Realizing a sustainable future: Development of the new material “Techfill Breath Thermo”

At Mizuno, we have established a “Sustainable Materials Procurement Policy” to protect the global environment, which we incorporate into our product creation.

We are excited to announce the creation of “Techfill Breath Thermo,” a groundbreaking material that offers superior warmth compared to down.^*¹ “Techfill Breath Thermo” not only surpasses down in heat retention^*¹ but also maintains its insulating properties when wet, providing consistent warmth across various weather conditions.

*1　Based on Mizuno’s research. Thermal insulation properties were compared using 20x20cm samples with the KES Thermo Labo II in an environment of 20°C and 65% relative humidity. Test material: “Techfill Breath Thermo” cotton. Comparison material: Down (90% down, 650 fill power).

Traditionally, down products are made using waterfowl feathers. However, with the development of “Techfill Breath Thermo,” a new material that surpasses down in warmth, we aim to promote a shift away from down usage. This initiative is designed to support animal welfare^*² by reducing reliance on animal-derived materials.

*2　For animal-derived materials, Mizuno does not use fur (real fur), and for natural leather, we use only rawhide that is a by-product of livestock and rawhide of exterminated noxious animals. Mizuno also does not use leather from endangered species or reptile leather. For feather filling for clothing and other items, we are working to use down and feather sourced from animals raised in an animal-friendly manner.

We will continue to promote the use of sustainable materials, considering what impact materials used by us have on society and the environment, and fulfill our responsibility for the global environment through product lifecycle.
