Best Naja Alternatives - 2025

The most comfortable underwear

The only period-proof underwear. Because every person with a period deserves peace of mind. Thinx is a New York based company that makes feminine hygiene products. The company has three brands Thinx, Speax and. Thinx is a underwear that can be worn during menstruation as a substitute or a supplement to traditional feminine hygiene products.

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.
