Best Period Undies Out There!

I’ve tried other period panties but these have protected me during the heaviest flows. Takes longer to hang dry but still worth it. Thank you for making me feel less stressed!

Practical

These undies were larger than I expected. Even with the lace detail I felt frumpy in them. They did the job as night flow protection, no leakages & comfortable. I don't think I will be wearing them during the day though.

So great to be free of strings and wings!

I love these pants! I may still need a tampon on my heaviest day - experimenting at the moment - and I prefer a panty liner on the lightest days as the pants are quite substantial, but for all other days they are truly a blessing.

Really do work

I bought these initially as back up on heavy days but on my 2nd period I used them alone. No leaks, really comfortable and I felt secure. Wash well but take days to dry either on line or on warm radiator. Need to have about 6 pairs per cycle to allow for this. Would also like more colour options - nude perhaps?
