Tired of your period controlling you?

Every month it’s the same story. You wake up anxious, wear dark clothes “just in case,” double up on protection, and still spend the day terrified of that dreaded leak.

Tampons are uncomfortable. Pads feel like a diaper. And the mental load of managing your period around your life? Exhausting.

You deserve better. And now you have it.

  • Waking up to ruined sheets and ruined mornings
  • Constant pad adjustments and discomfort all day
  • Anxiety about leaking at work, gym, or social events
  • Expensive disposables that harm your body and the planet

I was honestly skeptical, but these have completely changed my period routine. Perfect for my first few days — holds everything without feeling bulky. I wear them at night and haven’t had a single issue. For a size 42 jean, the XL fits perfectly.

★★★★★

I’ve spent years feeling like period products weren’t made for my body. These changed that. The fit is perfect — no digging, no rolling, no anxiety. I wore them through a full work day and for the first time ever, my period was just… background noise. I actually cried a little when I realised how much mental energy I’d been wasting every month.

✓ All-day comfort

I bought three pairs and I’m going back for more. The quality is way better than I expected for the price. Soft, stretchy, true to size. I’ve washed them multiple times and they still feel brand new. Complete game-changer.

✓ Excellent durability

I have heavy flow and these handle my moderate days so well. On my heaviest day I pair them with a cup, but on days 3–5? Just these alone. No leaks. No anxiety. I genuinely feel like a different person during my period now.

★★★★★

I used to set a 3am alarm during my period just to check for leaks. Every single month. I didn’t even realise how normalised that was until I tried these and slept through the night for the first time in years. Woke up completely dry, completely calm. I genuinely didn’t know periods could feel like this. These aren’t just underwear — they gave me my sleep back. Fast delivery too, arrived in 5 days!

✓ Overnight use

Got questions?

Everything you need to know

How much can FlowGuard™ actually absorb? +

FlowGuard™ absorbs the equivalent of 3–4 regular tampons worth of flow. They are ideal for light-to-moderate flow days, overnight use, or as backup protection on heavier days. For very heavy flow, we recommend pairing with a menstrual cup on your first 1–2 days.

Will I feel wet while wearing them? +

No. The moisture-wicking top layer pulls fluid away from your skin and locks it into the absorbency core. Your skin stays dry throughout wear. Most customers say they feel completely normal — just like wearing regular underwear.

How do I wash them? +

Rinse them under cold water after use until the water runs clear, then machine wash on a gentle cycle in cold water. Do not use fabric softener — it reduces absorbency. Lay flat or hang to air dry. Do not tumble dry on high heat.

How do I choose my size? +

Our sizing runs: S (US 4, ~40–50 kg), M (US 6, ~45–55 kg), L (US 8, ~50–60 kg), XL (US 10, ~55–65 kg), XXL (US 12, ~65–75 kg), XXXL (US 14, ~75–85 kg). If you’re between sizes, we recommend sizing up for maximum comfort and coverage.

Can I wear them at night? +

Absolutely — many of our customers primarily buy them for overnight use. The leak-proof barrier layer ensures nothing escapes, and the soft fabric means you’ll sleep comfortably without any awareness of wearing protection.

Are they suitable for incontinence? +

Yes! Many customers also use FlowGuard™ for light incontinence, post-partum discharge, and daily spotting. They are discreet, comfortable, and highly effective for light-to-moderate fluid management of any kind.

Will they smell after a few hours of wear? +

No. The inner layer is designed with odour-neutralising technology that actively traps and eliminates odour throughout the day. Most women report feeling completely fresh even after 8–10 hours of wear. The key is rinsing them promptly after removal.

Can I wear them with a heavy flow without backup? +

FlowGuard™ handles light to moderate flow confidently on its own. For very heavy flow days (day 1–2), we recommend pairing with a menstrual cup or tampon for extra security. From day 3 onwards, most women with heavy flow use them alone without any issues.

Do they feel wet or soggy when full? +

The moisture-wicking top layer keeps your skin dry even when the absorbency core is holding fluid. You won’t feel wet against your skin. However, like any absorbent product, we recommend changing them every 8–12 hours or when you feel the need.

Can I wear them during sex? +

FlowGuard™ period underwear is not designed for penetrative sex. However, many women wear them during their period for added confidence and comfort during intimate moments, removing them when needed. They’re great for that in-between peace of mind.

Will they stain permanently? +

The dark inner lining is specifically designed to minimize visible staining. For best results, rinse in cold water immediately after use — never hot water, as heat sets stains. Machine wash on a gentle cycle. With proper care, they maintain their appearance wash after wash.

Are they safe for sensitive skin or allergies? +

Yes — FlowGuard™ is made from hypoallergenic cotton-blend fabric free from harsh chemicals, dyes, and fragrances in the skin-contact layer. They are suitable for sensitive skin, eczema-prone skin, and women who react to conventional pads or tampons. If you have a known latex allergy, you’re safe — there’s no latex used.

How do I know when they need to be changed? +

Unlike pads, there’s no visible indicator. We recommend changing every 8–12 hours as a general rule. On heavier days, you may feel a slight warmth or fullness sensation — that’s your cue. Most women develop a natural routine after the first cycle of use.

Can I swim or exercise in them? +

FlowGuard™ swimwear is undergoing intensive research into the most cutting edge designs for swimming — but for now, water pressure may still saturate the layers. However, they are perfect for all land-based exercise including running, yoga, gym workouts, and cycling. The flexible fabric moves with your body and the leak-proof barrier holds firm during any workout.
