Two villages in Portugal makes your clothes

Near Porto, in Portugal, two small family businesses work side by side for us. The first, in one village, knits our organic cotton from scratch and dyes it to our specifications. The second, in the next village, cuts and sews. We have been visiting both every year since 2009. We know the people by name. We share meals when we visit. They have watched our collections grow alongside their own children.During the Covid years, when organic cotton and bamboo became briefly impossible to source in Portugal, we found a second family workshop in Turkey — also ethical, also certified, also personal. About 5% of what we make passes through their hands today. The Mizar Kimono and a few Lilac pieces from past collections come from there.Most yoga brands buy fabric from a market — pre-made rolls, ready to cut. We don't. Every meter of jersey we use is knitted from scratch to our specifications. That is why the Sohang feels the way it does. That is why a five-year-old pair softens instead of wearing thin.A slower way of making clothes. Sometimes inconvenient. Always worth it.

The slow choices we keep making for sustainability

Sustainability for us is not a marketing department. It is a series of small, sometimes annoying choices we have made since 2009.We chose certified organic cotton when it was 40% more expensive than conventional or plastic fabrics. We still pay that premium today. We grow without external capital which means we cannot afford to overstock, so we don't. We use every meter of yarn we order, even when it means smaller runs and longer waits. We are 100% self funded and all the money is placed in ethical funds in a local bank.We focus on evergreen pieces, the Sohang, the Amrit, the Amba instead of seasonal collections. Some of these designs are over a decade old and still our bestsellers. A garment worn for ten years on a body is the most sustainable thing a fashion brand can make.Our fabrics are dyed with processes gentle enough for a baby's skin. We package in either recycled or biodegradable bags. We ship from our small warehouse in Cully (Switzerland) or our partner in Germany, never overseas.We don't tick every box. We are not perfect. But these are the choices we make, and we make them visible.

What materials we use?

We work with three fabrics. Three. Not thirty.Brushed Organic Cotton Jersey (220g, made in Portugal) soft, slightly thick, with a peach-skin touch. Our flagship. The Sohang, Yamala and Mahan are knitted from this.Mercerized Organic Cotton Jersey (180g, made in Portugal) lighter, smoother, with a subtle natural sheen. Our new Essence Collection uses this for models like Ankaa, Nashira, Maia.Bamboo Viscose blended with Organic Cotton (made in Turkey) cool, breathable, fluid. Used for the Lilii pants and the Mizar Kimono. Bamboo regrows in three to five years, without replanting and without irrigation.Most pieces include around 8% certified elastane, enough to hold shape over years of wear, without losing breath.We use every meter of yarn we knit. What we don't sew, we save for repairs and samples. Nothing goes to waste.

Three generations of women to design

Three generations of women.My grandmother Johanna sewed evening dresses by hand. Long, careful, beautiful work, a kind of patience that has all but disappeared.My mother, Cornelia, learned from her. In 2009, she founded Breath of Fire. The very first piece she designed, the Sohang, was created on the floor of her living room in Switzerland, with a yoga teacher friend named Christina. It is still our flagship today, seventeen years later.Today, I ( Pernelle) run the brand. I do not redesign what works. I extend it. The Essence Collection, launched in 2025, sits beside the Evergreen line. New silhouettes, same intention.We do not design for trends. We design for the body in practice, for the moment when the breath deepens, when the posture lengthens, when you forget what you are wearing.That is the test of a piece. Forgetting it on. Returning to it.

Sweet, cozy, and effortlessly flattering — a loose-fit top that moves with the body without ever clinging.

The Cosma Loose Fit Shirt was created by Cornelia Kauhs, founder of Breath of Fire. Cornelia wanted an easy, adaptable essential — a piece that brings softness, coverage and freedom of movement to slow practice and everyday life. A discreet ribbon hidden inside the hem lets you adjust the shape: leave it loose for a flowing silhouette, or tie it in for a more defined line at the hips.

What makes it unique

Soft bamboo & organic cotton jersey — 200 g/m², breathable and naturally elegant on the skin.
Hidden adjustable hem ribbon — wear loose and flowing, or tie in to define the waist.
Balanced loose-fit cut — generous shoulders, gentle drape, never clingy.
Three quiet shades — Dark Purple, Lilac and Mint.

Best for

Gentle, slow practice and restorative yoga
Layering after class, over a bra or close-fit top
Everyday wear at home and quiet days out

Honest note on practice style

The Cosma is a loose, draping top — not built for inversions or dynamic vinyasa where you want fabric to stay close. For a close-fit longline option in organic cotton, see our Sohang Yoga Top. For long sleeves with thumb loops in mercerized organic cotton, look at the Lunara Longsleeve Shirt.

Honestly made — the story behind our Evolve collection

This piece comes from our Evolve collection — and there's a small story behind it. In 2019, when Covid disrupted supply chains, our family atelier in Portugal lost access to certified organic cotton. To keep the brand alive and honour our promise to natural fibres, we found a wonderful partner workshop in Turkey — fully solar-powered, certified, and run with the same ethical care we hold dear. We were genuinely happy to produce there.

Today, we have returned to our original Portuguese family atelier for the rest of our collections. The human warmth, the respect for skilled Portuguese artisans, and the quality we find there is something we have not seen anywhere else in the textile industry — and that's where our heart remains. Since 2009.

Material: 68% bamboo viscose + 28% organic cotton + 4% elastane.
Fabric: Bamboo–organic cotton jersey, 200 g/m².
Feel: Soft, breathable, gently draping with a touch of stretch.

Styling tip

Wear it loose over our Vega Leggings for a tonal Evolve look, or tied in at the waist with our Sohang Pants for a softer everyday silhouette.

Between two sizes? The Cosma has a loose-fit cut — the smaller size keeps a closer-to-the-body drape, the larger one a more relaxed flow.

Care

Machine wash at 30°C with similar colours. Air dry flat, no tumble dryer. The bamboo–cotton jersey settles beautifully with each wash.

Size & Fit

Runs true to size with a relaxed, flowy silhouette. Choose your usual size for ease and coverage. If you’re between sizes and prefer a more fitted look, size down; for extra drape, size up. The adjustable hem ribbon lets you fine-tune the shape to your preference.

Combine with pieces from the same collection for a polished look:

Aurora bra Lilii Pants

The soft layer that completes the outfit

The Cosma Shirt was designed to sit naturally within a considered set — a piece that brings softness and ease to silhouettes built for movement. Paired with the Lilii Pants and Aurora Bra, it completes an ensemble shaped around comfort, breathability, and quiet balance.

Across the pieces, bamboo-based fabrics create a shared language: light, fluid, and gently cooling on the skin. The result is clothing that feels comfortable over long hours, adapting effortlessly from practice to everyday moments. Together, the shapes remain relaxed yet intentional — offering support where needed, openness where it matters.

The Cosma shirt layers easily over the Aurora Bra, adding coverage without weight, and flows naturally with the wider cut of the Lili Trousers. The combination encourages freedom of movement and versatility, allowing each piece to be worn alone or together, depending on the moment.

Rather than standalone items, these pieces form a thoughtful wardrobe — designed to move, layer, and live with you. Yoga clothing rooted in natural materials, flexible proportions, and a calm approach to presence, both on and beyond the mat.
