recycled X-breath Fabrics

save the earth by re-using resources!

Resource recycling and reusing is essential in minimizing impacts on environment. The recycled X-breath fabrics use recycled polyester as the shell fabrics, and recyclable polyester membrane as the breathable lamination. In addition to reusing resource, it also reduces energy consumption and CO2 emissions. After the end of life, the fabrics are recyclable.


  • With shell fabrics made of recycled polyester

  • With breathable membrane made of polyester

  • Being 100% recyclable

  • Enabling resource recycling to reduce energy consumption and CO2 emission

Sorona® fabrics, woven and knitted

renewably sourced™ polymer deriving from non-edible biomass

Affordable for you and the environment, our DuPont™ Sorona® fabrics combine exceptional performance with environmental benefits. The features are:

  • reduced CO2 and energy consumption,

  • dazzling color,

  • sensuous softness,

  • relaxing comfort,

  • easy care,

  • and UV resistance

DuPont™ Sorona® fabrics are made with renewable resources instead of petrochemicals, thereby reducing our dependence on oil - a finite resource. Production of Sorona® fiber reduces CO2 emissions by 63% compared to petrochemical-based Nylon 6 (polyamide).
