How to Measure Your Hip SizeHow to measure your body

WUKA TIP: No tape measure? 
You can measure yourself with a belt or dressing gown cord and a 30cm ruler! Tie the belt around your hips, place a piece of tape or pinch where it reaches, then lay flat and carefully use the ruler to measure the length.

WUKA Ultimate™️ Bikini Medium Flow period pants are your complete tampon and pad replacement. Wear them for up to 8 hours on all but your heaviest days. You know your flow best. 

Holds at least 15 ml of period flow or light leaks / 2-3 tampons' worth.

    Happy Customer

    I just wanted to let you know I am delighted with the WUKA briefs I recently ordered, hence I’ve ordered more!
    A friend recommended them to me a little while back and I have to say I wish I had ordered them much sooner, as they are an absolutely amazing product.
    I am so impressed by the fit, the feel of the fabric and how well they absorb my period and that I feel fresh and clean throughout the day.
    I have felt confident wearing them throughout my period; exercise classes, sleeping and just going about my normal day.
    I can’t rave about them enough to my friends and to my daughter. I am encouraging her to try them as I am sure, like me, she won’t look back.

    I love your mission and I love your products.

    Thank you

    I love these

    I was so hesitant about period pants, but these are life changing. I've found they help my day 1 cramps too. They're super comfortable and are so easy to rinse. I thought it would be awful, but it's not. After rinsing I let them dry and there's no odour whilst waiting for my wash load to build up enough to get them cleaned. I'd recommend sizing up for a little more comfort though!

    Great but very warm

    These are great and give me a good protection to wear for a whole day. I had them on at work for 8 hours under fitted culottes and I felt comfortable. I found them a bit warmer than I would like for summer but they will be perfect for the rest of the year.
