Perfect Everyday Pullover
The 100％ Merino Pullover, made of our proprietary 100% Merino wool fabric (200-205g/m2), works equally well as either a base or mid-layer.
The simple design, like a normal sweater or sweatshirt, blends right in wherever you are, and the ribbed sleeves and hem keep your wrists and belly warm.
Our proprietary pure Merino fabric offers natural heat and humidity regulation as well as deodorization, making it so comfortable you’ll find it hard to ever take it off.
In 2021, we renewed our Merino fabric to be machine-washable and more durable for longer hikes and trips. It can be *tumble-dried at low temperature settings.
*Low temperature only. Please read “Care Instructions” for details.
The new fabric is 200-205g/㎡ in average weight. It is slightly thicker than the previous Merino series (170-180g/m²) but more thermally insulating.

Akira Natsume, Yamatomichi Founder
I love hoods. They guard against the cold wind, and often feel even warmer than a knit cap – I can’t begin to count the number of times I’ve been saved by my hood.
Yamatomichi has many hooded garments, but I realized that during winter if you’re wearing several layers, each with their own hood – whether it be a shell, thermals, base, or mid layers – you end up with a serious case of “hood congestion”.
You may think, “You can layer hoods, too!” but too many layers around the neck region can be a bit of a problem. Every time that happens, I end up wanting a basic long sleeve base/mid-layer, without the hood.
For this pullover, we developed a new fabric with ribbed cuffs and hems. We’ve always prided ourselves on developing lightweight materials, but maintaining reliable quality can be difficult if focusing too much on weight. Here we opted for a soft, slightly thick ribbed construction just perfect for a pullover.
Form and Function
Where the 100% Merino Stands
Though this product dries slower than general synthetic base layer T-shirts, it is less likely to cause hypothermia caused by the evaporation of sweat or other moisture. In other words, the new 100% Merino series focuses on moisture absorption rather than quick-drying, and on thermal insulation rather than cooling properties.
When the temperature changes drastically
Wool is good at maintaining a constant temperature inside the garment, keeping you dry and comfortable even in situations where temperatures can suddenly change.
When worn under an outer shell
Synthetic base layers with low moisture absorption can feel very humid and stuffy. On the other hand, our 100% Merino’s superior moisture absorption properties, will help to keep you dry and comfortable when worn under an outer shell.
When worn for long hours
Synthetic clothes often become smelly relatively early on, even if they are deodorant finished. Wools, on the other hand, naturally eliminate odor when the fabric dries even after being soaked in sweat. This powerful anti-odor performance allows you to keep moving day after day, relatively comfortably without smelling too bad.
When packing capacity is limited
Our Merino wool products can be worn in various situations for long hours without getting too smelly, minimizing the need for extra clothes in your backpack.
Naturally Odor Resistant
Wool base layers are chosen by many hikers for the material’s excellent odor neutralizing performance. Some say it’s almost odor-free even after a week of heavy hiking, but we’ll let you (and your friends) be the judge of that…
Great Moisture Control
Wool is great to help you keep warm and cool as it naturally controls the moisture level within the clothes, always keeping you comfortable throughout the year.
Even Warm When Wet
First, when wool absorbs moisture, the thermal phenomenon called “absorption heat” is generated. Secondly, its excellent insulation properties (low thermal conductivity) prevents the body heat from being lowered by evaporation. Also, the crimped fibers are bouncy and retain loft without crushing even when wet. In addition, wool can absorb more moisture in between the fibers, always keeping the skin dry and comfortable.
Tumble Dryable Pure Merino
Normally, Merino wool products cannot be tumble dried as the heat causes shrinkage and deformation of the fabric, but our proprietary 100% Merino wool can be tumble dried* at low temperatures (Upper limit of 60 Celsius).
This makes it better suited for long hikes and travels, as you can easily use dryers at laundromats and hotels.
The raglan sleeves enable easy movement of the shoulders and arms. The neckline is neatly trimmed by a neckband.
Ribbed Cuffs and Hem
The ribbed cuffs work as simple wrist warmers, helping to prevent heat loss and keep out the cold. By rolling up your sleeves you can quickly and effectively cool down. The thick ribbing helps retain warmth, which is important, as the abdomen, lower back, and buttocks are susceptible to the cold.
More Durable and Stable Quality
Our previous Merino series was produced by a combination of two strands of wool twisted together, known as “ply yarn”, featuring light and soft texture. However, this method could cause shrinkage after washing, possibly resulting in the partial bursting of the fabric.
So we analyzed the New Zealand Merino wool that we used in our old products to examine the optimal spinning and knitting methods; Our conclusion was to work with single yarn.
The fabric is pre-shrunk through tumble drying, which is a rare process for Merino clothes, making the fabric tight and compressed but bouncy. The process makes the fabric softer and more stable, allowing it to be tumble-dried at a low temperature.
Our proprietary fabric is produced in Bishu, the production area of wool garments in Japan, in cooperation with the spinning company, fabric factory, dyeing, and processing factory, and inspection organization. We continue our effort to innovate with new products and markets.

