Bamboo underwear and what the OEKO-TEX label covers
Short answer: OEKO-TEX Standard 100 means the fabric has been tested for a catalogue of substances harmful to health. It says something about what is not in the fabric, not about how it was produced.
What the label tests for
The certification tests the finished fabric for residual chemicals above set limits. It covers dyes, heavy metals and a range of other substances. See what OEKO-TEX Standard 100 means.
What it does not cover
The label says nothing about working conditions, water use or how the fibre was made. It is a product test, not a production standard.
Why it is relevant for underwear
Underwear lies against the skin all day, and that makes residual chemicals more relevant here than in an outer jacket. See bamboo underwear for men.
Where you see it
The certification is stated on the product page for the items that have it. See OEKO-TEX certified items.
Other labels
FSC covers something else, namely where the raw material comes from. See what FSC means.
