This light (145-155g/m2) regular-fit T-shirt is always the right choice as your go-to base layer.

Our 100% pure Merino wool will make your hiking more comfortable by keeping unwanted odors to a minimum.

Not only does it help regulate both temperatures and humidity when you hike, it can also be tumble-dried (maximum 60°C), making it a great piece for long-distance adventures.

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 Light 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. For details, please visit HERE (Currently available in Japanese only).

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.

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…

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.

When wool absorbs moisture, the thermal phenomenon called “absorption heat” is generated. Its excellent insulation properties (low thermal conductivity) prevent body heat from being lowered. In addition, wool is great at absorbing moisture, always keeping the skin dry and comfortable.

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.

We have focused on using 100% merino wool without synthetic fibers. Our proprietary fabric is produced in Bishu, a historical production area for wool clothing in Japan. In cooperation with a spinning company, fabric factory, dyeing company, processing factory, and inspection organization, we continue our effort to innovate new products and markets.

Compatible with low-temperature dryers
The 100% Merino Light series undergoes a shrinking by deliberately being put through a dryer. By going through this labor-intensive process, we have achieved compatibility with low-temperature drying machines, a feature not found in other Merino wool products. This heat treatment creates a unique wavy texture to the fabric.

Compact Spinning
Our 100% Merino wool uses this “compact spinning” yarn. A method not often done with wool, fibers are condensed before twisted into yarn, resulting in a more smoother, stable and stronger yarn.

100% Merino Wool

Wool is a natural material with various unique features such as temperature/moisture control, thermal insulation, and is naturally odor-resistant. All are developed by sheep to survive the harsh environment over time.

Merino wool comes from merino sheep and compared to other kinds of wool, merino 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.

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 than 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.

• Easily damaged
  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 washing, stretch the shirt to its original shape and gently iron it before drying.

• Distortion
  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 usually disappears after the fabric dries.

The fabric will stretch approximately 1 cm vertically when hung to dry from from the listed values.

– The above values show the measurement when the item is brand-new and unwashed.
– Due to the characteristics of elastic knit materials, the sizing may vary 1-2cm.
– Due to the difference in the shrinkage tendency, there may be some individual differences in the measurements of the product.
– Tumble-drying at low temperatures may cause more shrinkage than when dried by natural drying. The shrunk item will be restored by washing and line-drying again.
– Iron with steam if shrunk after the wash and drying. Gently stretch the fabric while ironing for the best results.

When the color Charcoal Marl or Navy is in contact with a white or light-colored shirt in a wet state from rain or sweat, color may transfer and stain the shirt.

When using a tumble-dryer, use a low-temperature setting (up to 60°C). However, since fabric pilling is more likely to occur, please avoid frequent dryer use.
Wrinkles can form if the fabric is bunched up during the drying process., Do not use a laundry net and dry items individually or with ample space. Promptly remove items from the dryer after drying.

Tumble-drying may cause shrinkage of about 1-2cm, but can be restored with frequent washing. washed again and line-dried.

• This product is made of highly odor-resistant merino wool, which usually does not require a frequent wash.
• The fabric uses shrink-proof pure merino wool. It is machine-washable by “Gentle Course” or “Hand Wash Course” with gentle water flow.
• When you store the item, use mothballs and/or vacuum storage bags to keep out insects.
• Merino’s fibers are short, and fuzz and pilling may appear, which can be removed by several washes.
