Who needs period swimwear?

  • Competition or squad swimming participants, allowing you to focus on training or a swim meet without having to worry about period leaks. 
  • Teen or tween girls with irregular periods or who are entering into puberty. Periods can arrive unexpectedly, and period-proof swimwear can help protect against those unexpected moments while swimming.

How does Period swimwear work? 

 Eco Period swimwear offers four layers of protection.

  • The outer fabric is water-resistant, preventing water from seeping into the swimsuit.
  • The second layer is made of leakproof fabric to prevent menstrual blood from escaping.
  • The middle layer is designed to absorb and contain menstrual blood, and
  • The top layer is made of moisture-wicking mesh that quickly dries once out of the water.

Fabric Composition: Recycled nylon outer fabric

When your swimwear arrive, try them on over your regular, clean underwear before use to check the fit. Make sure to give them a wash before your first wear to improve the absorption performance.

Then to use the swimwear, simply wear them like you would with any of your other swimwear.

Step 1 Wash your Eco Period swimwear before wearing / using them. This activates the EcoTech and primes it for use.

Step 2, After wearing, rinse in cold water until the blood/ fluids are mostly removed. You can do this in the shower to save water, but just do it before the water heats up past 30 degrees, as heat will set stains into the fabrics.

Step 3. Pop your swimwear into a delicates wash bag and into the washing machine on a cold wash. Use a liquid natural detergent.
No fabric softeners.

Step 4. Hang dry on the line outside. Line drying is best as it is kinder to the fabrics. Just don't leave them out on the line for days.

Eco Period swimwear should NEVER:

Be cleansed with harsh detergents (these abrade and break down clothes which shortens their effectiveness and lifespan)

Be cleansed with fabric softeners (it's like fabric cholesterol and blocks the pathways in the fabric through which the liquid travels)

Be bleached (bleach kills everything, need we say more)

Be dry cleaned (putting the products into such a harsh environment with or without the added chemicals is bad)

Be washed in very hot water (heat breaks down the fibres and natural compounds that make these products so effective.

Think your individual decisions won't make a difference?

Well, did you know more than 12 BILLION pads and tampons are thrown out every year worldwide? Let's break this down even further to see the impact you CAN make - the average woman alone uses 11,000 pads, tampons and panty liners in their lifetime. That’s a lot of landfill! It's time to make the switch to Eco Period, you won't look back.

How does Period Swimwear work?

Eco Period swimwear is designed with absorbent layers and moisture-wicking materials to manage menstrual flow. The absorbent layers trap and absorb menstrual fluid, keeping you comfortable while swimming, by ensuring no menstrual fluid leaks out. The outer fabric is water-resistant to prevent water from entering the gusset. No swelling in water and No tampons are required.


Eco Period offers beautifully crafted, quality period garments that are made to last, and are just as good for your body as they are for the environment.

We are passionate about making a difference through our products and hope to help you transition (or continue) your journey towards zero waste, eco and organic period solutions.
