Period Swimwear

This year seemed to have been the year of the period underwear. Brands all over the market, across all different price points, created period underwear within the last few years, proving this is a product here to stay! Period underwear is underwear made out of material that will absorb your period blood, ranging from 1-3 tampons worth, depending on the cut and brand of the underpants. Recently I saw that period swimwear is now on the market as well. 

This surprised me and raised a lot of questions. How on earth could these still be absorbent when they’re submerged in water? What if my swimsuit gets knocked out of place slightly while I’m swimming or frolicking in the ocean? Lucky for you, dear reader, I investigated a bit and have some answers.

How does period swimwear work?

In doing my research, I found that Ruby Love and Knix were the two most popular brands making period-proof swimwear at the moment. Both brands, and period swimwear in general, use the same technology to absorb blood that period underwear does. Ruby Love had an informative video and diagram on their website showing the layers of fabric they use to absorb blood, but no specific info on how much blood their swimwear could absorb. Knix, also known for making bras and underwear outside of the menstrual care game, is a little more specific. Their website says their period swimwear holds up to three teaspoons, or two tampons worth of blood. 

At first I thought this didn’t sound like a lot of absorbency, but then I remembered we’re just talking swimwear here. If you were to go to the pool or the beach, you probably wouldn’t use more than two tampons anyway, depending on how long you’re there and how heavy your flow is, of course. 

What if I need additional protection?

Both websites also suggest that you can use the period swimwear as a little backup protection, wearing them with a menstrual cup or tampon, or you could wear it solo, relying only on the swimwear to manage your period alone. Of course, every person’s body and menstrual flow is different, so I’d advise wearing this swimwear on your lightest days at first, or using a tampon or menstrual cup with it as you’re getting used to the product. Although, if you’re already a fan of period underwear, and already know what days of your period you can confidently wear them and have no leaks, then you might as well give it a go. If you already have used Knix’s period underwear, for example, their swimwear would likely work exactly the same way.

Would you try period swimwear?

I love that we are making more and more strides in period management as each year passes, giving people a lot of options for their period care. I think I’d try the period swimwear perhaps on a light day on my period. I do have faith that this swimwear could absorb my period while I and my body are dry, but I don’t quite understand how it could keep that period blood locked in when I jump in the deep end. All of the information out there suggests period swimwear, no matter the brand, can do just that, so I’ll have to try it out myself.  Find more info on Ruby Love and Knix on their websites.
