Here are 5 things we love about Sisters Republic underwear:

sisters-republic-uk

They measure between 1mm and 3 mm in thickness so are 3 times thinner than pads but offer the same absorbency

sisters-republic-uk

They quickly wick away the moisture, so you stay dry and comfortable

sisters-republic-uk

They absorb the equivalent of 1 to 3 pads for guaranteed protection for up to 12 hours

sisters-republic-uk

The anti-bacterial fabric ensures perfect hygiene all day long and keeps odours at bay (unlike with pads or towels!).

sisters-republic-uk

Thanks to an impermeable polyurethane barrier, our underwear is totally leak-proof

1.

MOISTURE ABSORBENT LAYER

The high degree of absorption is down to the 1 or 2 thin layers of technological fabric with highly absorbent and anti-bacterial properties (depending on the level of absorption chosen). The liquid is drained inwards and surface moisture is quickly wicked away to prevent any odour and dampness.

2.

LEAK-PROOF WATERPROOF LAYER

The waterproofing element comes from a thin layer of coated fabric that is both perfectly watertight and highly breathable.

3.

SOFT AND BREATHABLE LAYER

The reason you feel so comfortable is a clever mix of nylon and elastane, which results in a soft and resistant material that hugs the body's shape while letting it breathe. This same fabric is often used for sportswear.
