REDEFINING ATHLETIC LUXURY
We discovered merino wool's secret:
it's not just for mountains, it's for modern life.
While others chase synthetic trends,
we're pioneering natural luxury for your daily flow.
MERINO Q&A
Regular wool has coarse fibers (25-40 microns) that can irritate skinand feel itchy, requiring a base layer underneath.
Merino wool has ultra-fine fibers (16-24 microns) that are soft and comfortable against skin.
Flowool uses 16.5-17.5 micron superfine Merino, feeling silky smooth like a second skin.
Merino fibers have a unique structure that responds intelligently to body temperature:
When cold: Air pockets between fibers trap body heat, creating natural insulation.
When hot: Absorbs moisture and evaporates quickly, cooling you down.
When wet: Retains warmth even when damp (wet-warmth property)
That's why a single merino wool garment can be worn year-round.
Yes! Merino wool has natural antibacterial and odor-resistant properties:
How: Lanolin on fiber surface naturally inhibits bacterial growth.
Result: Stays fresh for 3-5 days of continuous wear.
Compare: Synthetic fabrics need washing after single use
Perfect for travel, sports, and outdoor activities.
Rarity: Merino sheep are only 3% of global sheep population.
Complex process: 30+ steps from farm to garment.
Superior performance: Warmth, breathability, odor-resistance, quick-dry.
Durability: Lasts 5+ years with proper care.
Lower total cost: Less frequent purchases and washing
Cost-per-wear makes it actually economical.
MADE WITH TRUST
Simple, responsible, reliable. The way natural performance should be. Designed with intention, made through trusted partners, and grounded in materials we believe in. Just performance that feels right, and lasts.
FLOW INTO WOOL
Why Flowool Chooses Merino Wool for Movement
Rethinking Wool Beyond Winter
For decades, wool has been framed in a very specific way. Cold weather. Warmth. Stillness. It’s often associated with heavy layers, static environments, and seasonal dressing. But this narrative only tells part of the story. At
Flowool
, we see wool—specifically Merino wool—as a material with untapped potential for movement. Not despite its natural properties, but because of them.
Movement Demands More Than Warmth
Movement is unpredictable. Body temperature rises and falls. Sweat appears and evaporates. Skin stretches, compresses, and recovers. A true performance material must adapt continuously—not, not lock the body into one state. Merino wool does exactly that.
Temperature Regulation: Adapting in Real Time
Merino wool naturally regulates temperature by responding to the body’s needs. When heat builds up, it helps release excess warmth. When movement slows, it maintains balance instead of sudden cooling. This adaptive behavior makes Merino especially suitable for activities that involve changing intensity—walking, training, travel, or everyday movement.
Moisture Management Without the Synthetic Feel
Unlike many synthetic performance fabrics that push sweat away aggressively, Merino wool manages moisture more subtly.Its fibers absorb moisture vapor from the skin and release it gradually, helping the body stay dry without creating stiffness or discomfort. The result is dryness that feels natural—not forced.
Odor Control That Works With the Body
Merino wool naturally resists odor by limiting the growth of odor-causing bacteria. This is not a surface treatment—it’s part of the fiber itself. For active wear, this means garments stay fresher longer, even with repeated wear. Less washing. Less wear and tear. Longer product life.
The Relationship Between Fabric and Skin
In motion, fabric doesn’t just sit on the body—it interacts with it constantly.Merino fibers are fine, flexible, and naturally elastic. They move with the body instead of resisting it, reducing friction and pressure over time.This matters most during long periods of wear, where comfort is defined by what you don’t notice.
Is Wool Anti-Performance?
The idea that wool is unsuitable for movement comes from outdated contexts — not from the material itself. When handled with intention, designed with precision, and applied to the right use cases, Merino wool performs exceptionally well. It’s not anti-movement. It simply requires understanding.
Performance Requires Thoughtful Material Choices
Not every
performance piece
can be made from 100% wool.High-intensity movement often requires structure, rebound, and stability—qualities that sometimes need technical fibers to support the body effectively. At Flowool, we push the wool content as high as performance allows. Because breathability, comfort, and natural touch still matter. This is not compromise. It’s an evolving design process.
Transparency as a Foundation
Every fabric composition we use is clearly labeled. Every blend has a purpose. Every decision is made with intention.We believe performance apparel should be honest—about what it is, how it’s made, and why those choices exist.
Movement Is the Proof
Flowool chooses Merino wool not because it fits a trend or a
category
, but because it performs when the body moves. When fabric adapts, supports, and disappears into motion—that’s when material choice truly matters.
Every Step Matters: How We Respect Wool and Craftsmanship
This piece was created in motion—captured in our factory exactly as it happens. No staging, no repeats, no polished sets. Just the real workflow behind a wool shirt built with precision, discipline, and a respect for thoughtful making.
Why We Show the Process
Sharing the production is not a marketing trick—it’s a way to make craftsmanship visible. Many steps of a wool shirt are subtle and technical, and the beauty lies in those details. By opening the process, you see the discipline that defines the final piece.
Seeing the Process Changes the Relationship With a Product
Watching the operators work is a different kind of education. Hands moving with instinctive precision. Wool draping in slow, natural curves. Machines humming—not not as symbols of mass production, but as extensions of skill. The shirt is assembled through dozens of micro-steps: clean cutting, controlled tension, steam shaping, reinforcement of wool panels, and the final checks that ensure the drape feels natural on the body. When you see these steps up close, the product stops being a “thing” and becomes a craft. This transparency is the foundation of trust. You deserve to know what you’re buying, how it’s made, and why it matters.

