Thermore develops sustainable garment insulation

The Thermore Group, a manufacturer of thermal insulation for performance apparel based in Milan, has launched Invisiloft, a slim insulation the company says combines “exceptional warmth with unprecedented thinness.”

Thermore says Invisiloft has been designed with postconsumer recycled materials to offer insulating capacity while minimizing bulk, marking a step forward in the design of technical garments. With padding considered less bulky than traditional material, Invisiloft can provide warmth without the typical volume of classic insulation, making it ideal for garments such as high-performance sportswear. The company adds that the new insulation can be applied to everyday wear because of its “packable nature,” allowing jackets and outerwear to easily be stored in small spaces without compromising functionality.

Invisiloft is made with 100 percent-recycled fibers from postconsumer polyethylene terephthalate (PET) bottles, and Thermore says it meets the needs of clothing brands seeking superior thermal performance combined with eco-friendly materials.

The company says Invisiloft is certified by the Global Recycling Standard (GRS) and is available in four weights, from 100 to 200 per square meter. The material adapts to any design, Thermore says, meeting different climate and comfort requirements. Additionally, the material is compatible with normal washing and dry cleaning.

In a news release, the company says, “Once again, Thermore reaffirms its position as a true pioneer in the textile industry, driven by innovation, performance, sustainability and durability; principles that have shaped the company’s history since its founding in 1972.”
