Good to know

Your questions, answered

How does Rudie leakproof underwear actually work?

An absorbent, leak-resistant gusset is bonded straight into soft bamboo. It wicks moisture away from your skin, holds it in the core, and a hidden barrier layer stops it passing through. No inserts, no pads, no liners, and nothing to throw away.

Which style should I choose?

Thong for lighter and liner days, brief for everyday light to moderate days, and the high-waist brief for your heaviest days and overnight. Most people wear a mix across their cycle.

What's in the gusset?

It's a thin, multi-layer stack: a soft cotton top against you, a bamboo terry core that absorbs and holds, and a leak-resistant barrier with seaweed fibre that keeps it off your clothes.

What is it made of?

92% organic bamboo and 8% elastane in the body, with a thin, multi-layer leak-resistant gusset. Bamboo is soft, breathable and naturally moisture-wicking, and it's up to 70% less synthetic than the industry standard. We print the exact numbers, no rounding down.

What size should I choose?

Choose your usual size. Rudie runs in sizes 6 to 14, true to size, with a size guide on every product page. Between sizes? Size up for a relaxed, no-dig fit.

How do I care for them?

Rinse in cold water after wear, machine wash cold on a gentle cycle, and line dry. No fabric softener, no bleach, no tumble dry, so the fibres and gusset keep performing for years.
