WHY YOU’LL LOVE IT

WUKA Ultimate™ Midi Brief Super Heavy Flow Period Pants are our most absorbent underwear ever. Designed to replace tampons and pads completely, they give you peace of mind on your heaviest days or nights. With a high gusset for full coverage and leak-proof layers, they’re built for confidence when you need it most.

HOW IT WORKS

Super Heavy absorbency holds up to 60ml — the equivalent of 12 tampons or 8 pads. The absorbent pad is around 3mm thick (similar to a super absorbent disposable pad) yet feels soft and breathable thanks to TENCEL™ Modal fabric. Wear for up to 12 hours depending on your flow.

BEST FOR

Very heavy periods, postpartum bleeding, or moderate bladder leaks. Perfect for overnight protection, long shifts, or days when you need maximum coverage and security.

  • Made with sustainable TENCEL™ Modal — 3.5x softer than cotton
  • Reusable — each pair saves 200+ disposables from landfill

Excellent for front sleepers

I would highly recommend this product! I ordered a size larger than recommended ( so I got size large) because I don't like tight elastic and they actually fit perfectly on the waist. Not too loose not too tight! They are a little loose on the leg hole and I leaked once because of it but if it keeps happening I will just sew a tiny tuck in the side of the leg. I probably have different waist to leg proportions compared to others.

Super comfortable and very absorbent and perfect for front and back sleepers!

Comfort and strong absortion power

incredible: super comfortable and they have strong absortion power (my period is very strong). I have tried them this period and I am totally delighted. Will probably order a couple more of them. The package option are so worth it. Way much better than tampons and other stuff, because is healthier for us and is also very easy to clean.

Reliable and comfortable

Just refreshing my stash of Wukas some of which are over five years old. These weren't available when I first started to use Wukas but they are my favourite. High coverage to the front and back so I can sleep with confidence there will be no leaks. So soft and comfortable to wear.

Wore all day and no leakage

Wore my first ever time in a day out for around 7+ hours on the first day of my cycle (heaviest day) and it was brilliant. Didn’t feel uncomfortable or need to keep going to change pads. Soaked everything up and then I washed it and put it in the washing machine. Hoping there’s a sale so I can get more.

Change of life

Best product ever, I first started to use these underwear and my life changed . Before I always had leaks because I have a very heavy period but now I have no more worries of being embarrassed in public. Also I plan to buy for my daughter at the time she will need. These period pants changed my life I just love them and I recommend them to all my friends xx

Feels like underwear! No smells, it works!

I’m surprised how dry I feel while using Wuka. I was afraid of the smell or sensation, but it actually works! Feels like a normal pantie, I bought M because I’m bloated those days and wanted something not too tight to my body, they look bigger when they arrived but no issues whatsoever.

Passed the horse riding test!!

I can not rate these highly enough. I had an equestrian event where I was riding for 5 hours in beige breeches, I really did not want to miss it, but also knew I was due on the same day and it was going to be heavy flow day! Totally night mare! I was so anxious, found these online, did a last minute purchase. WOW!!!! They totally worked, no bleed though at all! I will be purchasing more and never missing a riding event again! Thank you Wuka

A total game-changer!

I wish I’d known about them sooner. I couldn’t believe they would work but they do, and so well! I’m comfortable sleeping with them knowing there will be no leaks, unlike pads. No pad was good enough to contain all this heavy flow - but the Wukas are just amazing. Have been recommending them to friends.

Utimate Midi Brief Super Heavy

Bought these for my daughter - she has never had the Ultimate pants before, but has been using the basics for 2 years and the teens. The fit is comfortable, however, the padding stops short at the back of the pants unlike the basics and does not go all the way up, so not the best for night time use. She was pleased with the comfort and the absorbency, but after just one wash, the elastic around the waistband on all 3 pairs has already frayed.

Ultimate Comfort for Heavy Days

I had to size down from my usual size, and they fit perfectly. The WUKA Ultimate Pants Super Heavy are super comfy, absorbent, and keep me secure all day. Highly recommend !

Comfortable, Absorbent, and Perfect for Heavy Days

I’m not sure if it’s just me, but I had to size down from what I usually order. These WUKA Ultimate Pants Super Heavy are amazing! So comfortable, super absorbent, and perfect for those heavy days. I’m definitely a fan

Comfortable, absorbent and reliable

I feel so secure wearing these on my heaviest day, the material is so soft and comfortable, I don’t feel any irritation or discomfort. And I super from very heavy periods so to have a pair of reliable period pants is a dream. I think everyone should invest!

