NuStretch Brief - One Size

Fluxies are a total replacement for disposable products, such as pads, tampons, liners, and cups. Our NuStretch one-size undies are designed for moderate to heavy flows, absorbing up to four tampons worth of flow. For most flows, they can last all day!

Our new one-size leak free underwear is available in One which fits UK sizes 6-16 and One+ which fits UK sizes 18-30.

fluxies NuStretch One-Size Period Pants are made from micro-fibre and elastane, a super soft material that offers you protection and coverage from all life's leaks.

You can wear your fluxies for as long as your flow allows. Every flow is different, and the type of absorbency you choose will affect how long you can wear your fluxies. We recommend you change your period underwear daily, just as you would with normal underwear.

Absolutely not! We have always focused on creating products that are safe for the environment and end-users (you!). We partner with manufacturers that regularly carry out testing, and in addition, we conduct independent, third-party testing by UK company Bureau Veritas. We are pleased to report that no detectable levels of PFAS have been found in fluxies period underwear.

Since launching five years ago, we have never added stain-resistant or water-resistant chemicals to our products. Instead, we choose fabrics with inherent moisture wicking, absorbing, and leakproof qualities, so they don't need chemical treatments which can contain PFAS.
