Do they fully replace pads and tampons on heavy flow days?
Yes, on heavy flow days they are designed to replace pads and tampons. If your flow is very heavy, change sooner or consider a higher absorbency style.
What are they made from and how do they feel against skin?
They are made from breathable Tencel Modal that feels soft and smooth, with a built-in absorbent gusset and moisture barrier that lock in leaks and help control odour.

How long will they last and how many pairs do I need?

Seriously the best

I could not ever imagine using anything but these pants for my period, I have various issues including newly discovered pcos, ovarian cysts that need surgery, incredibly painful irregular and heavy periods and these pants SAVE me everytime. I have 7 pairs already and I am buying more right now!!!

So comfortable!

I’ve just had them arrive today. I’m so glad I’ve bought some, they’re so comfortable and of course good for the environment. I work long shifts in a hospital so they will be so ideal, as I’d normally struggle to get change to get to the loo to change a pad. I’ll be recommending them to every woman I know.

Can't fault them

I've tried loads of different brands of period pants and these are my favourite, so comfortable and really secure. Can't recommend enough!

Life changing

I ordered a heavy flow midi brief (3pack) which are absolutely brilliant, completely changed my whole period experience, I no longer dread it and feel comfortable and confident. I would highly recommend these and will definitely be investing in them for my daughter in the future. I have heavy periods and I can safely say I did not leak once! Not even at night which Is always my heaviest time. I also ordered a medium flow hipster brief to try but unfortunately they don’t suit my shape as I have loose skin that over hangs from pregnancy. My only advice if purchasing a three pack, is to wash immediately after changing, a cold rinse then normal wash then hang them straight on a radiator to dry, mine took between 24-48 hours to dry. I will be buying another three pack so I don’t have to stress about drying time. So worth it though!

I tried your pants for this first time last month and I’ve got to say I was very impressed! For a person with a heavy flow who leaked quite frequently in embarrassing situations, I found the heavy flow pants so comfortable and supportive with no leakage!

I have recommended a few of my friends and I know some have now purchased from you.

My life has changed since buying these, they are amazing and comfortable. No leaks even though I have very heavy flow. They really take any worry or discomfort away.

Excellent Period Pants

I wanted to try re-useable period pants in order to reduce the amount of plastic waste I throw away. I bought a pair of the heavy flow pants to try. They are comfortable and very absorbent. I wore them on my heaviest day from 7am until 10pm with no leakage at all. I wore them overnight, again no leakage. I went for a 25 mile bike ride whilst wearing them, no leakage! I was so impressed I went back and bought 3 more pairs of heavy flow & 3 pairs of medium flow. I have had my first 'plastic-free' period & will not be going back to disposable period products. The absorbent padding is (necessarily) thicker than normal pants, this is not noticeable when wearing them, but just means they take a little longer to dry once washed. The pants are so comfy, that I have actually forgotten that I have my period! Great product WUKA!

Great product

I have been using Wuka pants for 2 years and I have been really impressed with the quality and how well they work. I know when I am wearing my wuka pants I feel safe going about my day and sometimes forget I am wearing them they are that comfortable. Thanks I will be buying more.

So so so pleased!

So so so pleased! These came highly recommended by two adult friends. My 12 yr old daughter has recently started her periods and has tried the Heavy pair. They last the whole day (easily long enough for school) and she says they’re really comfortable. She likes them so much more than pads. We bought size small (she wears size 8-10 in clothes). There’s no going back now. We have just ordered some more and she’s already recommended them to her school friend!

Ruby is brilliant at keeping you informed and getting back to you within a day or two about queries.

I have been raving about Wuka to all my friends

I have been raving about Wuka to all my friends. I've been on a more minimalist, eco-friendly journey for a while now and eco-friendly period pads that I'm happy with were one of the last items I've been struggling with. Once I found Wuka I have not looked back. I feel safe going out in them all day and am so much more comfortable at night. The price is still a little much for many of my friends.

Thank you for revolutionising the way I experience my periods.

Just want to say I absolutely love my WUKA Period Pants!!

I spent a lot of time searching for a replacement for sanitary towels that was more environmentally friendly but I always had this weird reservation about reusable underwear. So glad that I took the plunge! They’re so comfy and have massively reduced how much I leak during the night which has always been a problem for me. I do find that the first 2 days when I’m at my heaviest I do have some minor leakage even with the Heavy Flow pair and have to supplement with pads but it’s still a massive reduction in pad usage.

They’re comfy and stylish and I absolutely adore the Wake-up, Kick-Ass message. I love that you’re a UK based company and honestly I just feel a lot more confident and comfortable during my periods now.

