US yarn manufacturer Unifi has partnered with DuPont Biomaterials and outdoor specialist Youngone on a new collection of insulation products that offer sustainable options for cold-weather garments.

The new EcoLoft eco-elite insulation collection from Youngone, a global manufacturer of outdoor and athletic clothing, textiles and footwear, utilises DuPont Sorona renewably sourced fibre and Unifi Repreve recycled content.

The collection, the parties claim, is the first post-consumer recycled product that also incorporates bio-based materials for insulation. It features three products with various benefits that all offer a reduced environmental footprint without compromising on insulation performance.

“This EcoLoft collection will elevate sustainable, high-performance insulation solutions for the outdoor market and offer brands a versatile option for cold-weather products,” says Renee Henze, global marketing director for DuPont Biomaterials. “Unlike traditional down or synthetic insulation products, this offering optimises the use of recycled and renewably sourced content for best-in-class insulation solutions.”

The EcoLoft eco-elite insulation collection consists of:

  • EcoLoft ActiVe SR (35% Sorona and 55% Repreve) – A synthetic, vertically lapped insulation that combines the warmth-to-weight of down with breathability, improved vapour management while maintaining warmth, compressibility and soft comfort.
  • EcoLoft Flex SR (60% Sorona and 35% Repreve) – Maximised multi-layering of Repreve and Sorona fibres in the padding web create a lightweight, warm insulation designed for breathability and movement. With a lower basis weight, it offers flexibility, stretch and comfort ideal for the casual market.
  • EcoLoft Air SR (60% Sorona and 40% Repreve) – Voluminous natural-down-like synthetic fiberfill for puffer jackets and similar products, with notable warmth, washing performance and vapour management for enhanced comfort.

Samples of the products will be available at the Outdoor Retailer Summer Market next week.
