NIXI Underwear started life as BP3 in 2019. Mum of 6 Kelly Newton was sick of little bladder leaks pausing her play on the hockey field. After dealing with incontinence brought on by childbirth and then early menopause, Kelly had tried every pad and knicker on the market and hated the way they looked and felt.

She wanted absorbent knickers that would look great under gym leggings and make her look and feel amazing - without worrying about leaks. She designed her first pair of knickers and took the plunge into starting the business. The rest is leak-free history.

Kelly soon realised that the knickers were not only a great solution for her little bladder leaks, but could also help reduce the amount of plastic waste that came with traditional period products. Coni Longden-Jefferson joined the business in 2020, bringing with her a deep passion for plastic-free periods and helping Kelly take the next step in the brand’s growth.

In 2022 they rebranded as NIXI Body - same amazing knickers, same wonderful team - just a brand spanking new name and look, marking an exciting evolution for the business.

The name NIXI comes from a group of Greek goddesses who were known to support women across various reproductive health stages - but particularly through childbirth. They were often depicted as squatting (something we’ve occasionally had to do out in the wild when our weak bladder has gotten the better of us!) so the team felt it was the perfect name for their knickers!

The rebrand also brought with it a more focused mission - keeping women moving through menstruation, motherhood and menopause. A desire to stay active was the biggest driver for Kelly to design her first pair of leak-proof underwear back in 2019. The team knows the massive impact that exercise can have on women’s mental and physical health - whether dealing with PMS, the challenges of having a new baby or navigating menopausal symptoms. NIXI can now be found in sports and eco stores all around the country and has a growing and loyal customer base - from UK sportswomen to new mums in New York!
