Thermore and Patagonia Partner on Circular Insulation Push with New Heyes Peak Collection

Patagonia has long been regarded as one of the outdoor industry's most influential sustainability pioneers, while Italy's Thermore has spent decades building a reputation as a specialist in advanced thermal insulation. Their newly announced collaboration brings the two companies together for the first time, with Thermore's EVOdown insulation debuting across Patagonia's new Heyes Peak collection.

The partnership is significant not only because it links two recognised names in outdoor apparel, but because it reflects a wider shift across the sector towards synthetic insulation systems built around recycled content, traceability and reduced environmental impact.

Designed as a transitional-weather range, Patagonia's Heyes Peak collection spans five men's and women's styles, including jackets, parkas, hooded models and a 3-in-1 parka. The collection has been developed for everyday use through changing seasonal conditions, combining breathable warmth with a more casual aesthetic than highly technical alpine-focused outerwear.

At the heart of the collection is Thermore EVOdown, an insulation manufactured entirely from recycled PET bottles. The material is designed to replicate some of the softness and loft associated with natural down while retaining the durability, moisture resistance and easy-care characteristics of synthetic fills. EVOdown is certified to OEKO-TEX Standard 100, the Global Recycled Standard and Bluesign standards.

The flagship Heyes Peak Jacket combines 80g EVOdown insulation with a shell fabric made from NetPlus, Patagonia's material derived from 100% post-consumer recycled fishing nets. The garment is also finished with a durable water repellent treatment made without intentionally added PFAS, continuing Patagonia's long-term effort to reduce reliance on fluorinated chemicals. Styles across the range are manufactured in a Fair Trade Certified factory.

While the partnership may appear to be a straightforward supplier agreement, it highlights a broader transformation underway in the insulation market. For years, brands have faced a difficult balancing act between performance, cost and sustainability. Natural down remains prized for its warmth-to-weight ratio, but concerns over sourcing and animal welfare have driven investment into synthetic alternatives. At the same time, traditional petroleum-based synthetic insulations have come under scrutiny because of their environmental footprint.

As a result, recycled insulation technologies have become one of the fastest-growing segments within the outdoor apparel supply chain. Thermore, headquartered in Milan, has positioned itself at the centre of this transition, developing insulation technologies that increasingly rely on recycled fibres and circular-material strategies. The company's customers span both technical outdoor brands and fashion labels seeking lower-impact thermal solutions.

For Patagonia, the introduction of EVOdown appears consistent with its wider materials strategy. Over the last decade the company has prioritised recycled fabrics, Fair Trade manufacturing and reduced chemical impacts, often using its buying power to encourage innovation throughout its supply network. The decision to introduce a new insulation partner suggests confidence that EVOdown can meet both performance expectations and Patagonia's stringent environmental requirements.

Laura Beachy, Senior Vice President of Global Marketing and Communications at Thermore, described the launch as evidence that "high-performance insulation and genuine environmental responsibility aren't a trade-off."

Joe DiGirolamo, Thermore's Director of Sales, said Patagonia's selection of Thermore as insulation supplier for a five-style men's and women's collection demonstrated the company's position within the sustainability-focused performance materials market.

The collaboration also arrives at a time when consumer demand is moving beyond simple recycled-content claims. Increasingly, outdoor customers are scrutinising material origins, supply-chain transparency and product longevity. In that environment, partnerships that bring together certified recycled insulation, recycled shell fabrics and PFAS-conscious manufacturing are becoming a key competitive differentiator.

Whether the Heyes Peak collection becomes a long-term platform for the two companies remains to be seen. However, the launch signals where outdoor apparel innovation is heading: products engineered not only for warmth and comfort, but for measurable reductions in environmental impact throughout the supply chain.
