Why I made Nyth

It started with the small surrenders. A cough in the queue. A sneeze I braced for. A laugh I cut short. Bit by bit I got smaller cancelling plans, staying in, planning every day around the nearest loo. Everywhere I looked, the answer was the same: wait, it'll pass, wear something beige and clinical in the meantime. Nothing was made for women like me so I started making it myself. Nyth is everyday underwear for the leaks that arrive without warning. It looks and feels like your own, and it lets you stop planning your life around a "just in case."

In their words

" ★★★★★

I'd stopped going to my gym class, I just didn't trust myself. Wore these for the first session back and didn't think about it once. That's the whole point, isn't it. Not thinking about it.

I wear light trousers now, which I hadn't done in years. No line, nothing showing, and no smell — that was the bit I worried about most.

Finally a brand that gets what this stage actually feels like. Nothing beige, nothing clinical, nothing that makes you feel old. Just lovely things that quietly do their job.
