How to Care for

Your Fanzy Pantz Period Underwear

Rinse After Use

Rinse your Fanzy Pantz period underwear in cold water until clear to remove excess blood and prevent stains.

Machine Wash Gently

Machine wash cold with like colors on a gentle cycle using mild detergent.

Do not use bleach or fabric softener, as this can reduce absorbency.

Air Dry Only

Lay flat or hang to air dry. Avoid tumble drying—heat can damage the absorbent layers and elastic.

Store When Fully Dry

Once fully dry, store your period panties in a clean, dry place or in your Fanzy Pantz pouch.

How do bamboo menstrual period undies help control odour?

Our bamboo menstrual period undies are naturally antimicrobial thanks to a special compound called "bamboo kun" that fights odour-causing bacteria. Plus, bamboo fabric breathes and wicks moisture away from your skin, keeping you fresh and confidently odour-free all day without any sprays or gimmicks.

Is bamboo period underwear safe for sensitive skin?

Yes, bamboo period underwear is safe for sensitive skin. Bamboo is hypoallergenic and ultra-soft, making it gentle on sensitive skin. It helps prevent irritation and keeps things comfy even on your most delicate days.

How much can the bamboo bikini period underwear hold?

Our bamboo period bikini briefs are designed for moderate to heavy flow days. These undies hold the equivalent of 2-3 tampons, giving you reliable all-day and overnight protection without bulk or sweat.

Are these undies leakproof for heavy flow days?

Yes, these period undies are leakproof for heavy flow days. With a 4-layer integrated leakproof barrier, our bamboo bikini keeps leaks locked away so you can move, sleep, and live your day worry-free.

How does the bamboo bikini fit compare to other styles?

The bamboo bikini-style period undies offer a flattering, high-waist fit that gives extra tummy support without sacrificing comfort. It's less coverage than boylegs but more secure than cheeky briefs, perfect if you want sleek style with full confidence and comfort.

Eco-Friendly Comfort at Its Best!

The Bamboo Bikini Period Underwear are incredibly soft and comfortable. I love that they’re made from sustainable materials, aligning with my eco-conscious values. The bikini cut is flattering, and they provide excellent protection. I feel good about wearing them in every way!

Soft & Secure

The bamboo fabric is incredibly soft and breathable, and the bikini cut offers a secure yet lightweight fit. They’re a great balance of comfort and reliability, keeping me confident.

Definitely work! Maybe size up..

So I have purchased a few different pairs of undies and all of them were a medium and I got a medium in this one but it felt a bit tighter and smaller. I still like it and use them it when I am having a heavy day as I know nothing is going to leak out the sides. The lining goes all the way to the top at the back so I feel really secure wearing them. The delivery was super quick tool. I ordered it on Tuesday and got then Wednesday. Next time I might just size up though.

Great absorption

Really like this one, absorbed so well, comfy to wear, great colour! The size I think might run a little smaller than the others.

So Soft and Stylish – My New Favorite!

I am obsessed with these orange bamboo undies! The fabric is so soft and breathable, perfect for keeping me comfortable all day. Plus, the bright orange color adds a fun pop that makes me actually look forward to wearing them, even on my period. They’re stylish, eco-friendly, and provide amazing coverage. Absolutely recommend these for anyone wanting comfort with a splash of color!
