I love my THINX knickers. They are comfortable to wear and I even feel sexy in them due to the sleek, black style. The crotch is big enough that I don't leak out of the sides and they are not so padded that I feel I am wearing period underwear. I do have to wear reusable pads on my first 2 days, but after that I can switch to THINX for the rest of my period. I wish there was a UK branch so I didn't have to ship from abroad as this defeats the object of being environmentally friendly for me unfortunately.
