Focus on : Clean Denim // Seventy + Mochi


Up to two-thirds of garments impact on the environment is realised at the design stage so to reduce the impact on the environment, Seventy + Mochi source eco-friendly fabrics and components. It is important to the brand that the improvements they make to their products and processes are benchmarked and quantifiable, so they have their materials and facilities independently certified by third parties. Each pair of Seventy + Mochi jeans are made using denim from their own mill, ensuring transparency in social and environmental responsibility. All of the denims are made using a blend of GOTS certified organic and recycled cotton certified yarns from their GRS certified recycling plant, no virgin or non organic cotton is ever used. By using only their own yarns and denim they also dramatically reduce their carbon footprint as their facilities are located in the same geographical region.

Recycled cotton is Seventy + Mochi's hero fibre. It is repurposed from either pre or post-consumer cotton waste that would otherwise go to landfill. Using recycled cotton, as compared to virgin cotton in their denim gives an immediate saving of 98% of the energy used and 100% of the water used. This is huge and adds up to 8 bath worth of water per jean. The recycled cotton comes from their mill partner's in-house shredding plant which is a stones throw from the spinning facility and mill.


After recycled cotton the brands next love is organic cotton. The production of organic cotton fabric uses less energy, releases fewer greenhouse gases and due to the improved soil quality, uses significantly less water. The GOTS certification not only looks at the environmental impact of growing cotton organically but also the social standards for the workers and by purchasing organic cotton which is GOTS certified, you know that the people who create your fabrics are paid a living wage and fairly compensated for their hard work.


Hemp was added in Seventy + Mochi's collection and they haven't looked back. Hemp is an important fabric that has gained popularity in recent years due to its wonder properties that can benefit the environment when compared to other materials. It is a much less thirsty crop than conventional cotton, up to a quarter of the water in fact. It also used less land than cotton to grow in. Hemp is also know to enrich the soil it is grown in, it is very durable and the whole plant can be used with the leaves being ploughed back into the soil to replenish the soil fertility for the next crop. A short growing season and deep root system allows for aeration and constant improvement of soil structure. It really is a wonder crop!
The brand source their hemp from France, so although it has a longer distance to travel to their spinning facility they are assured by means of it's OCACIA certification that no pesticides, phytosanitary products, GMOs or irrigation are used in the cottonized process.
