MadeBy:Cotton

- Recycled cotton: class A- In conversion cotton: class B- Organic cotton: class B- Conventional cotton: class E

Spandex (Elastane): class ENylon

- Mechanically recycled nylon: class A- Chemically recycled nylon: class B- Virgin Nylon: class E

Polyester- Mechanically recycled polyester: class A- Chemically recycled polyester: class B

Conclusion:Nike Making App & Higg index:Only polyester has a better MSI score at both the Nike Making app as the Higg index score.The other materials score very low on the MSI score.

MadeBy:Most of the materials scored very low at sustainable. But if you recycle the polyester, cotton and nylon the materials will score higher at the fiber benchmark (class A, class B). Spandex (Elastan) had the lowest score (class E) at the fiber benchmark of all the used materials in the jeans.
