Leak-Free Swimming: Our 8 Favorite Period-Proof Swimsuits

Leakproof Classic One-Piece

Check Latest Price

KT by Knix has a whole line of period-proof swimwear (scroll on down to see their other options). They're totally wearable without pads or tampons, but if you're worried and it's a heavy flow day, they suggest wearing them in combo with pads or tampons for two levels of protection. The swimsuits trap and absorb the menstrual blood, so even when you get in the water, you'll be worry and leak-free. There's an ultra-discreet absorbent pad in the gusset liner that absorbs up to three teaspoons of blood (which equals about three tampons).

This KT by Knix Leakproof Classic One-Piece swimsuit is super cute and super practical. We love the adjustable straps and non-dig leg opening. It also comes in extended sizes that support bigger cups (yay for big-boobed ladies!). Wearing this swimsuit, you'll look and feel good!

Next up, we've got Modibodi period-proof swimwear. Modibodi is an amazing company with a whole range of period-proof clothing. They've got activewear, underwear, overnight clothing, and more. And we absolutely love their menstruation-friendly swimsuits.

Their Swimwear Recycled Hi-Waist Bikini Brief looks great, is good for the planet, and is so helpful during that time of the month. It absorbs up to 10 millileters of blood (equal to two teaspoons or two tampons). It's perfect for spotting, discharge, or light to moderate flow days. It's available in black.

Flattering and functional? Heck yes.

Ruby Love is another company that we love that offers period-proof swimwear. Just like with other brands, these swimsuits can be worn with or without pads, tampons, or menstrual cups.

This cute, polka-dotted double tie bikini bottom has a built-in absorbent liner. It has up to three tampons worth of protection (or, if you pair it with their Double-Sided Pad, it has up to six tampons worth of protection!). Their dri-tech mesh prevents all front, side, and back leaks. And it's plastic-free, sustainably-made, and odor-free! What's not to like??

We just love this Ruby Love off-the-shoulder period swimsuit.

No tampon or pad needed with this absorbent and leak-proof swimwear. The off-the-shoulder neckline is especially cheeky, flirty, and cute. We're going particularly gaga over the Burnt Sun color, but Ruby Love also has it in Black Sea (black), Hawaiian Mountain (rich brown), Floral Vacation (green, purple, and pink floral pattern), and Set Sail (adorable black-and-white stripes).

One satisfied customer found this bikini brief to be just the thing she needed: "I am really happy with these, I'm not sure how they work but they do! So glad I can finally swim whenever I want.
