Nice cotton undies

They do what they are meant to. Really thankful for this. They are really great compared to a disposable pad!
But as in every product there is a "but". The side sewing is quite rough which make it hurt a bit. It feels way better than a standard disposable pad but the side sewing is nowhere near ideal. Sorry but my thigh is not of steel ( :) )and I can feel the knots and sewing.
If you ask if I would go back to disposable pads...certainly not! But some work needs to be done to make them more comfortable.

Thank you very much.

Curvy cut underwear

I have a very similar style in another well known brand of period underwear and those have not stood up to these. Flux did everything that pair did not which was retained shape after washing, absorbed well,easy to launder and did not retain any odors. I will be buying more pairs in this style. I have been buying very little disposable s each time I buy a few more pairs, soon I will own enough to rotate quicker to not have to buy them at all. Which should be by next spring.

Nicely fitted without bulk

Having ordered previously I just knew that I would be happy with this purchase. I have tested this pair and say I most pleased with the fabric,ease of washing,cost and the fit. These are highly absorbent with none of the bulk associated with wearing a super thick sanitary pad. I no longer have to worry about a leak in bed or ruining any new bedding.

So far, so good

Does what it says on the tin. Have used these for 2 periods now, I either use them with my menstrual cup on heavier days just in case, or on the last day of my period.
They're quite thin, which is great, and the design isn't bad either.

Love it

Super comfy, super secure and a super dry and clean feeling. Will never use anything else.

No Leaks

I already had some of the heavy flow pants for the first few days of my period and brought the medium for the last few days. They are comfy and I feel assured I won't leak and they're easy to clean.

I didn't love the shape/look of the pants when they arrived, but once I tried them on they felt very comfortable. Compared to other menstrual undies I own, these are more comfortable and I have the feeling the material is lighter and breathable. They don't feel as hot as others. Easily washable, no stains and no bad odor.
During the day I do not dare to wear menstrual pants alone, I always use them together with a menstrual cup. I use nothing but the Flux pants at night or on the last few days when the flow is lighter. So far I haven't had any leakage problems.
One important thing if you are buying from outside the UK: I had to pay customs taxes to pick them up at the post office. After paying that, the total cost is not so attractive compared to other brands.

Comfortable eco choice

Good quality eco alternative to single use sanitary products. They’re comfortable and easy to wash, although they do take quite a while to dry so I’d recommend buying enough pairs to last your whole period if you can afford it… they’re are quite pricey, but I’m seeing them as an investment that allows me to take positive action.

Size-wise, I’m a pear shaped size 12 but bought size large (14) for a comfortable fit. Glad I did, I think size M (12) would be too small.

Awesome

I used to wear two extra large pads at night, sometimes having to get up in the middle of the night to make sure there was no leak. I used to spend super uncomfortable periods, trying to stay perfectly still for the entire night otherwise I'd have to change my sheets every morning. I've been using the sleep shorts for two months now and it honestly changed my life during my periods. I can sleep through the night and I am not worried about leakage anymore. It's comfy and perfect!

Very comfy

Really comfy and soft and just like a normal pant. The only small thing for me is that the pad could do with being a little longer as I have found sometimes at the front it doesn’t cover as high as I would like.

Fantastic pants!

I literally can’t stop raving about them. They have made having your period so much more comfortable (& are especially good after you have had a baby & are looking for other period product options)

Pretty good

Quite good but I have quite a heavy flow and the pants didn’t leak as such but you could tell that the blood was starting to come through the bottom, although this was probably my fault as I’d been wearing them longer the recommended time. Also, the pants have been stained an orange-red colour. Aside from these minor issues the pants were good, comfortable and I didn’t have to worry about leaking all day, also there was no smell, so I will continue to use them.

No more waking up in a pool of my own blood. It's less goth but also less laundry.

Great buy

These were my first attempt at period pants and I was super happy with them. Used them on my heaviest flow day, without any additional help (tampon) and I was fine throughout the day, probably 6-7h straight. Now looking to find the equivalent for nightime as was let down by my other pair of Heavy Flow Flux undies....

I have just ordered a second pair my

I tried another brand when I ordered these. Ordered 5 to get the maximum discount too. They were awful in comparison to these. These pants were ready to use and stayed leak proof all day. Would highly recommend.

Life-changing

I don't know why I waited this long to get this. I use this every night I have a my period and have just bought two more. It's super comfy.

I'm also normally a size 12 and so bought that size. Perfect fit. Absolutely highly recommend this product!

Peace of mind on long haul flight

I recently wore this on a long haul flight. I was worried because the flight was meant to be on the heaviest day of my period, so after reading rave reviews about the FLUX Sleep Short, I decided to give it a go (leap of faith after a bad experience with a different brand of period pants). I changed into them about 3 hours into the 13 hour flight and it kept me leak-free, dry and comfy for the remaining 10 hours. I changed out of them once I landed as it was starting to feel a bit "full" by then and put them in a ziplock bag. Really glad I bought these and will be wearing them to sleep in the future and will be buying the others to use during the day!

perfect for sleeping & sport

the fit is good, snug & comfortable, shape is simple and looks as promised.
with very Hight absorption it is great to sleep or for those with high flow.
i love that the absorption pad goes up the whole back: again perfect for sleeping, sitting/laying in weird position or for sports without worry!
would love more colours for this
