The pads are amazingly thin and have a great absorbency. I used one for 5 hours and then another for the night with no leaks.
The fit is not great, though. Wings are too loose and the fixing keeps coming undone all the time. For the night, I had to wear it with shorts as I was afraid the pad could move. I believe the wings needs to be shortened and more fixing should be added.

Absolutely love the Flux undies, so comfortable that I forgot I was on my period! No leaks and they wash great too. I'll never go back to pads. These are my first ever period undies and I have to say I'm really impressed.

I love the seamfree design and the rose colour is lovely, the only thing I would change is that the fabric feels extremely thin compared to a similar style from a different brand, almost like it could rip although I'm sure it won't. I also like that they don't have to be washed on a cold wash and can be put in with my regular laundry

The sides dig into my groin, rather uncomfortable to be wear. In all honesty it feels like I’m wearing a big sanitary pad covered in a big pair of uncomfortable pants.

I’ve tried other period panties that just feel like panties. I don’t feel my flow, they feel dry and are super comfy.

These work! Very comfy pants - no leaks, perfect for work and true to size - I will be buying more and weening myself off pads.

I bought 2 size 14/L heavy flow knickers. I fluctuate between size 14 & 16 and these fit both sizes nicely. They were so soft and the lace was stretchy and not scratchy or tight. They don’t roll down, aren’t bulky to wear, look good(!) and provide comfort that they stay in place nicely. Really pleased with these and will buy more even though they seem expensive but they will last. They see me through a night and I have also worn them during the day with total peace of mind. Bring peri menopausal I have no idea what each day will bring so these are ideal.

I have several different period underwear from different companies and these are most definitely the most comfortable and feel the least like diapers! Only thing not as good or better than others is the black lining fabric bleached after just a couple of wears. Other than that super happy with them

Finally I found swimming panties that you can wear safely in water while with your period. I’m so happy about them that I want to buy another pair. Fantastic - it really works!!

I bought the bikini bottoms to support my daughter who was worried she might start her periods on our first summer holiday in 3 years! She didn't and didn't need hers! I did need mine and normally I would just not go in the pool and not bother about it! I have a track record of coming on on holiday! But as it was nearly 40 degrees, even though I was nervous to try them, I was struggling in the heat, so thought I'd give them a go! I was only on a medium to light flow and I did panic a little but after the first time I realised I could trust them and it was a great freedom so thank-you. I wore them under my bikini but they were perfect to wear as they were, they just look like black bikini bottoms.

I was very impressed how thin and soft these were. They had great absorbency but the fit was not great. The wings were too loose and the towel moved around too much and the fixing came undone all the time even ending up in the toilet several time. Good idea but the fit needs some work.

I was impressed with how thin these were considering they are for heavy flow. They are soft and feel comfortable against skin. My only issue is the wings are too long meaning that they gap underneath where they clip together and I can feel them rubbing against my inside leg. Also at times the clip came undone completely.
Overnight they worked well and I had no leakage at all so I will probably stick to mainly wearing these overnight rather then during the day when the wings make them a little less comfortable.

I really wanted these pads to work out for me, the pads are so thin, and the fabric so comfortable that you can barely tell they are there, which is great. The moisture wicking, definitely a plus.

Sadly I didn’t find the pads very secure, the silicone strip on the backing didn’t stop the pad moving around at all. The hook and eye closures don’t feel very tight, they come unhooked easily just walking around the house. Not sure I could trust on a heavy day with that much movement.

Has taken the worry and awkwardness out of periods.

I wear these in bed and omg so comfortable!!!!! I will never wear anything other than period pants again.

These are soooo good. I took a trip to the sea the other day and they held up perfectly, I was a little nervous at first but I had literally no problems!

Amazing product, takes all the hassle out of my period. I used to use disposable pads and switched last year to reusable ones as I thought it would be better for the environment and cost effective. They were great but kept slipping around in my pants, and they were comfortable but not like wearing underwear normally. This is wearing underwear normally. Instead of putting on a regular pair of pants on my period, I just put on these. And there's no mess, no bad smells while you wear them. And when I take them off I just give them a quick rinse before putting in the wash. I can't describe the difference these have made to my life. There's no way I'm going back to even reusable pads - these are lifechanging. Please, if you're reading this, buy a pack of 5 and don't look back.

Others have dug in, these are great and so so much more comfortable than disposable pads!

I bought one pair to try and they made such a difference to my life that I bought two more and will probably buy a couple more! I know, this sounds like an advert, but they really are amazing... totally leak-free, comfortable, attractive, available in lots of sizes including my very big clothes size and you forget you're wearing something functional and can just get on with your day! Awesome!

Honestly I’m just mad I didn’t get these sooner. So comfortable, so secure and so much better for the environment. Thank you Flux

I started using my first pair of flux undies a couple of years ago and I love them so much so I decided it was time to order a few more pairs! I use a cup for the heaviest couple of days of my flow and like to wear flux alongside as backup. I then continue to wear them on their own for the lighter days, they’re also amazing for sleeping and I feel way less worries about leaking than I did with pads! I love that you can choose different styles for different flows and aside from being great period pants, they’re just great pants! Sometimes I wear them when I’m not on my period just because they’re so comfy! Couldn’t recommend more, and I have zero need for “disposable” products any longer!

I slept in these panties on the night of my heaviest flow and they passed the test! I can wear them for 12h without worrying they will leak!

I'm really happy with my purchase. The underwear is comfortable and makes me confident there will be no leaks. It also looks good - just like everyday underwear!

This pair is a must for everyone. Very comfortable, amazing protection. I’m getting 2 more pairs so I can have 3 altogether for my heavy nights. Love not having to worry about leaks. My flow is anywhere from super heavy to heavy.

Amazing product. Especially for the heavy nights.

Love the high waist and sheer panels which make it fun to wear when all my other period pants are rather drab! ... but then the elastic borders are a little tight which combined with my period bloat give me just enough vpl and a mini muffin top to remind me of my self-consciousness 🤷🏻‍♀️ so essentially just like normal really 😂 Won't stop me wearing them though as they are still super comfy and do the trick on light days.
