  1. Vivo Performance: Eco Insulation

Vivo Performance: Eco Insulation

Vivo Performance: Eco Insulation is a European made polyester insulation, which is developed to maintain good breathability while keeping you warm. It comprises a patented perforation with very small holes within the insulation, increasing breathability by 30 % and allowing moisture to escape, thus providing more comfort for the wearer. The holes are of a unique size: Visible enough to notice a difference but too small to allow air to circulate; they maintain the full insulation properties of the material. The small holes also provide a 4-way stretch within the insulation with a fast recovery which allows it to be combined with performance fabrics.

Vivo Performance: Eco Insulation is made in Europe from 93 % recycled fibers. The fibers are extruded from used plastic bottles and then recreated into insulation.

Polyester normally uses fossil resources for its production. By re-using existing material streams we can save fossil resources and reduce the energy demand as well as climate emissions.

The reason why mainly PET bottles are used is due to their availability and their purity in terms of material type. No other waste stream offers that big volume of basically the same identical raw material without any impurities from other material inputs. Furthermore, we can also reduce plastic waste as these material streams are being utilized again.
