Olly's products are certified by the Global Organic Cotton Standard (GOTS). Next to organic cotton, Olly uses recycled lace or TENCEL to reduce waste and resource-use.

To reduce transport emissions, all of Olly's production takes place in Europe: Hungary, Spain, Portugal, and France. Recycled materials are sourced from Europe as well, only the organic cotton comes from outside Europe.

Olly's packaging is plastic-free, relying instead on cardboard and avoiding any unnecessary plastic inside the box.