Thank you for revolutionising the way I experience my periods.

You folks are amazing.

wish I’d found your products years ago!

I’ve bought several pairs of period pants now from you for myself and my daughter and we both think they’re great! I only wish I’d found your products years ago! I always recommend them 👍

They are amazing

I bought the 3 pair cycle pack for my daughter. She is 12 and autistic, and was struggling with other products. She had tried disposable pads and washable pads, but was not happy with either. We looked at these and she said she would try them because they weren’t too high cut. She has very heavy periods and just uses these day and night. They are amazing. Thank you

ABSOLUTELY love them, it gives me such piece of mind throughout the day and I have done just about everything in them including working out. They are definitely worth the money!

Recommend Highly

I have been using the cycle set for 11 months now. Love them . I use them together with my cups. They work brilliant. I would recommend them to anyone trying cut some bathroom waste. x

They’re amazing

They’re amazing, wish I’d discovered them earlier. But they’re so useful now I am in peri menopause, never knowing when or when I am due a period, which is very heavy now!! Instead of needlessly wearing protection, just in case, and carrying tons of products around, I can wear washable Wuka and feel less wasteful and protected against accidents too 🥰

Bloody fantastic

These are so ridiculously amazing - I have very heavy and painful periods, and being able to shove these on during the day and not worry about changing my pad or leaking has brought me so much comfort, in fact the pants themselves are super f*cking comfortable! You would be a fool for not getting these. They make periods so much easier. I’ve just purchased my second heavy cycle set so that I can just use the pants instead of sanitary towels for each day of the cycle. I’m also currently wearing reusable sanitary pads but find they fill up and leak more.

For full transparency I have leaked a couple times in the pants but that is down to the extreme heaviness of my periods, me wearing the pants for longer than 8 hours and pure laziness hahah.

Otherwise I love them thank you so much WUKA

Great comfort

Was really surpised on how absorbent they are! I wore one on my heaviest day and it lasted nine hours and finding out they can be dried on radiators made it even better!
Cannot believe how much i've saved by using this!
Just wish you could use klarna i'd buy more!

Not only effective, these improved my confidence and anxiety symptoms.

WUKA has changed my life for the better. I used to dread my periods for a multitude of reasons. Nobody talks about this so it seems, but people who have lived with their periods all their lives can still be uncomfortable with some menstrual products--I was scared to even use a tampon or a mooncup for most of my life out of an irrational fear of them. I was stuck with pads--and they were uncomfortable. They tore at my skin, my body hair, they itched, they leaked, they smelled awful, they were laden with weird gel, they shifted, they felt bulky. I came to accept that periods are inherently painful, or that they should be something you're meant to suffer through because how can it ever be comfortable to bleed every month? In a way, I almost internalised some kind of shame for my monthly bleeding. But I was started to unlearn it almost immediately. When I started using WUKA, everything changed. I slept peacefully on white sheets. I was comfortable. I could go for walks, for runs even--without even remembering that I was wearing them. I wore my favourite dresses and everything felt so comfortable and I did not use a single disposable menstrual product all month. They are so comfortable, so easy to clean--nothing of mine stained in the wash. It feels like my period has become luxurious compared with when I did not have my WUKA--I feel safe, comfortable, sustainable, and more in sync with my own body than I ever have before because periods are now just a seamless part of my life.

unbelievably comfy

These pants are superb! Great fitting, unbelievably comfy, no need to keep changing tampons and pads, obviously so much better for our planet, and freeing! I can honestly say this has been the best period I've ever had! I'm never going back. I'm 47 and will be using them until my periods stop and I'll encourage others to give them a go! Thank you.

WUKA period pants are so bloody amazing.

Hi! I just wanted to email my review on WUKA period pants because they are so bloody amazing.

(I suffer quite badly with heavy periods) and my heaviest day just so happened to land on the day I had an all day training day/ conference and my WUKA pants have saved me! - I’ve worn them all day (and I would have probably run out of sanitary products in my bag half way through the day!), absolutely no leakage, no awful smell and I almost forgot I was even on because they have been so comfortable and soft against my skin. I could not recommend them enough to absolutely everyone.

Thank you so much for such a god send of a product!

Revelatory

I've used a moon cup for years but struggled with heavy flow and leaking. These have literally been a revelation - I don't spend my entire time worrying or being very conscious I've got my period. It's been 35 years of that and the second month I used them I suddenly realised I had totally forgotten I was on. I even use them on their own for the last 3 days. No smell, no mess, less cramping, into the washing machine. So good I'm buying my second cycle set.

I'm like an ambassador now :)
