A Classic 100% Merino Full Zip Hoody
If you think this is just another regular hoody, please read on.
Our proprietary 100% merino wool used for this and the Half Zip hoody is as durable as a merino/synthetic blend and has just the right thickness (170-180g/m2) to prevent overheating during outdoor activities. The front double zipper also allows for maximum ventilation control.
The fabric possesses all the natural temperature, moisture, and odor regulating properties of 100% merino wool, allowing for it to remain comfortable even in situations where it has to be worn for several days in a row.

Akira Natsume, Yamatomichi Founder
The Yamatomichi Merino Hoody was originally designed to retain core heat, so we never really considered adding a full zip.
After giving it some more thought, however, we realized that because a full zip hoody would just have two pockets instead of the large kangaroo pocket, the insulation properties might not change significantly, so we decided to give it a test.
After wearing it for a full season, we were impressed with how easily the full zip hoody could be put on and taken off. While the Merino Hoody is suited for continuous outdoor wear during the colder months, the Merino Full Zip Hoody can be worn in slightly warmer weather either outdoors or in town. It is perfect for activities that demand breathable clothing or frequent removal.
Form and Function
Form Follows Function
What we ultimately set out to make was a super functional 100% merino wool base/middle layer.
After much testing to find the most functional design of an ideal base/middle layer, we concluded that the classic sweat hoody design would be perfect.
When feeling a little cold, just put on the warm hood for quick and comfortable added warmth. In extremely cold and snowy mountains, balaclavas that cover your nose will keep you warmer, but except for these rare occasions, generally, we think balaclavas are a bit too much. Our hoody’s zipper ends at the chin and is adjustable with the 2mm stretch cord and a simple stopper, allowing for easy adjustment on the go.
The front two-way zipper accelerates ventilation performance.
Ribbed Cuffs and Hem
In order to keep your body temperature stable, your neck, wrists, and ankles should be kept warm, allowing for your bloodstream to flow smoothly. The ribbed cuffs work as simple wrist warmers. The stomach and waist are also sensitive to cold, so the material of the hem is ribbed and thickened.
The sleeves are easy to roll up if needed.
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.
A stronger Merino
We love all the functionality of merino wool but also wanted to make a strong and durable product. By using a combination of two strands of wool twisted together, known as “ply-yarning”, we managed to develop a 100% merino fabric that is as strong and durable as the more common synthetic/wool blended fabrics.
Made in Japan Merino
We developed this unique fabric with specialized textile professionals in Bishu (in Aichi and adjacent Gifu prefectures), the largest production area of wool garments in Japan. Our merino wool products are spun, yarned, dyed, and knitted in Japan.
It is soft, comfortable, and highly sweat-absorbing pure Merino.

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 the 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
As explained above, wool or merino wool has various features and functions, but it is not flawless.
Easily absorbs moisture and becomes heavy
Wool can get quite heavy as it is great at absorbing moisture. This also means that wool takes longer to dry and synthetic fibers, but compared to cotton, it actually dries faster.
Liked by insects
Soft, natural fibers such as wool, cashmere, and silk are prone to damage by insects.
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.
Wool generally shrinks easily, even when f 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.
The wool comes from sheep and you may experience a distinctive animal-like smell coming from your t-shirt when damp. This smell usually disappears after the fabric dries.

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.
For more instructions on washing, drying and storage at home, please read on the “Read More” section below.
【How to Wash】
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.
- Wool fibers are slightly acidic, so avoid washing with alkaline detergent as it may damage the texture. Use a neutral detergent.
- 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.
- 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 wash at high temperature as it may cause shrinkage.
- 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.
- Do not tumble-dry, as the texture of the fabric may be hardened.
- 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.
- Washing may cause slight deformation or distortion due to the nature of the fabric.
【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.
- Steam must be low temperature (80℃-120℃).
- Do not apply the iron surface directly to the fabric, but apply only steam to the wrinkled area. To prevent the fabric from shrinking due to the heat, gently stretch the fabric as you steam.
- After steaming 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.
【Straightening out shrinkage and 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.
- Dry well before storing. If there is any moisture left, it will be prone to insect damage.
- Steam from an iron can effectively kill insects by heat. Use a low 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. In this case, an insect repellent specially designed for vacuum bags is recommended. Air left in the bag will allow insects to survive.
- 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.
For more details of felting and how we repair the merino items, visit Yamatomichi JOURNALS 『山と道修理部通信#1 メリノウールの穴を補修する』(Japanese only).
