Boyleg Cotton Period Undies

Full coverage. Total comfort. Leakproof confidence.

Fanzy Pantz Leak Proof Underwear is designed to keep tweens and teens dry, odour-free, and comfortable throughout their period—whether they're at school, on the go, or getting a good night’s sleep.

Each pair features a specially engineered multi-layer gusset that holds up to 4 regular tampons' worth of flow. It’s discreet, breathable, and built to move with them—so they feel secure, not bulky.

The Layered Protection System:

– Keeps them dry by quickly pulling liquid away from the surface
– Absorbs moisture fast, holding it safely in place
– Breathable and waterproof to prevent leaks and keep them comfy

The boyleg cut offers full back coverage, making it ideal for overnight wear or anytime they want extra protection and peace of mind.

Made from a soft organic cotton blend, these undies are washable, reusable, and planet-friendly—no pads, no plastic, no panic.

Find Their Perfect Fit

Fanzy Pantz period undies are made for growing bodies — soft, comfy, and secure, with full coverage for day and night. If they’re in between sizes, we recommend sizing up for a little extra comfort.

Need help picking a size?

We’re always happy to help—just reach out!

Fanzy Pantz are made to be reused, loved, and worn again and
again. Caring for them is simple:

Rinse in cold water after wearing, until the water runs clear.

Machine wash on cold in the included laundry bag with similar colours.

Skip the fabric softener or bleach — it can affect absorbency.

Air dry flat (not in the dryer) to keep the layers performing their best.

💡 Tip: Have a second pair ready to rotate while one is washing and drying.

How to Use the Kit

4 Easy Steps

1. Pack it

Pick their size, show them what’s inside, and pop it in their school or sleepover bag.

2. Take it

When their period starts, they can take the bag into the toilet—private, discreet, and ready.

3. Use it

Wipe clean, change the undies, pop the used ones in the laundry bag, and use the heat patch.

4. Restock & Track It

Wash the undies, refill the bag, and use the stickers to track their cycle so they’re always prepared.

    Way better than stuffing pads into a pencil case.

    I was dreading the first period talk, but this kit made it so much easier. We unpacked it together, and it gave us a way to talk about everything without it feeling weird. The reusable undies are soft and easy to wash, and I love that it’s eco-friendly. Definitely one of the best first period kits I’ve seen.

    It didn’t leak at all—even during PE.

    I was super worried about getting my period on a sports day, but these undies are amazing. The leakproof underwear feels like regular undies but more secure. I used the heat patch too when I got cramps, and no one even knew. 10/10 for school days. I'm really glad my mum got this for me. And the bag is so cute. My favourite colour.

    I actually felt kind of proud.

    I got my first period at school, and I had my Fanzy Pantz kit in my bag. I just took it to the bathroom and used the wipes and changed into the undies, and it wasn’t even a big deal. I actually felt kind of proud I was prepared. The stickers are fun too—I used them in my planner. The kit made it way less scary.

    The wipes were a game-changer—for both of us.

    I never really thought about the clean-up side of periods until we got this kit. The wipes are so handy—not just for my daughter, but honestly, I use them too now. They’re gentle, smell-free, and perfect for after sport or busy days. The heat patches? Life-changing. My daughter used to dread her period, but now she just pops one on under her uniform and keeps going. I love how compact everything is, and the little bag fits perfectly in her school backpack. It’s all so well thought out. Total win.
