How much period blood do Super Heavy Pants Hold?
NEW Stretch™ Period Pants For Super Heavy Flow absorb 60ml of blood - the equivalent of 12 regular tampons and 8 pads.
Will switching to WUKA save me money?
Yes! Switching to WUKA is definitely a cheaper alternative to monthly usage of pads and tampons. WUKA period pants were the first in the world to completely replace pads and tampons- meaning even on your heaviest flow day you can be worry-free with zero leaks and odours thanks to our fast absorbing, quick drying underwear.
Are these suitable for wearing at school?
Absolutely, these were made for wearing on long days at school, trips and even sleepovers. Due to the double absorbant inner gusset, these pants absorb so much more period blood meaning you can wear them for up to 24hrs. Change them as soon as you start to feel wet- remember everyone's flow is different!
What is Stretch Technology?
In true taboo-breaking WUKA style, Stretch™ features our new patented Stretch™ technology— a meticulously designed suspended gusset is built in to each pair of underwear, engineered to retain its stretch, expand or contract depending on your unique shape. Figure flattering with a completely seamless construction, you’ll find no VPL’s here.
What is CoolMax Technology?
CoolMax™ Absorbent Technology fabric is used features in the top two layers gusset offering faster absorption for less chance of leaks and odours as well as faster-drying time post washing.
Are these period pants suitable for people with fibroids, PCOS, endometriosis or adenomyosis?
Yes, in fact these underwear were designed with you in mind. We understand how debilitating these conditions are and how super heavy flow requires additional protection. These pants will hopfully provide you with additional comfort and confidence on the heaviest days.
How do I care for my WUKA period pants?
Please wash these pants before wearing for the first time. Our WUKA Stretch period pants require a cold wash only. If your machine doesn’t have this setting, hand washing is your best alternative. We recommend treating your period pants as delicates. Using our mesh laundry bag will help to protect the fabric and prolong the life of your underwear.
How do WUKA period pants work?
Layers. Our many layers contribute to making sure you get a long lasting feeling of dryness and security, not having to worry about leakage, smell or infection. Every pair includes a super absorbent gusset which consists of many layers, the middle layers absorb and lock in the blood whilst working with the outer layer to ensure you stay dry through your day to day activities! Period pants look and feel like your regular underwear but they are leak-proof, which means you don't have to wear a pad, a tampon or menstrual cup when you wear them during your period.
How many pairs do I need?
We find that 5-7 pairs is best for most customers considering they last up to 2 years. Check out our savings on bundle cycle sets for 3 to 5 pairs.
I have really heavy periods, will I need to use any additional products?
It depends on the level of absorbency that you need. WUKA are designed to hold a certain amount of menstrual flow, as specified on our website from light flow to super heavy flow. If you have a very heavy flow, it's always best to carry extra pants.
How long will my period pants last for?
WUKA period pants can be reused for up to 2 years. For the first 40 days after you receive an order we offer a 100% satisfaction guarantee on your first pair of WUKA pants.
Do WUKA pants contain PFA's?
The simple answer is no! WUKA has been committed since day one to not use any harmful chemicals in the production of our products. All of the materials that we use are planet friendly, animal friendly and contain no added chemicals, such as silver or antibacterial treatments, stain-resistant or Perfluoroalkyl and Polyfluoroalkyl substances (PFAs or PFSAs). All WUKA are independently tested by Highstreet Textile Testing Services Ltd (HTTS) who guarantee there is zero trace of PFA's in our products.
How do I wash and dry my period pants?
After use, rinse with cold water until the water runs clear. This is best done immediately after removing. Pop your WUKA with similar, dark coloured garments and wash at 30-40ºc, inside out. Don't use fabric conditioners. Air dry your WUKA Period Pants outside on the line or indoors on an airer. Don't tumble dry it. For the Heavy Flow and the Super Heavy Flow, we advise washing inside out and giving them an extra spin. As well as this, we recommend sticking on a warm radiator to ensure complete dryness. We always advise washing pants as cold as possible. This will prolong the lifespan of your pants and also keep the absorbency as high as possible. Refrain from drying in a dryer or on a radiator (if possible) and always dry inside out. We would not suggest leaving your WUKA pants to soak for a prolonged time, this can cause the material and bonding to wear and damage quicker.

Mum of 3 teenage girls

I don't usually write reviews but I had to come here and share my thoughts. I have a 3 teenage girls and these period pants are nothing short of AMAZING! Never once have they leaked (one of my daughters has a very heavy flow) and they are perfect for in the day and nighttime. They are soft, stetchy and all 3 of my girls love these. Highly recommended. No more scrunched up pads. Game changer!

I love the ethics of your company

I love the ethics of your company, its journey from the past, the now and future aspirations. I feel like I’m buying into decency and hope, if that makes sense.
You have all given my autistic daughter a sense of calm, peace and at ease with how soft and comfortable your pants are. She wears the light ones everyday! It helps her confidence, thus aiding her concentration, so she can learn at school and self regulate knowing she is safe wearing them, should her period start or when it does.
I am very grateful to you.

These were really great for my teenage daughter

These were really great for my teenage daughter.
They worked great for sport and fitted well.
She’s a very slim 14 year old and I was unsure about the size range but they’re a good fit.
Would definitely recommend
