Peace of mind

Being a woman of a certain age, I want to run and feel good, not be worried about accidents. These undies are the answer. Very comfortable and perfect to boost my bladder confidence.

THE SUSIE BLACK
Best exercise knickers EVER!

I bought these on a whim. Pricey I thought, BUT having worn them for gym workouts and running they are amazing and worth every penny. Im about to buy some more. Some other colours would be nice 😉

BUNDLE - 3 PAIRS SUSIE BLACK
Game changer

I’ve tried other brands of pants with built in pads and they feel bulky.
These were fantastic, super comfy and very absorbent.
They wash well too.

Sarah Smith
THE SUSIE BLACK
Just what I needed

True to size, wash well, wore on period and no leaks. I wasn't sure about period knickers and wanted to give them a try, much easier for leaks and periods than pads when at the gym and sweating. feel confident in these and no leaks noticed. would recommend

THE SUSIE BLACK
Amazing

I can’t believe I didn’t know about these before now at 59 !!! They have changed my life.

Great pair of knickers!!

Brought these to wear in the gym for any oops moments, so comfortable & no cool
really comfortable

Jo M
THE CONI BLACK

Just received my first pair of the Susie underwear, they are the best knickers I’ve ever bought, no vpl and due to the seem at the back the under gusset starts far enough forward so you don’t feel like your wearing a thick pad, you can’t see it through leggings either, which was a win for me! I will be ordering more pairs of these..

THE SUSIE BLACK
Best nicks

Comfortable, good fit, wider crotch is great improvement on my previous buys from another label, love them.

Ann Pierce
THE POLLY
I love them

I’ve tried other products but Nixi are way better look and feel like ordinary underwear, I’m a size 12 they fit perfectly. I have 3 Susie, recently tried a Carla, definitely reordering these.

THE SUSIE BLACK
Relaxation

Started to buy Nixi for the odd bladder leak I’ve started to get. Knowing I have a safety net should it happen is such a relief. I can relax and enjoy what I’m doing without fear of embarrassment or discomfort.

Jude
THE CARLA CREAM LIGHT
So comfy

Bought two pairs (the Sarah and the Susie).
Really comfy to wear, not bulky and absolutely no VPL which is amazing.

Looking forward to getting some more, highly recommend.

Gemma
THE SARAH
Security and comfort

I now have 2 pairs of Susie knickers. I was new to period underwear when I bought these, and was a bit concerned about the possible 'wearing a nappy' feeling, but did not get that with the Susies. They are super comfortable, and have not leaked once, even after all day wear. I also use them for running, as I have reached that age where my bladder can't always be trusted, and again they have kept me completely safe.
I did find the sizing a little on the big side, I am a size 16, so when I bought a second pair went for a 14 and they are perfect. Will be investing in more!

THE LEAKPROOF UNDERWEAR OF CHOICE FOR SPORTY WOMEN EVERYWHERE

ADORED BY ATHLETES

  • These pants are amazing, I love that I can go about all my usual activities while knowing that I am covered on even the heaviest period days, while I protect the planet by creating zero single use plastic waste.

    Laura Crane - Surfer

  • Having tried them out I genuinely couldn’t recommend them enough! I wore them in the gym with leggings on, no VPL, no issues, and if I’m honest they’re so comfy I would probably wear them not on my period!

    Tammy Beaumont - England Cricketer

  • These period pants are the best invention ever. The Sporty girl shape makes them comfy and have no VPL and for someone that suffers with very heavy periods, they give me the confidence that I’m not going to leak mid training session or through the night.

    Kadeena Cox - Para Olympian

  • I loved the No VPL and the cute design, They are comfy to run in and, being pregnant, my pelvic floor has been on and off so these gave me more confidence. I love the positive effect on the environment of not needing pads or tampons. Total gamechanger.
