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. Also, our proprietary 100% Merino can be tumble dried at a low temperature, making it easy to wash and dry on the go.
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.
Consequently, 100% Merino wool keeps you warm during the action, even in severe weather that makes you wet to the skin.
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, the fabric may shrink about 1.5cm vertically and 1cm horizontally after a few washes, so the size of the product is determined considering the shrinkage of the fabric after washing.
*The above sizes are the measurements of the garments at an unwashed state. They are these sizes when brand new.
*Due to the elasticity of the knit material, there may be some individual differences in the size of the product.
*Due to the nature of the material, there may be some individual differences in the shrinkage. How the fabric shrinks may vary depending on the type of washing machine or course settings.
*Using a dryer with a low temperature setting may cause the garment to shrink more than when dried naturally, but it will return to its original shape as it is worn.
While most Merino wool fabrics have a water-repellent finish when they are manufactured, our 100% Merino has a hydrophilic finish to quickly absorb sweat.
For our latest 100% Merino fabric, the yarn is waxed for better knitting efficiency in the manufacturing process. This wax was supposed to be washed away before the finalization, but it partially remains in some product colors, which may hinder the water absorption performance of hydrophilic processing. As a result, the fabric may repel water if the product is new and unwashed.
Please wash the product a few times at home to remove residual wax so that the product’s hydrophilic performance is restored and the fabric absorbs water properly.
Wicking Performance by Product Color
- Gray Marl: Wicks quickly before the first wash.
- Blue、Pale Yellow、Blue Gray: Takes 30 to 60 seconds for the fabric to absorb water if unwashed. After washing it a few times, it will become fast-wicking.
- Black、Navy: Repels water if unwashed. After washing them two or three times, they will become fast-wicking.
*Depending on the type of washing machine and the amount of detergent used, the number of washes required to restore the water absorbency may vary.
*Use neutral detergent only and observe the specified usage amount.
When rubbed against a white or light-colored shirt during rain or when wet from sweating, the colors may transfer and stain the shirt.
Merino wool has excellent deodorizing properties, but it does have some disadvantages, such as being prone to moth holes and shrinkage. Therefore, It should be washed and stored properly, though not frequently. Yamatomichi 100% Merino and 100% Merino Light products can be tumble-dried at a low-temperature setting (60℃ or lower).
For more instructions on washing, drying and storage at home, please read on the “Read More” section below.
It is machine-washable, but please be careful with water temperature and machine settings as it may cause shrinkage. Because merino wool is a natural fiber, its fibers are short, and fuzz and pilling may appear, but after several washes, they will become less noticeable.
- Use a neutral detergent. Wool fibers are chiefly composed of animal proteins that are vulnerable to alkalinity, so avoid washing with alkaline detergent as it may damage the texture.
- Close the zippers, if any, to avoid the damage caused by the contact with metal parts.
- To avoid damage caused by contact with other laundry, or deformation caused by tangling, please wash it separately or use a laundry net.
- Please wash it separately from white or light-colored clothing to avoid a color transfer.
- Set your washing machine to “Gentle Course” or “Hand Wash Course” with gentle water flow. This will shorten the stressful process of wringing and dewatering, and minimize the risk of shrinkage and deformation.
- Washing with lukewarm water (about 30℃) will help remove dirt even with gentle water flow.
- Do not use fabric softener as it may coat the fibers and hinder the natural properties of wool.
- Do not bleach as it may cause color fading.
- Smooth out the wrinkles, adjust the shape, and dry flat in the shade. Line dry is not recommended as the wet fabric may be stretched by its own weight.
- Washing may cause slight deformation or distortion due to the nature of the fabric.
Precautions when using the dryer
The dryer can be used at a low-temperature setting (60℃ or lower). Please note, however, that repeated use of the dryer can damage the product. it is recommended to use the dryer only when necessary to prolong the product life.
How to Remove Wrinkles
Knit fabrics are less likely to wrinkle than woven fabrics, but if the wrinkles are noticeable, please iron the fabric. There is, however, a risk of fabric shrinkage if the fabric is continuously exposed to iron steam at an excessively high temperature. Please follow the precautions below when ironing.
- Use a steam iron.
- Always use the iron at a medium temperature (around 140°C to 160°C) setting or lower.
- Avoid applying pressure, and let the steam blow over the fabric while slightly lifting the iron. Gently stretch the fabric while ironing for the best results.
- After applying steam for a few seconds, gently smooth out the wrinkles with your hands.
- If the wrinkles are still noticeable, apply a thin cloth and softly iron the fabric.
- After ironing, dry completely.
Keep in Shape
Shrunk or deformed clothes can be restored by ironing them. However, there is a risk of fabric damage and shrinkage if the fabric is continuously exposed to high temperatures.
- Do not strongly press the iron. Lightly iron with steam.
- Always use the iron at a medium temperature (around 140°C to 160°C) setting or lower.
- Avoid applying pressure, and let the steam blow over the fabric while slightly lifting the iron. If there is any shrinkage, apply steam while stretching out the fabric.
- After blowing steam for a few seconds, stretch the fabric little by little while it is still moist by the steam to touch up the shape.
- After the shape adjustments, leave it for a while without moving it. Dry it completely afterward.
How to Avoid Insect Damage
Merino wool, an animal-derived fiber, has the disadvantage of being easily eaten by insects because of the protein contained in the fiber. However, the risk of insect damage can be reduced by proper care.
- If there is any dirt left, it can attract insects, so be sure to wash thoroughly before storing.
- Steam from an iron can effectively kill insects by heat. Use a medium temperature setting when ironing, and after steam, dry it completely before storing it.
- Keep well-ventilated. Avoid humid environments.
- Vacuum storage bags are also effective in preventing insect damage. Air left in the bag will allow insects to survive. Therefore make sure to completely seal the bag before storing it. Please note that vacuum sealing may cause wrinkles.
- if you choose to use moth balls, please follow the instructions found on the detergent.

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.
