Our seamless leak-free underwear are ultra-thin, super smooth, and truly invisible. Designed with soft, lightweight nylon, they are super stretchy, and comfortable and can be worn seamlessly under anything. The breathable fabric keeps things nice and cool, and of course, our signature built-in tech absorbs moisture and prevents leaks, holding up to 40ml, for up to 12 hours.

Fit true to size. Due to the high elastane content, they can feel a little tight upon first use, however, they will loosen slightly after the first few wears.

Super-soft and breathable

Sustainably sourced

Facts behind the fabrics:

Our Seamless leak-free underwear is made using recycled nylon, made from pre consumer waste — like old water bottles and fishing nets.

So, you'll be diverting waste from landfill, while wearing light-weight, quick-drying, and super-smooth undies that keep you fresh and dry from leaks, all day.

Fluxies are machine-washable and reusable leak-proof underwear — providing a more sustainable alternative to single-use disposable products. Our incontinence underwear are built to completely replace single-use disposable products, with maximum comfort in mind. Every pair of fluxies underwear features our innovative built-in technology — a moisture-wicking top layer to keep you fresh & dry, an absorbent core layer to lock in the liquid, and an outer leak resistant barrier to prevent any leaks.