Why 100% Merino?
Wool is a natural material with various unique features such as temperature/moisture control, thermal insulation, and is naturally odor-resistant. All developed by sheep to survive the harsh environment over time.
Merino wool comes from merino sheep and compared to other kinds of wool, merino’s fiber is finer, softer, and less scratchy, and hence even suitable for making underwear and baselayers.
All wool, including merino wool, is cool in summer and warm in winter. It is warm even when it’s wet, and practically odor-free even after many hours of wear.
While many other manufacturers add synthetic fibers to strengthen their Merino fabrics, we wanted to stick with 100% Merino to maximize the natural benefits of pure merino wool. Our merino will keep you dry even when it’s hot and humid and comfortable no matter the climate.

All wools, including merino wool, are cool in summer and warm in winter. It is warm even when it’s wet, and practically odor-free even after many hours of wear.
The wool’s fiber is composed of amino acid-based protein, just like human hair and skin. The surface is called the “scale”, which is similar to a fish scale, and the inner part is the “cortex”.
The cortex is composed of ortho-cortex and para-cortex, each with different moisture absorption performance. Because each of them differs in property, the combination of ortho and para cortexes makes the fiber “crimped”.
This crimped structure produces the wool’s unique features such as moisture/temperature control property and thermal insulation performance, avoiding the coldness caused by the sweat.
Disadvantages of Wool
Wool or merino wool has various features and functions, but it is not flawless.
- Heavy when wet
when it’s wet and takes longer to dry compared with most synthetic materials. Fast-drying synthetic materials, however, can be cold when wet because it deprives body heat excessively quickly as it dries due to evaporation. Wool dries slower than synthetic materials but quicker than cotton with a similar thickness.
- Liked by insects
Soft, natural fibers such as wool, cashmere, and silk are prone to damage by insects.
- Tears easily
The relatively short fibers of wool mean that wool fabrics are easier damaged than synthetic and cotton fibers. However, small holes can easily be fixed with a bit of pure wool and a needle.
- Shrinks easily
Wool generally shrinks easily, even when shrink-proofed. To reduce shrinkage, after the wash, please spread the shirt well to return to the original shape and gently iron it.
When knitted wool fabrics are washed, the material is likely to distort diagonally because the yarned fibers absorb water, swell, and tend to untwist. Consequently, the shape of the shirt may distort slightly with washing.
- Distinctive smell
The wool comes from sheep and you may experience a distinctive animal-like smell coming from your t-shirt when damp. This smell disappears after the fabric dries.

– Due to the nature of the material, there may be some individual differences in the shrinkage. The extent of the shrinkage may vary depending on the type of washing machine or the machine settings.
– Using a dryer with a low-temperature setting may cause the garment to shrink more than when dried naturally. It will be restored after it is washed again and flat-dried.
– To reduce shrinkage after the wash, gently spread the shirt and iron it.
Hydrophilic 100% Merino
While normal merino wool fabrics are water-repellent finished at the manufacturing stage, our 100% Merino has a hydrophilic finish for better wicking performance.
However, the yarn is waxed to improve knitting efficiency during the mass-production process, which may not be fully removed by washing in the final processing stage, and the remaining wax may repel water, hindering the fabric’s absorption.
For better wicking of the fabric, please wash two or three times to remove the residual wax.
When the 100% Merino Light item in Blue, Mustard, or Navy is in contact with a white or light-colored shirt wet from rain or sweat, color may transfer and stain the shirt.
This product is tumble-dried with a low-temperature setting (60 degrees Celcius or lower). Please note that the dryer should be used only when it is necessary to prolong the lifetime of the garment.
- This product is made of highly odor-resistant merino wool, which usually does not require a frequent wash.

A natural fiber, merino wool has wonderful properties such as excellent temperature and humidity control and deodorant performances, but it also has a weakness; yarns are likely to break and develop holes due to abusive use and moth eating.
For inquiries on repairing holes or products damaged over time, please feel free to contact us from the “Repair” section of the SUPPORT page.
Holes in merino wool cut-and-sewn products caused by thread breakage or moth bites can be repaired by felting, a technique to patch the hole with the raw wool using a special needle. You can repair by yourself, and Yamatomichi also offers felting repair services using raw wool of the same color as the product.
