Leak-free, super-absorbent, designed to withstand ultra-movement and sweat.  Absorbs 8 to 10 tampons worth of flow!

Your favorite bikini can now do a marathon, a spin class, a barre class, you name it! Or I’m just great for a busy day of running around.  I’m currently the world champion in being waste-free and super-absorbent.

The Sporty. Bikini is made from our PeriodTech™ fabric - a super stretchy Nylon and Spandex knit that moves with you. As always, the gusset is made with organic cotton.

When To Wear: doing a marathon, going to the supermarket, and everything in between.

How do I wash and care for the Sporty Stretch Bikini?

Rinse it in cold water for a few seconds, then hand wash and hang dry or add it to your regular laundry. Use a regular wash with no bleach, tumble dry low or hang dry, and never dry clean it.

What is the Sporty Stretch Bikini made of?

The main fabric is PeriodTech, an 85% nylon and 15% spandex knit. The gusset lining is 95% organic cotton and 5% spandex, backed by a 100% polyester absorbent layer and a 100% polyester PUL leak resistant layer.

Will I feel wet wearing the Sporty Stretch Bikini?

It should not feel wet. The soft organic cotton lining sits over an absorbent layer that draws flow away from your skin, and a leak resistant layer stops it coming through. If it ever starts to feel damp, that is your sign to change.

Will the Sporty Stretch Bikini stain or stay stained?

Not if you rinse it in cold water soon after wearing it. Cold water lifts blood out before it sets, while hot water can fix a stain in place. Skip bleach, which breaks down the fabric, and wash on a regular cycle.

How much does the Sporty Stretch Bikini Period Underwear hold?

It absorbs 8 to 10 tampons worth of flow. It is made for heavy days and high movement.

Is the Sporty Stretch Bikini good for exercise?

Yes, it is designed to handle ultra movement and sweat, from a marathon to a trip to the supermarket. The PeriodTech nylon and spandex knit stretches with every move.

What colors does the Sporty Stretch Bikini Period Underwear come in?

It comes in Black, Rose, Cranberry, Terra, Blackberry, Moss, Citrus, Lilac and Plum. Sizes run XS to 4X, with availability varying by color.

Can I buy the Sporty Stretch Bikini outside the US?

No, not at the moment. It ships directly from The Period Company and is currently available to US customers only. It is also excluded from discounts and sales.
