Why we went dark

The honest story behind the Rudie rebuild: why we stopped, what we changed in the fabric, and the one number we refuse to round down.

Rudie bamboo period underwear, the new range

Before this range launched, we stopped selling for six months. The old product was not the underwear we wanted Rudie to be, and we needed time to finish its replacement properly.

The work had already been going on for three years. Those six months were the final stage of the rebuild. Here is what changed, and what we want you to know about the pair you are buying now.

The body fabric, with the whole number included

Our seamless body fabric is 92% bamboo viscose and 8% elastane. Bamboo viscose is a manufactured fibre made using bamboo as its cellulose source. It is not raw bamboo woven into fabric.

The elastane supplies stretch. It is still a synthetic fibre, and we do not leave that part out when we describe the blend. A body made mostly from bamboo viscose is not the same as a garment made entirely from bamboo.

The gusset has its own job

The absorbent panel in the crotch is called the gusset. It uses a cotton top against your skin, a bamboo-and-cotton absorbent core and a leak-resistant barrier containing modal, seaweed fibre and elastane.

That mix is different from the main body fabric. The 92% figure does not describe every layer in a pair. Our materials guide takes you through the breakdown.

Choose the protection for your day

Our manufacturer reference absorbency ranges are 5 to 10 ml for the Period Thong, 10 to 15 ml for the Period Brief and 20 to 25 ml for the High-Waist Brief. They help compare our styles. They do not tell you exactly how many hours a pair will last on your body.

Choose for your flow, coverage and fit, and change if the pair feels damp or uncomfortable, leaks or no longer meets your needs. A lighter cut may suit one day and a fuller brief another. You can also use period underwear as backup to another product while following that product's own instructions.

For a closer look at the two brief cuts, read our Period Brief vs High-Waist guide. Choose a different cut when you want different coverage; do not assume you need a bigger clothing size.

The same body blend in a bra

Our Bamboo Wireless Bra brings that 92% bamboo viscose and 8% elastane body blend to a wire-free, seamless style. It has removable moulded pads, adjustable straps and a hook-and-eye back.

Leave the pads in for their shape and coverage, or take them out for a softer, less structured feel. The bra fit guide explains the details without promising that one style will suit everyone.

A routine you can repeat

Wash your Rudies before first use. After wearing period underwear, rinse cold until the water runs clear, then machine wash cold on a gentle cycle with similar colours. Air dry fully. Do not bleach, tumble dry, iron or dry clean.

Our care guide covers the washing and drying routine, including keeping a fresh pair ready while another is in the wash.

This is Rudie now

We rebuilt the range around a fabric blend we are happy to explain and a small choice of cuts with different jobs. That includes the body fabric, the gusset and where a pair's limits are.

You should be able to find those answers before you buy. That is the standard we want Rudie to keep.

Common questions

What is Rudie period underwear made of?
The body is 92% bamboo viscose and 8% elastane. The gusset uses a cotton top, a bamboo-and-cotton absorbent core and a leak-resistant barrier containing modal, seaweed fibre and elastane.
How absorbent is each style?
Manufacturer reference ranges are 5 to 10 ml for the Period Thong, 10 to 15 ml for the Period Brief and 20 to 25 ml for the High-Waist Brief. They help compare styles and do not guarantee individual wear time or protection.
How long can I wear a pair?
There is no fixed wear time we can promise for everyone. Flow, fit, coverage and the pair’s capacity matter. Change if it feels damp or uncomfortable, leaks or no longer meets your needs.
Is the whole pair made from bamboo?
No. The body is a bamboo-viscose and elastane blend. The gusset has its own materials, so the body-fabric percentage does not describe every part of the garment.
How do I wash my Rudies?
Wash before first use. After wearing period underwear, rinse cold until the water runs clear, then machine wash cold on a gentle cycle with similar colours. Air dry fully. Do not bleach, tumble dry, iron or dry clean.
