The Inner Structure: Powered by Plants, Light by Nature

Now for the warmth.

Inside is BioPuff® — an alternative to both synthetics and feathers, developed by Ponda, a biomaterials company working where few fashion brands think to look: the wetlands.

Our filling comes from typha, a fast-growing aquatic plant.

You might know it as cattail. But in this context, it becomes something else entirely: structure, insulation, and intelligent design.

Why it matters:

• It’s renewable, fast-growing, and doesn’t compete with food systems.
• It mimics the warmth-to-weight ratio of down.
• It’s 100% biodegradable — breaking down faster than typical fills, thanks to its 40% plant, 60% recycled poly blend.
• Each kilo saves over 42kg of CO₂.

BioPuff® holds warmth the way nature intended — through airy structure, not dense stuffing.

It’s light. Breathable. Winter-grade.

And not a single feather is plucked.

The result?

Insulation that adapts like a natural system: warm when it needs to be, breathable when it should be.

If you’ve ever wondered whether a puffer could be light, cruelty-free and still cold-weather ready, this is your answer.

The Feel: Nature, Refined

The jacket is lined with organic cotton, and crafted in Portugal by specialists who understand that sustainability means nothing if the garment doesn’t last. Our factory runs entirely on green electricity.

The outcome?

A puffer that breathes, insulates, and wears like something you’ve already owned for years.

(And will want to keep for just as long.)

No shiny, squeaky shell.

No heavy synthetic padding.

Just soft structure, airflow, and fibres that know what they’re doing.

Why We Made It

Because we wanted to prove something. 

A jacket that holds warmth like down, moves like a knit, and leaves behind less of everything: weight, waste, water.

But more than that, it’s proof that collaboration and nature are the future of fashion.

That when regenerative farming, textile science, and biomimicry sit at the same table, they don’t just innovate — they evolve the brief entirely.

Manteco brought decades of textile mastery.

Ponda brought the ingenuity of wetlands.

We brought a relentless belief that nature doesn’t need to be outperformed, it needs to be understood.

Together, we made something none of us could’ve made alone.

A new standard in outerwear.

A reminder that sometimes the smartest designs begin with dialogue.

Because the future of fashion won’t be built by force.

It will be shaped like this Wool Puffer Jacket: softly structured, full of space, and stitched in collaboration.
