Sustainable Underwear – What to Look For

Short answer: Responsibly made underwear comes down to three things: a sensible material, credible certifications and a lifespan that means you buy less often. Bamboo viscose from certified bamboo is a good option, provided you also choose a quality that actually lasts for years.

Start with the material

Bamboo grows fast without irrigation or pesticides, but bamboo viscose is made chemically, and the process varies from factory to factory. That is why the word bamboo is not an argument in itself. See the range under bamboo underwear for women and look for the certifications.

Certifications you can check

A certification is the only part of the claim you can verify yourself. Oeko-Tex Standard 100 means the item has been tested against a long list of harmful substances, and FSC means the raw material comes from a forest managed under set rules.

Lifespan weighs more than anything else

An item lasting three years rather than one cuts consumption sharply whatever it is made of. That makes quality the most concrete choice you can make: a wide waistband that does not roll, flat seams and a fabric with weight in it. Cheap underwear is bought twice.

Count in cost per day worn

An expensive pair worn three hundred times is cheaper than three cheap pairs worn fifty times each. The same applies to the environmental sum. That way of counting is the only one that holds when two items look identical on the shelf and differ only in price.

Washing is a large part of the sum

A large share of a textile's total impact comes from use rather than from production. Wash at 30 to 40 degrees rather than 60, fill the machine, and skip the tumble dryer. That is the part of the sum you control yourself every single week.

Buy fewer and wear them longer

A bigger drawer paradoxically lasts longer, because each pair is washed less often. But a bigger drawer full of items you do not wear is waste. Buy by what actually goes on the body, and leave the colours and models you are unsure about.

Be sceptical of vague claims

Words without a standard behind them mean nothing, and they appear on many products. Ask instead what is certified, by whom, and what the certification covers. If that cannot be answered, the claim is marketing. See also bamboo underwear for men.

What you can do with what you have

Worn out underwear cannot be passed on, but it can be used as cleaning cloths instead of being replaced by kitchen roll. It is not a solution to anything large, but it is a small thing that costs nothing and that few people think of. See also guide to bamboo and the environment and bamboo and economy.

Frequently asked questions

What should I look for in responsibly made underwear

Material, certifications and lifespan. The certification is the only part of the claim you can verify yourself.

What does Oeko-Tex Standard 100 mean

That the item has been tested against a long list of harmful substances. It says something about the chemistry in the fabric, not about production as a whole.