I love these. Comfortable. No leaks. I feel confident on wearing them even on my first day.

Brilliant product!

My daughter has used these since she started her period and they’ve been very reliable. Leak free day and night. Wuka has made, what could have been a stressful time in my daughter’s life, a lot easier.

Bought these for my 14 year old daughter

My 14 year old daughter said these were very comfortable and I have ordered her some more. Have previously bought her similar products from another company, which had to be washed on a gentle setting in the washing machine. This didn't get them properly clean and so I used to put them on a 30 degree wash, which has seen the fabric disintegrate over a few months. WUKA products are recommended to be washed at 30 degrees, so I'm hoping the same thing won't happen!

Sanity saving

As someone who suffers horrendously heavy periods the super heavy has allowed me to be able to do so much more, when I was on disposables I was having to change night time pads every 1-2 hours now I get at least 4 hours

The ‘label’ disappears after the first wash

Love all my WUKA pants, I’ve recently taken the plunge and switched from another brand and am so impressed with them.
The only problem is the text in the pants (stamped in instead of a label) has washed away after just one wash in most of my pairs! Now I can’t easily work out which flow day each pant is for, which is a little frustrating. I’m sure I’ll work out with time, but had hoped this would be clearly visible on the pants for at least a few cycles whilst I got to grips with them.

Excellent.

These are my favourite period products. I can get a good night's rest with no leaks. For really heavy nights I double up for piece of mind. So comfy. They do take a while to dry so stocked up during earth hour.

Game changer

I've used Wuka for a number of years now, and these are definitely my favourite. They are so comfortable and very easy to wash. If you're on the fence about reusable products, I would encourage you to give them a go!

Excellent

Some of my pairs are now nearly 4 years old so I've been updating my stash as oldest ones needed to go. Since I first found Wuka they introduced the super heavy which are best for me on really heavy days I don't have to double up heavy flow pants in the day. I find them very comfortable and prefer them to pads
I do wish the super heavy were available in a version without the mesh for my preteen though as it's not quite appropriate with the mesh for her age what with PE days playground visits and her really still being a girl. The teen range don't fit her so we had to go for the basics in the women's range. She also finds Wuka more comfortable than pads. They allow her to just get on with her day-no worries

Hello Carole,
Thank you for your feedback. We're delighted to hear that our super heavy pants have become a reliable choice for your heavy flow days, providing you with comfort and security. Your feedback about a version without the mesh for preteens is noted and appreciated. We're glad that both you and your preteen have found Wuka to be more comfortable than traditional pads, allowing for a worry-free day.
If you have any more suggestions or questions, feel free to reach out. We're here to help.

Great product

Ordered this for my daughter and they are comfortable, NOT leaking and looking pretty on her with the mesh side panels.

Great for heavy days

I get WUKA for my teenage daughter as she loves the freedom and comfort the pants give her. She wears the adult sizes as she is tall and the teenage ones wouldn't fit. She has them in a range of flow from medium to super heavy and the super heavy give her added confidence on the first day and night during the worst flow. As a parent, I'm not sure that I like the mesh on them for a young person and some colour options would be nice. But she loves them and that's what counts.

Better than any pad/tampon combo

As super heavy bleeders these are great for during the day on the heaviest days, or overnight on the lighter days. Super comfortable.

Brilliant

I recently bought these during the sale as they were too good to miss. It's my 3rd pair from here now (all different styles and flows) and they fit well and go a great job. I have particularly heavy days at the start of my cycle so I needed some really heavy flow pants to help and these fit the bill perfectly. I would buy these again.

No 1 Fan xxx

I converted to WUKA about 8 months ago, brought these to top up my stash. I now have 6 pairs in total which get me through each period. I recommend these to everyone I meet, and I have already brought my daughter the teen starter pack ready for when she eventually starts.

Piece of mind all day long

I bought these briefs so I could wear them for a full working day without needing to change underwear midway through during heavy parts of cycle. They are great!

The fit is comfortable and secure. I feel confident that I won't have leaks when wearing these.

The fit to size is good.
