Feeling fab playing sports

Do what they say, I’ve played sports forever but have recently been feeling less confident while making sudden movements, think I’ve found my comfort blanket! Thanks

Coni Sporty High Waist Cream Knickers

These are the best fit and shape of this product type across main brands I’ve found so far, worked well, and didn’t feel too bulky especially at back like alot of these products. They survived the Eras Tour 😆💖

Peace of mind

Purchased some pants a while ago, but a house move and change of lifestyle has meant I needed some more and some bikini bottoms.... These are a perfect fit, offer me peace of mind and look good too. I followed the size guide and they are just right. Arrived quickly too.

Coni Sporty High Waist Black Knickers

Mind blowing! Like wearing normal knickers

I use leak-proof knickers for running. My old ones were bulky and I put up with it because, hey, they kept me dry.
These babies are so thin it’s hard to believe they work but they do the job 100%.
Next time I will get the 3-unit pack.

Polly High Waist Knickers

I bought these for my sister who lives abroad and doesn’t have availability to these wonderful knickers. I told her how much I love mine ( I wear them everyday and have many pairs) She asked me to order her more pairs as she absolutely loves them. They are great for us menopausal woman who love to exercise but suffer with bladder leaks. Thanks you again Nixi Body ❤️

Polly High Waist Knickers - won't buy any other brand again

A friend shared a review about these knickers and I've tried three other brands, and although the others have been ok they always seem a bit bulky. I've recently been diagnosed with Adenomyosis and I am in my late 40's so my periods are short but really heavy, hence trying this particular type of knicker.
I'm pleased to give these a full five stars and I intend to buy more. These are a great fit, really comfortable, not bulky, lovely design, easy to dry and I didn't feel any panic to wear them during the night. Loved them. I'd love to see them in different colours, like green or blue or maybe patterned. I intend to recommend them to anyone who will ask and I'm going to buy more and slowly replace the other brands I have.
I did have trouble with delivery, as my first order never arrived, but a quick email to customer services got me a quick reply and they sorted it.
Thanks, Nixi and Kelly.

LOVED BY

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.
