FAQ: WUKA First Period Pack - Stretch

Confidence-boosting first-period set with Teen Stretch™ Heavy pants, a two-pocket wet bag and a positive body book; teen-fit, breathable and made for real life.

How does the Teen Stretch™ fit work for growing bodies?
The Teen Stretch™ design fits across three sizes with a teen-specific mid gusset. The fabric stretches bi-directionally to adapt to changing shape for a secure, comfy fit.
How absorbent are the pants and are they OK for school, sport or overnight?
Heavy Flow absorbs 20ml+ (about 4 tampons or 3 pads) and offers up to 12 hours of protection. Great for lessons, sports and sleep—change sooner if they start to feel wet, as everyone’s flow is different.
What Gusset Style are Teen Stretch™?
All Teen Stretch™ period underwear come with a mid-height gusset
What does the two-pocket wet bag do and how do we use it?
Use one pocket for a clean spare and the other for used pants after a quick rinse. It keeps school bags organised and makes changes easy at clubs, sleepovers or on the go.
How do we wash and care for everything?
Wash before first wear. After use, rinse in cold water until it runs clear, then machine wash at 40°C without fabric conditioner. Air dry inside out; do not tumble dry or soak for long periods.
How long will the pants last and how many pairs are recommended?
Reusable for up to 2 years with the right care. Many families find 5–7 pairs cover a full cycle; the kit is a solid start and you can add more pairs as needed.

Fantastic products that fit well

Fantastic products that fit well. 💝 the option to have a full refund if the fit isn’t right is really helpful. Other companies don’t offer the same deal. I have always experienced good customer service and I can’t say that for other period products I’ve bought online. Really happy overall with Wuka’s products and customer service x

My teenage daughter was wearing the Wuka pants

My teenage daughter wears her Wuka pants with such comfort and confidence. She wears them during martial arts training (wearing her white uniform), and althrough schooldays. They perform brilliantly. She immediately asked me to order more! I am very happy seeing her so at ease and comfortable during her periods. A top tier product!

Not to be dramatic…

Not to be dramatic. But these have changed my life!
As an endo sufferer periods are **** on earth. I’m unable to use tampons because of swelling and pads are well… pads- pretty icky feeling.
I was worried about the absorption- would it be just like a pad? I am very heavy every month so was also worried about leaks.
I’ve worn my pants for the first time today- absolute game changer. They are comfortable, have the perfect amount of stretch and they actually work!!
Just wish I would have tried these years ago!
If you’re on the fence and reading reviews, thinking about purchasing- do it! You won’t regret it and it will change your life!

I can trust them

I had a hard time trusting for the first few wears, but now I can confidently sleep through the night or go about my day. The teen size S-L worked great on my 5'3" 115 frame and I am an adult. The one star off is because I'm still haven't figured out an easy way to wash them easily and thoroughly.

Lovely Peace of Mind.

It’s so lovely as usual to get some more of the Wuka products. This is for my daughter in expectation of her first period. My older daughter uses it and we are so glued to Wuka! Thanks for the peace of mind and confidence that Wuka offers. My daughter isn’t scared of that aspect of growing up❣️

So good! 💓

This is the best period underwear mr daughter has tried! My daughter is 13 and hates having to change her pads at school and she often worries a lot about leakage. We tried the modibodi ones in moderate flow but they didn’t last long and she didn’t like that you could see the actual gusset through them. These are amazing super smooth looking like normal underwear they last her a full school day and she doesn’t have to worry any more thank you 💕

Excellent product these are to replace ModiBodi

Excellent product these are to replace ModiBodi ones that just always leak. The Wuka are by far the superior product with no leakage issues. The feel lovely and have a better gusset protection.

Even better than expected

Delighted with these pants. First time trying period pants and they have been everything I hoped for and more! They’re really comfy and have been great for all day wear without worrying about leakage/smell etc.

I know these pants are advertised for heavy flow and for teenagers, but I thought I’d give them a try as I have fluctuating flow and am a petite female. I figured they’d work well for adults and looked comfy. I thought they would be bulky as they are sold as heavy flow but they’ve not been that at all. The looked really small when I took them out the packaging but they’ve stretched perfectly to fit me. Kind of sad to go back to my regular pants as these stretch well and the fabric feels so nice!

Great

Was a bit skeptical at first if it would work but bought for my teenage daughter and she loves them. Comfortable, no foul odour and keeps everything in. Will be buying some more.
