On Core Run Sock Mid 2-Pack

4% Elastane: used in combination with other materials, especially for its excellent flexibility - its fiber can stretch up to three times its normal length and then return to its original state.

45% Recycled polyester: An ecological alternative to conventional polyester, most commonly produced from used PET bottles or industrial plastic waste. Through the processes of crushing and melting, a new fiber is created that possesses identical functional properties to virgin polyester but with a significantly lower ecological footprint (consuming 59% less energy). The material excels in high strength, low weight, and the ability to wick moisture away extremely quickly. It is resistant to UV radiation, does not wrinkle, and retains its shape even after numerous washes. In modern streetwear, it serves as the foundation for technical jackets, jerseys, and accessories.

51% Organic cotton: Grown without the use of synthetic pesticides, herbicides and chemical fertilisers, making it an environmentally friendly alternative to conventional cotton. The entire growing process uses natural practices that conserve water, maintain soil fertility and protect the biodiversity of local ecosystems. For the end user, organic cotton is exceptional in its high quality and purity of fibre, which is free from chemical residues. This makes the material incredibly soft, breathable and hypoallergenic, which is especially appreciated by people with sensitive skin or allergies. By choosing organic cotton products, you are supporting sustainable agriculture and healthier working conditions for growers.
