Finding swimwear you can confidently wear on your period used to feel impossible — but modern leakproof period swimwear has completely changed that.
Whether you’re heading to the beach, swimming laps, or planning a pool day, the right pair will keep you comfortable, protected, and carefree throughout your cycle.
This guide explains exactly what to look for when buying period swimwear — including fit, absorbency, fabrics, and maintenance — so you can find your perfect match.
Period swimwear is made with multiple built-in absorbent and leakproof layers designed to trap menstrual flow while you swim — without swelling, leaking, or feeling bulky.
Unlike tampons or cups, it provides protection through absorbent gussets that lock moisture in while the outer fabric repels water.
Key components:
Top layer: moisture-wicking and quick-drying to keep you feeling dry
Middle layers: absorbent core that holds 1–2 tampons’ worth (depending on style)
Outer layer: leak-resistant and water-repellent
Light to medium flow protection; great for casual swimming or pairing with a rashie top.
Available in women and teens cuts/ sizes.
Offers extra coverage around the stomach and waist — ideal for those wanting more security or postpartum support. The classic black high waist are any easy choice.
The Miami swim bottoms are a limited release for this season. These feature moderate to heavy absorbency, high waist and a higher cut leg that is also adjustable with tie sides.
All-in-one confidence for school, training, or water sports; less chance of movement or leaks.
Available in teens racerback or a ladies racer style.
Designed with fuller coverage around the bottom and fun colours — perfect for younger swimmers navigating their first periods.
💡 Eco Period tip: Choose the same cut you’d normally feel most confident in — comfort and fit are key to preventing leaks.
| Absorbency Level | Suitable For | Recommended Styles |
|---|---|---|
| Medium Flow | Most swim days | High-waisted brief, Ladies and Teen bikini bottoms |
| Heavy Flow | Longer wear time and full protection | One-piece racerbacks, swim shorts |
If you have a heavier flow, choose the swim shorts or racerback swim styles or wear your period swimwear alongside a menstrual cup for extra security. You can also grab a twin pack so you can change through the day.
| Fabric | Feel | Benefit |
|---|---|---|
| Recycled Nylon / Spandex | Smooth, stretchy, durable | Sustainable choice, chlorine resistant |
| Polyester blends | Quick-drying, firm hold | Great for performance swimwear |
| Organic Cotton liners | Soft against skin | Breathable, less irritation |
Period swimwear should feel snug but not tight — the seal around the leg and waist prevents leaks.
Avoid sizing up; the absorbent gusset works best when fitted close to the body.
If between sizes, choose the smaller fit for swimming comfort.
For teens, check the size guide which includes a flat lay measurement, designed to measure your swimwear at home and check the comparison against our brand.
💡 Try them on dry before swimming to test fit. Also try on with underwear underneath so if they do not fit you can return for an exchange.
Rinse immediately after use in cold water until it runs clear.
Machine wash cold (no fabric softeners or bleach).
Air dry flat or hang — avoid dryers or direct sunlight on elastic.
Store flat and ensure fully dry before re-wearing.
Proper care can extend the life of your swimwear to 2–3 years of regular use.
Replace when:
The absorbent lining feels thinner or takes longer to dry.
The outer fabric loses elasticity.
Can you swim on your period without a tampon?
Yes. Leakproof swimwear is specifically designed for this purpose — perfect for teens or anyone avoiding internal products.
Will my period swimwear leak in the pool?
No, if correctly fitted. The outer layer repels external water and keeps menstrual fluid locked inside the absorbent layers.
Can you wear period swimwear all day?
Yes — for up to 6–8 hours depending on flow. Always rinse after swimming and change if needed.
Is period swimwear hygienic?
Absolutely. The antibacterial layers and quick-drying materials help prevent odour and bacteria build-up when cared for properly.
