The Swim. Bikini
Built for swimming, absorbs 2 tampons worth of blood, perfect for pool and beach days.
Hello!! I am the Period. Swim Bikini!!! I do everything a normal great bikini does: I look good, and I’m soft and comfy, but I have two major differences. 1) I absorb period blood 2) while swimming. Whoah! I know that sounds pretty impressive. Here’s how it works. You slip me on, as you would regular swim bottoms, then head to the beach, the pool, or the lake. While you’re swimming, an incredibly sophisticated operation is going on: I am absorbing all your period blood on the inside of the underwear, while keeping out the water on the outside, so you don’t have that baggy feeling. Imagine never leaking again on the beach, imagine never leaving the pool to change your tampon, imagine never ever having to worry about coming out of the pool or the ocean with a tampon string hanging out - you know that moment - well it’s over. Stop imagining and start realizing! Period. Swim is here. The only problem you’ll have with me is working out what bikini top will go well with me. Here’s a hint: all of them.
A few notes about our Period. Swimwear:
It’s normal for the garment to fit snug when dry. It will relax and grow about half a size when wet.
Our crotch liner is non toxic, but can leave a residue when taken off. Use the following care instructions for the first wash:
1. Remove liner and dispose. It’s compostable!
2. Throw in the wash with hot water. Use a mesh laundry bag if possible.
3. While wet, remove any additional residue before drying.
We know it’s a few extra steps, but one less piece of plastic in the ocean is totally worth it.

Each pair of Period. swimwear can hold up to 2 tampons worth of blood.
How long will one pair of Period. swimwear last?
You can swim as long as you want. Period blood really doesn’t come out in the water because of the water pressure. But you do flow on the beach, by the pool, the lake etc… That’s what Period Swim absorbs. One pair can hold up two tampons worth of blood.

Personal message from soil: I know it’s highly unusual to get a message from soil but in this case, I just had to say thank you. Just by using one pair of Period underwear, you’re saving the natural world from 9 tampons or 4 pads being thrown away and (because they don’t biodegrade) polluting the Earth for generations. From me and all my microbes - thank you.
