Proper period pants

Have bought them for my grandaughter..hence 4* she does say they are comfortable and likes the fact that they sit above her bottom and above the front bottom.

5 years going strong

I’ve had mine 5 years now… I’m not gentle with them tbh, they go in the dryer.. they have held up, never any leaks.. but they are getting an odour to them now.. hence being here lol and I’m seeing that you should replace after 2 years 🫣 I’m gonna try the vinegar bath tho, why not 🤷🏽‍♀️

comfy to wear

I usually get the hipster briefs but thought I'd try another style. These Midi briefs are just as comfy and feel nice and soft. I'm peri-menopausal and my cycle changes often so the Wuka briefs are great to wear so I don't get caught out.

Brilliant!

I first discovered Wuka when my sister gave me a spare pair of hers to try. After wearing them out one afternoon and finding there were no leaks or odour, I knew I needed to buy more! I love them! X

Changed my life!

I've only ever used sanitary pads, never got on with tampons, cups etc. But these make the world so much easier - after originally buying four I've already gone back to buy more. I'm size 10-12 and brought medium which fits perfectly. My only thing I would say is that they get really yucky in excerize as they absorb any sweat, but I am hopping to try the leggings or shorts in another paycheck which might solve that problem....

Decided to try period pants after years of using sanitary towels. These are super comfy! Very pleased. I went for a size small as I’m an 8/10.

i like them

first purchase. i am usually a size 10-12 and i purchased a medium. How ever i probably could have done with the size small.
When i first put them on they sound abit rustly, which i dont really like. it made me abit conscious.
Ive only used them twice now, so still in the conversion stage. I need to order more to go fully disposable free but I like not having to use disposable products. I find that they take forever to dry though, which will be a bit of a nuisance but i am sure I will get used to it.

So comfortable!

I have a variety of Wuka pants, all of which I love, but these have to be the best yet! Comfortable without feeling bulky and thanks to the mesh sides, they look good too and don't dig in. I'm always recommending Wuka to friends and will continue to do so.

Fantastic!

I love my wuka pants, so comfy and I feel so secure. I don’t have heavy periods but I went for the medium flow anyway and no leaks whatsoever as I only wear mine for bed. I wish I made the switch years ago! The only criticism I have is that I wish the gusset came up a bit higher at the front but apart from that these pants are fantastic 🤩 I’m wanting to try the stretch seamless and swim wear next! Will definitely be buying some more! Thanks Wuka x

Hello Emma,

We appreciate your kind words and feedback! We're thrilled that you love your WUKA pants, and it's fantastic to hear they provide you with comfort and security.
Your suggestion about the gusset design is noted, and we'll consider it in our future designs. We hope you have an equally great experience with our stretch seamless and swimwear products when you try them. Thank you for choosing WUKA!

Amazing

I have bought these for my 11 year old who is now onto her 2nd show, using pads the first time. The pants are so much more suitable, lasted the day and saved embarrassment in the school toilets when having to open a pad in fear of others listening. My daughter thought they were amazing, comfortable and perfect for her needs. They washed well and are ready to go next time.

Amazing

I had been looking to make the switch to more sustainable sanitary products for a while and I can't believe I waited for so long. These are so unbelievably comfy and now trying to use up the rest of my sanitary products seems like a chore as they're so bulky and uncomfortable whereas these are more comfy than my normal underwear. Looking forward to being able to fully make the switch to only use WUKA products soon. The price is 100% worth it as you know you are buying sustainable fabric which helps the environment as well as reducing plastic waste, please don't hesitate to buy these!

Game Changer

I wish I’d known about WUKA sooner!
Such comfortable period pants with no leaks. I prefer the ultimate range for day time and the basics for night.
I was hesitant to make the switch, but so glad I did!

Excellent

These pants are so comfortable and work amazingly.
Not had any leaks or issues with them at all.
Would highly recommend Wuka to others as a easy alternative to other sanitary products.
Really pleased, thank you :)

I just want to say hi and thank you for your product. I really love it!
I have heard about period pants for a while but I have never dared to try them. It is not easy to change our habits and I was afraid that it would not be comfortable after a few hours. I was positively surprised when I tried it for the first time. It was comfortable, did not leak out, and I almost forgot that it was period pants.
Since then, I keep on talking about your pants to my friends. Thank you!

Would like to thank you for your period pants. I had my first shift at my new job yesterday as a woman with a heavy flow they stopped multiple trips to the bathroom and they're so comfortable thank you so much for your amazing product x

The COMFIEST period knickers EVER!

Honestly the comfiest period knickers ever..

Really comfortable

I bought some of these as a birthday present for a friend and for myself (after we had a chat about whether period pants would be any good!). We're both used to using menstrual cups and/or cloth pads. And we both think the pants are brilliant - absorbent and comfortable to wear all day. Much better than pads sliding around everywhere. I'll be sticking to my cup for heavier days of my cycle, but I'm definitely going to get some more of these (or the lighter flow versions) for spotting days and for wearing at night.

42 years old lady's review

I was hesitant to get period pants as I get extremely heavy periods and I could not see how pants would not leak, I am 42 yrs old and also thought perhaps they were more aimed at teens who get lighter periods. I went for supper with a friend who sung the praises of WUKA Wear so thought I would give it a go and I can not recommend them more, I have not leaked once. I have a heavy flow pair, medium, and light, with how heavy mine is I think I need a second heavy and medium pair to be able to get through my whole period without using anything else or having to wash and dry them to reuse immediately but for a normal period, you would not need all this. They are comfortable, especially for nighttime, and I will definitely be buying them for my girls when they reach that age. I would recommend these regardless of your ethics, even if you do not care about sustainability as they are so much nicer to wear than sanitary towels and Tampax.

Customer Feedback

Ordered my first pair of Wuka period free underwear set last month. Because I was trying such underwear for the first time, I did some basic research to figure out which one should I order and Wuka topped my list! I am a menstrual cup user and on days of medium/heavy flow, it leaks a bit. Before Wuka I used panty liners I was always gutted when using them with a cup. Wuka rescued me! It is comfortable to wear the briefs, I ordered a high waist and brief (both medium flow) to test how it feels. I must say, not once I thought about staining and had a really comfortable, plastic-free, and minus odor period. Especially on the first two days when bloating is at its peak, the high wait brief was quite handy because it gave a great cushion to my belly, I am definitely going to order another of these.

I bought some midi briefs and high waist pants and they’re great. I just bought a couple to give them a try but I’ll definitely be buying more to cover my whole period. Less faff, comfy, I feel good in them and they’re good for the environment!

So impressed

I bought a pair of these to try for my next period. I wasn’t sure what to expect, but they are awesome. They are so comfortable and very absorbent. I have a medium to heavy flow and there were no leaks at all. They washed brilliantly. I only wish I’d discovered these before. I have ordered more pairs as I want to wear them every day I’m on my period.
I’m a 12-14 so went for an L which was a perfect fit for me-comfortable but still fitting well enough not to leak.
