Technical information


To determine whether a fabric is breathable, we measure its evaporative resistance (test based on standard ISO 11092).
The lower its resistance, the more the fabric will let water vapour produced by the body escape, and therefore the more breathable it is.
For example: RET < 9 = extremely breathable fabric.
