Absolutely love, Amazing quality!!
They fit really well and the g-string ones are great for the start or end of your period. Would recommend 👌
I love them they’re amazing! And so comfortable
I have tried other period Gee’s that do not give me the confidence these do! They are also great for the gym as they are seamless so you can continue wearing tights and nothing shows.
Arrived so fast. Awesome quality
absolutely love this brand!
I love them so much! They are so comfy and they don’t look tacky and still make me feel confident even when it’s that time of the month. They are for lighter days and I’m definitely wanting to buy the heavier period undies 💚💚💚 thank you!!
These are a life saver!! As someone who has always struggled with reactions from pads, and inconsistent flow for tampons, these are a game changer!! I wear them everyday. Even when I am not on my period. As I work a very manual job. I get sweaty down there. These genuinely help with that too! I love them so much, I am now ordering different styles. Super comfortable, extremely absorbent, easy clean. They take about 1.5-2 days to fully air dry. But even still. I could not live without these!!
The fit is perfect and the material is so buttery soft making my period more comfortable and stylish!
Absolutely love these! They are cute, reliable, comfortable and ethical! Definitely telling everyone about them 💚💚💚
I love the underwear! It totally works and it’s also very comfortable
I'm not normally a G girl, but I thought I would give it a go. So soft so comfy.
Durable
Wow. As a girl with a very heavy endometriosis flow, I am constantly bleeding through tampons, pads, thongs, etc. This has genuinely changed my life. I can wear a smaller tampon which doesn’t hurt as much AND still be protected from my flow AND workout in my sexy leggings with these thong panties. Iconic!!
Absolutely the best undies I’ve owned. Thank you for making it easier to go gym with bulky pads nowhere to be see.n
They are so comfortable and work perfectly. Even while working out they've been great. So happy I found the website!
Great product! Fabric is good, durable and loving the fit. Great for exercising
Best period underwear on market. Ive tried so many and these are the first comfortable stress free period ive ever had and im 32.
Amazing quality and they look so good! So happy with them
Great, soft fabric, comfy.
so comfy and great design and shape ! wish they came in a xxs as the xs is slightly loose around the crotch for a size 6
So comfy! Does the job
Fits to size
Awesome! Perfect for backup while using my disk or on the last day or two of my period
Love these
Great product
Great product
So comfortable and flattering to wear on light flow days under activewear. Have purchased more. Love them!
These are Epic. Great everyday. Highly recommend.
Love these! Need to buy more but lost weight to unsure on sizing.
Love this underwear. So comfortable and I haven’t bought panty liners in years. They G-string underwear doesn’t even feel like they’re period underwear. Love them they’re great.
Makes the those lighter days feels so much more secure!
Honestly if you’re thinking about trying these just do it. I bought the 3 pack- got 2 free, in red. My partner calls them my shark week undies. They’re comfortable absorbent and you’re unable to tell that you’re wearing them. My period varies as u have an IUD, sometimes it can be what is considered light and sometimes it’s heavier. Sometimes I have a few days of it being “heavy for me” with spotting either side. It’s the spotting that ruins my other underwear. Knowing I have these now is life changing. I don’t get caught out as much and I’ve saving money in not having to buy sanitary products. For those worried about the “look”- There’s a slight bump on the front where the thickness changes for the absorbent layer, it’s something you can feel rather than see. Knowing I have that layer is comforting as having a liner/ pad on. It moves with your body, doesn’t stick in weird places and you don’t have to deal with the sound of opening products in the bathroom. Which is silly but was something I was always conscious of. There’s a little more you have to do instead of just throwing them in the wash especially if you’ve got a heavier flow.. that’s the only “con” if you could call it one- It’s basic hygiene. Thanks Aunt Flo for putting these out on the market. It’s made the logistics of managing my periods a little easier x
These are a PERFECT addition to my period undies wardrobe!!! Love them for those tights/gym moments. Full gusset means no leaking from the front or back!
So comfortable!
Honestly SUCH a game changer. I already had full briefs, but ordered the g-strings for under my gym gear and i LOVE them. So comfy. So soft. I even wear them on non-period days!!
These are a game changer! Beautiful fabric, feels like normal underwear but you're protected. Wish I got some sooner.
effective and comfortable. true to size!
Absolutely fabulous comfy and discreet
Love mine
