Anyone out and about in the city needs a jacket that reliably warms and is lightweight. LangerChen's puffer jackets with Eco Down meet precisely these requirements and simultaneously demonstrate your responsibility for the environment and animal welfare. Instead of animal-derived down, LangerChen uses an innovative, recycled padding that combines comfort, function, and sustainability. Eco Down represents an animal-free insulation solution that modernly combines warmth and environmental awareness.
What does Eco Down mean at LangerChen?
LangerChen's Eco Down is a synthetic filling made from recycled polyester wadding that completely replaces down. It's sourced from used PET bottles and processed to develop a high loft (volume). This traps body heat in fine air pockets, providing even insulation.
Another advantage: Eco Down retains its shape, doesn't clump, and dries faster than real down. Even in damp conditions, the padding stays pleasantly warm—ideal for active urbanites on the go. Because LangerChen avoids animal-derived materials, its puffer jackets are not only functional but also ethically sound.

Functionality meets certified sustainability
The padding used in LangerChen Eco Down is manufactured using a resource-efficient process. Recycled plastics are cleaned, processed into regranulate, and formed into new fibers. This creates a closed material cycle that saves energy and reduces waste.
The GRS (Global Recycled Standard) guarantees that the materials used are truly recycled and can be transparently traced throughout the supply chain. LangerChen also works with the OCS (Organic Content Standard). This confirms the proportion of organically produced materials in a product and ensures full traceability. Thus, LangerChen stands for controlled, sustainable processes – from the raw materials to the finished jacket.
The materials of the LangerChen Eco Down Puffer Jackets are wind- and water-repellent, lightweight, and durable. High-necked collars, adjustable hoods, elastic cuffs, and two-way zippers offer protection from wind and weather. The intelligent construction optimizes the microclimate, making the jackets ideal companions for everyday urban life.
With Eco Down, LangerChen proves that modern outdoor clothing can perfectly combine functionality, sustainability, and style. Every LangerChen puffer jacket with Eco Down represents innovative materials, certified responsibility, and a conscious feel – for people who live urban lives and think sustainably.
