Rinse After Use

I absolutely love the buttery feel of these period undies, they feel better than other brands I’ve tried so far. They also give extra padding along the seam which offers more protection so you don’t have to worry about any embarrassing moments or leakage!
I also love how they double as boyleg shorts so you can use them for the gym or going on walks & hikes.
I wear a size medium & generally a size 10-12
Wore these on a hike, and they held up incredibly well! No chafing, no leaks, and I stayed comfortable the entire time. I didn’t think period underwear could be this good for outdoor adventures!
My daughter has the Fanzy Pantz kit in her locker at school with the wipes and period knickers, ready for the day she get her period, in case it’s at school. This gives her confidence and comfort if it should unfold that way. The undies feel very nice and soft - will stock up on her correct sizewhen she reaches that stage in her life. The kits are so perfect for Mums looking out for their daughters, so when the time comes she feels in control, not embarrassed or overwhelmed. So good.
Absolutely LOVE these boyleg period undies. I started using period underwear as overnight pads were just not enough, they would always leak. But was also struggling to find comfy underwear that don’t leak. These solve both problems, they don’t leak and are super comfy plus don’t have any nasty chemicals. Will be trying out more of the range!
my daughter was so happy when she recieved her order in the mail.. She has already used one of the heat packs... we couldnt believe how long the heat lasts for will definitely be ordering more..
If anyone is looking at this product and isint sure all i can say is give this product a go you will not be disappointed.
So comfy and so much protection!! Absolutely love these 😍

I find these undies so comfortable. Way better than wearing a horrible big pad on those heavy days. And the best thing is that you can use them without anything over the top. No one would even know they are underwear.
These are for when you want to feel just a little extra, even on your period. The lace detail is so cute, but don’t be fooled—they still bring their A-game when it comes to protection. Perfect for a weekend getaway or a spontaneous night out. Who says you can’t have it all?
These are the kind of undies that work as hard as you play. Super comfy for lazy mornings after a big night out but strong enough to keep you confident at a music festival. I’ve danced, traveled, and lived in these—they never let me down. A true wardrobe MVP!
I adore the Lace Cotton Period Underwear! The lace detailing adds a touch of femininity, and the cotton fabric is soft and breathable. They offer great protection without sacrificing style. I feel confident and chic, even on my period. Thank you, Fanzy Pantz, for making period wear beautiful!
I absolutely love these Boyleg Cotton Period Underwear! The soft, breathable fabric keeps me comfortable all day, and the boyleg cut provides full coverage without feeling bulky. No leaks, no worries—just pure confidence during my period. A must-have for anyone seeking comfort and peace of mind!

These Boyleg Period undies are a great blend of comfort and functionality. The boyleg style doubles as workout shorts, making them ideal for active days, while the breathable cotton and reliable absorbency keep me feeling fresh and secure. These are a game-changer for busy, active lifestyles!
I probably shouldn't say this but I've always been a Modibodi girl until my best friend told me about these undies. I was really suprised by how quickly they absorbed and I stayed fresher and cleaner for way longer. I didn't think that peiod underwear would be so diferent but they are. Ladies, if you love period undies, I suggest you try these. They are comfy, look great and work so bloody well.
I've always been a really heavy bleeder over night. It's been a nightmare forever but my friend recently told me about these undies and since I got them, I haven't had to put a towel down on the bed or get up loads of times during the night to change the pad. So I can honestly say, now that I'm using these pants I sleep better and I am not having to wash the sheets as much. And, they are super easy to clean. I just rinse them in the shower during my morning shower and dry them. Then I throw them into the wash bag and machine. Love them.
The lace on these make you feel so much more better about yourself when on your period. I love the fact that you can still wear nice underwear with some style while on your period rather than a basic black pair and an uncomfortable pad that moves all the time. As someone who is very heavy with their period, these are perfect and also super comfortable
Personally, I love boxer pants and to have them as a pad built in is a life saver. They are so so comfy and I honestly wear them like bike pants around the house sometimes and not having to worry about bleeding through is just another stress free thing to have to worry about. Love Love Love
These are truly amazing! The Boyleg pants are incredibly breathable. I don't typically wear boyleg style, but these are so comfortable, especially for my heavy nighttime flow. No leaks or worries, just total peace of mind.

The lace cotton period pants are incredibly breathable, which makes them perfect for all-day wear. I can confidently wear them under a dress and still feel sexy and stylish. They offer complete protection with no leaks, and I appreciate how breathable they are, especially since it's important for my skin. The soft cotton fabric is also a major plus—it's gentle on my skin and never itchy, making them a comfortable choice for long hours
