Comfortable but leaked

I found it easy to wear these but they did leak unfortunately. It would make me anxious about relying on them again .
Size wise : a medium was snug but okay on a size 12

Best ever!

As soon as I tired these I was back on the website ordering more. I prefer these so much more than pads and tampons, never had any leaks I’ve had two periods now trying them out. They fit so perfect and you don’t get hot and sweaty in them like you do with a pad, it’s great just not having any rubbish from pads and tampons too. So easy to rinse and then wash. The quality of the product is amazing. I’m actually converted forever! Thank you flux! Also I did try these from seeing Stephanie toms on YouTube talk about them

Great comfortable fit no more blood stained bed sheets.

Definitely love the secure feeling these pants give. They are great for heavy flow over night. I have heavy periods for 4-5 days so would need to get several pairs to wash and dry for each day. They do take a while to dry and can smell musty if stored when not totally dry after washing.
They were dried all day on the washing line on a warm summers day but still damp after 8 hours.
I think they might be tricky to dry in colder months.

Amazingly helpful

I'm a disabled transman who suffers from CFS. I grabbed the boy shorts after hearing about these undies on a youtube video and they have helped me out so much. Not only do they look good, but they are SO comfortable and the style of the undies has a very unisex vibe to them which helped combat my dysphoria <3
These undies really made my monthly so much more bearable, helped me not worry about my cycle and was really easy to use - my CFS thanks you FLUX!

Love the Thong )

I’ve always been a lover of the thong. I’m 60 and ‘occasionally leak. These mean I can wear things again and I’m Single again so want to get out there. Only worn them once, for the whole loonnnng evening and they worked. Waiting to see again next time once they’ve had a wash. Never used reusables, I’m wondering does the small crouch in the pants feel the same once you’ve worn and washed.. they felt really comfortable and no drips or leaks. I’ll update once I’ve worn a second time

Life changing

They fit perfectly, they're comfy and I can wear them all day without having any leak problems. These pair really make you feel safe and I strongly recommend them!
I've even found them easy to wash.

Love them!! so confortable. You can wear whatever you want with them.
I use them with a menstrual cup or for those last days (toward the ends of my period) without anything else.
I bought two of them, maybe I'll need to buy some more!

WOW!

I tried it once, and automatically bought the second ones.
Nowadays I don't know what was I doing before having these sleep shorts.
I prefer them for sleep but I've also used them wearing a dress. So comfortable!
You can be calm while wearing them, carefree.

Another Great Purchase

I love these pants so much I have a collection of styles and absorbency types to see me through each period. I can’t recommend them highly enough. So much more comfortable than pads and tampons.

So Comfortable

I wish these had been in my life for forever! Truely life changing. Much more comfortable than pads and tampons and reducing landfill. Win win! I found them true to size.

Just get them!

Honestly, if you’re on the fence about period knickers, then get off and get to the side where they are worn! I’ve never known a comfort like it. I hated pads, I didn’t want to stick wads of cotton up there and I wasn’t really okay with catching it all in a cup to empty out.

Nay nay. *vomits*

These knickers (pants/underwear/whatever) are an absolute game changer! I put them on and forget about my period (bar the crippling pain that feels like I’m being stabbed relentlessly in the womb by an angry toddler with a fork) and can go about my day literally not worrying. At all.

I have white sheets as well and I don’t have to worry.

To lay it all out there, I’m a heavy bleeder. Shark week is tough one for me and I was forever changing pads cause I’d have one outward flow and that would be it! BUT NO MORE!!

I was a bit “eurgh” about having to rinse the knickers out before I put them in the wash but do you know what? It’s MY blood. It came out of me. If I’d bled on a shirt I’d rinse that out so I try to look at it the same way (and I know it’s different blood - I’m just trying to be positive about it)!

I know this is a long old review but honestly, since I’ve had them, I’ve felt so much better about Satan’s Sacrificial Waterfall than I did before. Just being on my period is *easier*.

Genuinely, if you’ve been considering it, get a pair and watch your life change. I’ve recommended them to every person I know who sheds their uterine lining monthly, and I tell every person I meet about them (I do - I have *no* shame).

If there’s one thing we can do to make the worst part of our collective lives easier, then please, take my long ass advice and buy some. Enjoy the freedom of comfort and safety, even when sleeping!

Thank you FluxUndies. You’ve done me a world of good!!

Big love to my bleeders xx

LOVE THE SLEEP SHORTS

WOW WOW WOW!!!
I absolutely love the sleep shorts! I have a heavy flow and feel particularly uncomfortable at night often waking up a few times worried if I have leaked... but not with these sleep shorts they are the perfect fit and hug your body to ensure no leaks. I am a 10/12 and bought size 12 they are nice and fitted so if you’re inbetween sizes I’d say go for the bigger size. Also very soft & comfy - oh and they are reusable so you’re helping the planet! If you’re thinking of buying then do it! 😊

I can’t recommend these undies enough!! I used them yesterday for the first time and all I can say is WOW!! I’ve just added another two pair (different styles) to my basket before writing this review! Literally changed my period for the better!

Great but size up

They are really good quality nice and thick however I would size up as were digging in a little. They keep super dry for hours they are a little expensive and the pad could be bit longer in all honestly but over all good product.

I'm really impressed with these pants. I've tried several period pants and these are the best. I used it with pads during my period as I have a really heavy flow and without the beginning and ending of period. It didn't smell and although the pads leaked into the pants. It held it there. Really happy with them and will be buying more.

Best night time period purchase

I have a super heavy flow, often having to get up 4 + times in the night to switch heavy duty pad. Slept the whole night through (minus minor unnecessarily panicked checks) without having to get up!

Absolutely leek proof

Wow love these. So comfortable night wear and they give you the confidence to wake up without stained bed sheets.
Why did you not have these while I was growing up??

Okay so I was a little bit dubious about these period pants as I HATE wearing pads, I find them mega uncomfortable and don’t like “feeling” like I’m on my period. Honestly these pants are a bit of a game changer! I’m generally a pretty heavy bleeder so I wasn’t sure whether these would suit me day to day, and particularly at night! But they are so comfy, I feel really secure while wearing them, I don’t have to worry about dashing off to sort my cup out or worry about leaks while I’m at work! I usually wear a cup but towards the end of my period it becomes quite uncomfortable and tedious to change, I have total peace of mind while wearing these and have recommended them to a few people already! You don’t get that wet feeling you do with pants, they don’t bunch or get any thicker no matter how much they absorb! They’re amazing, I’ve bought two pairs and am writing this review to get a discount on my third! Well done Flux Undies, I’m converted!!

Best buy for heavy flow

I already own 3 boyshort and 2 classic bikini but I can't use them on the heavy flow days due to inside-seam and back leakage. This sleep short style is truly a life (and bedsheets) saver.

Sleep shorts

These sleep shorts are the best so far! For the first couple of super heavy days & nights. I use other flux undies for the other days/other flows! For both my teenage daughter during the day & myself. Like that these don’t have flux written on them (which suits my Daughter - doesn’t want to draw attention to herself atall) and that they are shorts!

Great products

I bought the swimming costume and flux undies for my daughter and they're working brilliantly without other products and helping a period not be as big an issue for her
