The Deep Dive on Leakproof Period Swimwear

Whether we’re planning a vacation or just looking forward to a dip in the pool, most of us have had that sneaky little thought: What if I get my period? 

From there, panic and preparation ensues. Extra tampons are packed, a pair of emergency swim trunks are stashed away in our beach bags. And despite the hot weather, we suspiciously tell everyone, You know what? I actually don’t even feel like swimming today...

This is why we created Leakproof Period Swim. Gone are the days of dodging waves when you’re surfing the crimson one—we have you covered when it comes to swimming comfortably on your period. 

Read on to learn about how the Leakproof One-Piece worn by @rileyticotin helps provide confidence.

How does Period Swim work? What makes it different from Period Underwear? 

We’ve spent years perfecting our Leakproof Period Underwear, so we knew we had to adapt it for protective swimwear. Available in a Classic One-Piece and a High Rise Bikini Bottom, both have a super discreet absorbent pad in the liner that absorbs about 1-3 tsps of blood.

Depending on your flow, you can wear them on their own on lighter days or as a backup protection for extra confidence.

But how exactly does it work? The layers in the gusset of these bathers work to absorb your period. We added an outer layer of waterproof material for extra protection, which acts as the extra line of defense whether you’re treading water or running through the sprinkler.

But wait… I thought I didn’t leak in the water?

Although it may seem like it, your period doesn’t actually stop while you’re in the water. Instead, you might be experiencing a reduction of flow due to the water pressure. Your period is still happening, it’s just not flowing out of your body at the same rate. 

How do they lock in your period in the water but still get clean in the washing machine?

When Leakproof Swim goes in the wash with detergent, the absorbed blood releases during the wash cycle — leaving your swim fresh and clean for tomorrow's laps. Reminder: no bleach or softener, and lay flat to dry.

When should I wear them? 

It’s important to find what works for you. If your flow is light, or you’re at the end of your period, Leakproof Swim, on its own, may be enough protection for you. If your flow tends to be heavier or you're on day-one of your period, you likely want to pair your Period Swim with backup protection—like a tampon or menstrual cup.

Everyone’s period is different, and you know your flow best! PS. The absorbent pad is discreet, so you have the option to wear these when you're not on your period too. You can't even tell the High Rise Bottoms Deddeh Howard (@secretofdd) is wearing are Leakproof.

Where can I wear them? 

Where can’t you wear them is the better question! Wear them to the lake, at the beach, in the pool, chasing the kids through the sprinkler, and catching some rays in the backyard. Whether it’s a camping trip or a relaxing hot tub dip, they’re equally comfy in and out of the water.

How do I find my right size? 

Finding the right size is super important when it comes to Leakproof Swim, since you'll want your swimsuit to fit nice and snug in the legs and gusset to achieve the best protection.
