heard of period pants.

Maybe you tried a pair. Maybe they leaked.

Maybe they felt like a nappy. Maybe you just never trusted them enough to wear them without a tampon as backup.

That's not you being difficult. That's the product not being good enough.

The ones that leaked did so for a specific reason — the absorbent panel stopped at the thigh. So when you sat down, turned over in the night, or stood up quickly, there was nothing covering the back. The fluid had somewhere to go. It went there.

The ones that felt bulky were built with outdated materials — thick, slow-absorbing, damp against the skin. The kind that made you feel like you'd traded one problem for a worse one.

So you went back to tampons. Or you kept using both. Because nothing actually solved it.

That's what we built Conturve to fix.

GUSSET DIAGRAM

Why your last pair leaked.

It wasn't the flow. It wasn't how you slept. It was this.

STANDARD BIKINI CUT

Gusset ends at the thigh

The lining stops before your waistband. So when you sit, sleep on your side, or stand up - the back isn't covered.

CONTURVE COVERLINE GUSSET™

Gusset reaches the rear waistband

Full rear coverage. Tested across 1,200 positions. Zero rear exposure detected in any of them.

Every standard bikini cut gusset stops at the thigh. The CoverLine Gusset™ doesn't.

Absorbency by level — tested with real blood, not saline.

Most brands test absorbency with saline — which absorbs 3x faster than blood. Their numbers look good in a lab. Yours is the body they didn't test for.

The gusset covers you fully. Here's how much it can hold.

Here's what the CoverLine Gusset™ actually holds.

Why the gap? Standard labs test with saline, which absorbs 3x faster than blood. The gap between label and real life is an industry-wide testing problem — not your flow.

Three layers. One simple job.

Conturve period pants work exactly the way a good product should — you put them on, they do their job, you forget they're there.

01

Gone in 3 seconds

The first layer pulls moisture away from your skin the moment it hits. Not slowly absorbed — actively moved away. That's why there's no wet feeling.

02

Locked in. Stays there.

The second layer holds the fluid so it can't travel back to your skin or outward to your clothes — even when you sit, move, or sleep.

03

Nothing gets through.

The third is a sealed barrier. Not water-resistant. Not "moisture-wicking." Sealed. Your clothes stay dry. That's the whole point.

The Questions We Actually Get Asked.

Three questions every first-time buyer asks. Three specific answers.

01

REAR COVERAGE

"Will it actually stay in place all day?"

1,200 positions tested. Squats. Lunges. Extended sitting. Sleeping on your side. The CoverLine Gusset™ held position in every one.

Zero rear exposure in any of 1,200 positions

02

ABSORBENCY

"How do I know the absorbency number is real?"

Most brands test with saline. It absorbs 3x faster than blood - so their numbers look bigger than they are. We test with fluid matched to real blood viscosity. The number on the label is what you get on your heaviest day.

What the label says is what you get

03

PFAS SAFETY

"Is it safe against my skin?"

PFAS have been found in competitor period pants - linked to hormonal disruption, added without disclosure. Every Conturve batch is tested across 40 substances under EPA Method 537.1.

0 PFAS detected - 40 substances, every batch

Transformation

The numbers are one thing. Here's what
the switch actually feels like.

First wear

You put them on. By mid-morning you haven't thought about it once. That's new.

DAY FIVE

You wore them overnight. You turned over. You woke up and checked out of habit. Nothing had happened.

WEEK 3

Your cycle comes around. You reach for Conturve. The tampon box is still in the cupboard. You just haven't needed it.

TIP: No tape measure?
You can measure yourself with a belt or dressing gown cord and a 30cm ruler! Tie the belt around your hips, place a piece of tape or pinch where it reaches, then lay flat and carefully use the ruler to measure the length

    The questions worth asking.

    I've never tried period pants. Will they feel wet?

    No. The inner layer moves moisture away from your skin in under three seconds. The surface stays dry. Most first-time buyers say this is the thing that surprises them most.

    How do I know how much they actually absorb?

    Because we test with real blood viscosity — not saline, which absorbs three times faster and inflates lab numbers. What's on the label is what you get on your heaviest day.

    I've read that some period pants contain harmful chemicals. Is that true for these?

    No. Every batch is independently tested across 40 substances under EPA Method 537.1. Zero PFAS detected. The full lab report is searchable before your order arrives.

    I'm worried about them leaking. I already trust tampons.

    Most leaks happen because the gusset stops at the thigh. Ours doesn't. The CoverLine Gusset™ runs all the way to the rear waistband — tested across 1,200 positions, zero rear exposure detected in any of them.

    How do I wash them? Is it complicated?

    Rinse in cold water after wear, machine wash at 30°C, air dry. That's it.

    What if I try them and don't get on with them?

    60-day guarantee. If they leak, full refund — no returns needed.

    You've been doing it the hard way for long enough.

    There always was an easier way.

    Buying the same products every month. Carrying backup. Planning what you wear. None of that is the cost of having a period. The tampon has been the default for forty years. It doesn't have to be yours. The switch takes one cycle. You'll know by day three.

    Eighty-nine per cent of first-time buyers stopped buying disposables within two cycles. Not because they were told to. Because they didn't need them anymore.
