A gusset is essentially a liner. It’s where you’ll find our leakproof technology. It’s built into the crotch section of the underwear.

I wear these to protect against light bladder leakage and hey are seriously a game changer. I can walk around all day, take long buses (that don’t have bathrooms! 🫢), go to the gym and never feel self conscience about leaks. I used to use liners (reusable ones and disposable) but, aside from needing to carry fresh and used ones around or adding to the global garbage crisis, they never made me feel as “safe” and confident as these underwear. This style in particular is literally just like my regular underwear - no extra bulk anywhere, which is great once you’ve hit a “certain age” and temperature regulation is KEY! These are the “secret, sexy undies” to help you feel confident and unstoppable 🙂.
