HANDWASH: After use, rinse with cold water.
MACHINE WASH: Pop your WUKA with similar, dark coloured garments and wash at 30 to 40 degrees. Don't use fabric conditioner.
We suggest that Perform Collection and Re-purpose Collection styles should be washed cold. We also recommend washing any WUKAs with mesh or lace in a wash bag. This will help prolong the life and the strength of the mesh.
LINE DRY: Air dry your WUKA Period underwear outside on the line or indoors on an airer. Don't tumble dry it.
For the first 40 days after you receive an order we offer a 100% satisfaction guarantee on your first pair of WUKA underwear, this allows you to try them hassle free. If they don’t fit then you are welcome to exchange for a different size or get a full refund.

super comfortable.
These are super comfy and offer good protection overnight. The quality is really great. The only slight negative is I find the legs ride up a bit, but this may be because I need to size down. I got a M and I am a 10-12, the fit is generous so could have potentially gone for a S.
Before I tried these i always had some leaks overnight and had to put a towel underneath me but since trying them i have had no leaks at all and do not need the towel at all.
Fit well. Are yet to try out for absorbency.
