The sustainable & functional sherpa jacket

The Sherpa jacket is loved by everyone.
Soft, cosy… but often made from virgin polyester sourced from afar, and impossible to recycle.

At Zèta, we kept what truly matters: comfort, warmth, and style — in a 100% recycled version with a modern cut, crafted in Portugal by skilled artisans.



A timeless jacket designed to last

We designed this jacket to last.
Not just for a season, nor for a passing trend. But to accompany you for years to come, season after season.

Unisex, versatile, and timeless, it is an essential wardrobe staple.
From mid-season to winter, it can be worn almost all year round: light when the weather is mild, and warm when it turns cold!

We also tested it, re-tested it, wore it, washed it, and wore it again.
In the wind, rain, and cold. Over a jumper or under a coat, paired with jeans or smarter trousers. It has seen it all, weathered it all, and never faltered.

It is a jacket that adapts to you, not the other way around!

Warm, soft, and more responsible

So, for those who love shearling-style jackets (and also love the planet), we have completely redesigned it.
We wanted to keep that warm, soft, and enveloping feel we adore, without compromising on materials.

No more virgin polyester from the other side of the world: ours is made from recycled polyester, lined with 100% cotton.

Available in three colours, as a fleece jacket or a sleeveless vest, it suits every style. Its straight, slightly oversized cut gives it that perfect drape: roomy enough to layer over a jumper, yet structured enough to keep a polished look.

100% cotton inner lining: natural, soft, and breathable.

Inside pocket: Ultra-practical for keeping your essentials close at hand.

The Zèta label: the house's signature.

100% recycled jacket: The jackets are made from recycled polyester and crafted by skilled artisans in Portugal.

Your questions about Sherpa jackets

What is a Sherpa jacket?

Sherpa, also known as a faux-shearling jacket, offers the look of sheep's wool without any sheep involved. It was created to provide warmth while remaining lightweight. Originally designed for the mountains and the outdoors, it quickly became a winter essential, now revisited with cuts and materials that make it effortless to wear every day.

Which jacket size should you choose?

This jacket features a slightly oversized cut; for a more fitted look, please choose one size down from your usual size.
Eduardo is 1.82 m tall and wears a size M.
Louisa is 1.75 m tall and wears a size M.

How do you style a Sherpa jacket?

The sherpa is an exceptionally versatile piece. You can wear it as a light jacket over a T-shirt or shirt, layer it over a jumper, or slip it under a coat on colder days. Its slightly oversized cut makes it easy to style without looking overly technical. Paired with jeans, wide-leg trousers, or even well-chosen joggers, it suits every occasion. The idea is for it to effortlessly fit into your daily life.

How do you wash this fleece?

The best way to care for it is to machine wash at 30°C on a gentle cycle, then air dry. There is no need for a tumble dryer, which would damage the fibres and consume a lot of energy. The goal is to preserve its softness and shape while being kind to the planet. And since it does not readily hold odours, simply airing it out between wears is often enough.

Is Sherpa warm?

Yes, that is its very purpose.
Its plush, teddy bear texture provides excellent insulation against the cold while remaining breathable.
Unlike a puffer jacket, it is lighter, more flexible, and far more comfortable for everyday wear.
The fleece jacket is this winter’s must-have!

What is the best jacket for cold weather?

The one that keeps you warm, of course — without making you feel like you are wearing a duvet.
The ideal piece is well-insulated, breathable, and easy to layer.
The Sherpa ticks every box: soft, warm, and lightweight all at once.