Why Embroidery Isn’t Just Decoration
Embroidery is often treated as an aesthetic touch. For us, it’s a signature of intention. Merino wool is soft, breathable, and inherently elastic, which means embroidery must be handled differently from cotton or synthetics. The tension, backing, stitch density—everything must be recalibrated so the wool maintains its shape without stress. In our factory footage, you’ll see operators measuring fabric stability, adjusting the embroidery frame manually, and inspecting every thread run under light. These adjustments protect the integrity of the wool while giving the shirt its character. It’s slow work, and we choose the slow way on purpose.
Balancing Performance and Wool: Our Approach
We work with Merino wool not because it is perfect, but because it is honest. In our performance line, not every piece can be 100% wool. High-intensity movement requires structure, rebound, and stability—qualities that sometimes need technical blends to deliver the support you actually feel during motion.
But we always push the wool content as high as performance allows—because comfort, breathability, and natural touch matter. This is growth, not compromise. Every fabric we use is clearly labeled. Every blend has a reason. Every choice is intentional. We’re committed to building performance apparel that respects the body and respects the material—without pretending we’ve already reached the final form.
Merino is naturally breathable, odor-resistant, and thermoregulating. It elevates performance when handled with care. But it also demands skill. Cutting, embroidery, seam pressing, shrinkage control—Merino responds differently at each stage.
Our manufacturing partners treat it like a material that deserves patience, not shortcuts. You can see that in the footage we captured at the factory: slow hands, careful presses, intentional handling. Natural fibers reveal everything—attention, intention, respect. And that honesty is exactly why we choose Merino in the first place.
So Why Pre-Order?
Pre-order allows us to avoid overproduction and invest fully in the craft. It ensures every shirt is made with intention, not speed. It gives the factory the bandwidth to slow down, isolate operations, and execute with accuracy. But most importantly, pre-order includes you in the process. Instead of presenting a finished product with no context, we open the doors. You see the real timeline, the people behind it, the respect we give to wool, and the decisions that make the shirt special. Trust isn’t built through marketing—it’s built through transparency.
A Shirt Worth Waiting For
When this shirt arrives at your door, it carries every hand-finished curve, every adjusted stitch, every deliberate choice of wool. It carries the honesty of the process you’ve witnessed. This isn’t fast fashion. This is responsible production, made with skill and intention. Thank you for supporting a product—and a philosophy—that chooses depth over speed. The final result will feel different, because the process behind it is different.

Inside Our Supply Chain
A Christmas Message from Flowool: Returning to What Truly Matters
Every December, the world speeds up—more gatherings, more noise, more lists to complete. Yet when the cold air settles and the year draws to a quiet close, something different happens. We slow down just enough to notice what feels real: warmth, movement, and a sense of belonging to something natural. This season offers an opportunity to reconnect with these essentials. And for us at Flowool, it is also a moment to reflect on why we create, how we create, and who we create for.
Choosing Nature in a Season of Excess
The holidays often encourage accumulation. More gifts, more packaging, more of everything. But nature teaches a different rhythm: clarity, intention, and balance. Our commitment to 100% Merino wool exists because natural fibers carry this rhythm within them. They breathe with you, warm you gently, and return to the earth without harm. In a season full of excess, choosing something natural becomes an act of grounding.
Movement as a Form of Gratitude
Movement is not only physical. It is emotional, mental, and relational. A quiet morning jog, a walk with friends, or simply the comfort of a warm base layer that lets your body breathe—these moments remind us to stay connected to ourselves. This is why “Where Nature Meets Movement” isn’t a slogan. It's an everyday philosophy. During the holidays, movement becomes a way of expressing gratitude—toward the body that carries us, the people who support us, and the world that sustains us.
A Community Built on Mindful Choices
Flowool has always grown differently—not through loud campaigns or fast trends, but through people who value authenticity, durability, and care. Every time someone chooses natural fibers over synthetics, long-lasting quality over disposable consumption, they influence the industry one step at a time. This community is built on small but powerful decisions. And for that, we are deeply grateful.
Looking Toward a New Year with Intention
The holidays are not an ending; they are a pause. A moment to ask ourselves: What do we want to carry into the new year? What can we leave behind? For us, the answer remains clear: Respect nature. Reduce waste. Create pieces that move with people—not just through a season, but through their lives.
A Warm Wish from Flowool
Wherever you are celebrating, we hope your days are filled with warmth, clarity, and the simple joy of choosing what feels true. Stay warm. Stay moving. Stay close to what matters.

Polyester 100% 20%
Merino 100% 80%
Fiber Structure Decoded
Merino wool fibers have a cross-section with a wavy, scaly structure and natural crimp, which allows the fibers to trap air, providing both excellent insulation and breathability. It can naturally absorb and wick away moisture, helping to regulate body temperature, while the fibers remain soft and durable.
Cotton fibers generally have a circular or oval cross-section with a smooth surface. Cotton has strong water absorption, but it dries slowly when wet, which can feel heavy and stuffy. Therefore, its performance in high-intensity exercise or rapid sweat-wicking scenarios is inferior to wool.
Polyester fibers usually have a circular or polygonal cross-section with a uniform, smooth surface. They are durable, lightweight, and quick-drying, but they do not absorb moisture, have poor breathability, and are prone to static. In terms of temperature regulation and sweat-wicking, they do not perform as well as natural fibers.
Overall, Merino wool clearly outperforms cotton and polyester in natural temperature regulation, moisture management, odor resistance, and wearing comfort, making it an excellent choice for sportswear and close-to-skin clothing.
