Introduction

Wool pants for a pleasant winter

Hiking or at home, this pair will make your winter comfortable.

We selected super soft and flexible Italian merino wool for optimal comfort and warmth. Ripstop nylon thread has been interwoven at the back of the fabric for enhanced durability. Our trusted 5-Pocket system offers maximum usability.

Merino 5-Pocket Pants are tough and flexible woolen pants for wherever you go during the cold months.

Product story

Always my favorite

Akira Natsume, Yamatomichi Founder

I usually wear our 5-Pocket Pants even during winter, but I have to admit that they are not warm enough when it’s really cold and I sometimes wear an additional pair of insulation tights to keep warm. I wanted to make a pair of pants that could keep me warm even in the middle of winter without the need for tights. If they look good at home too, that would be even better.

In the first year of development, we made several prototypes using various types of wool fabrics. The pants were really comfortable during long hikes thanks to their natural moisture absorption properties, but I occasionally got itchy because of the wool. Another concern was that the surface of the textile got fuzzy and rough after just one season of use.

In the second year, we tested several blended materials made of wool and synthetic fiber. They were comfortable, relatively inexpensive, strong, and durable. Unfortunately, as the percentage of wool declined, the warmth and comfort of the wool unavoidably diminished.

I kept insisting on a pair of pants made of 100% wool with our unique 5-pocket system but was struggling to find the right material that would fulfill all our requirements.

Finally, I found the ideal merino fabric at a traditional textile maker in Italy. It is yarned and produced at the maker’s own factory using merino sheep’s wool carefully brought up on their own farm in New Zealand. It was super comfortable and had an excellent texture.

In the third year of development, I tested several prototypes made from their fabrics and wore them from autumn to spring. The merino textile was really comfortable, not super warm, but just right.

After one season of use, I did find minor pilling on the pants if I took a close look, but it appeared just fine with no noticeable fuzz on the surface, and the texture faded in a good way over time.

It’s difficult to pinpoint exactly what’s so good about our Merino 5-Pocket Pants. They are not as technologically advanced as the Winter Hike Pants or super stylish either.

For me, our Merino 5-Pocket pants are for daily use. They are not as light and smooth as synthetic fleece, but flexible and soft. When the fabric gently touches my skin, I just feel happy wearing them.

For technical purposes, high altitude winter hikes, the Winter Hike Pants are still my first choice. But when I travel and visit both towns and low mountains, the Merino 5-Pocket Pants are definitely my favorite. This pair of pants made from natural wool keeps me comfortable day and night, wherever I go.

Form and function

Pockets for smartphone and maps

Yamatomichi 5-Pocket design can neatly store your map, snack, wallet, and other items you need during hiking, without interfering with your leg movement.

Especially, our smartphone pocket at the side is so well-positioned that it fits your phone while keeping it securely in place without bouncing around when running. The map pocket is large enough to store the water bottle.

1st pocket
Large enough for comfortable keeping your hands in your pockets while hiking.

2nd pocket
The 2nd pocket is perfect for your smartphone. The perfectly-allocated pocket just behind the hipbone secures a smooth leg lift, preventing your phone from bouncing around, and keeps your phone safe and intact when sitting.

3rd pocket
The 3rd pocket is positioned high for wallets, etc. The long zipper tab allows for easy opening/closure of the pocket.

Key Loop
You can attach keys or a small carabiner to the long key loop. It’s also handy when you hang the pants to dry.

4th pocket
The lower part of the pocket liner is made of polyester mesh for drainage should the pants get wet.

5th pocket
The 5th pocket is made to fit the size of the normal hiking map. It is also perfect for a large-screen smartphone, compact digital camera, and even a water bottle.

Gusseted crotch
The crotch is widely gusseted to allow for dynamic leg movement.

Details

Featuring a fitted waist and hip area, the pants offer a smooth, streamlined look throughout.

The waist has a built-in nylon tape belt with buckle closure.

Naturally odor resistant

Merino wool’s deodorant mechanism is still a mystery. 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…

One theory has it that wool absorbs a large amount of odor-causing elements, and consequently, the odor is minimized to the level that cannot be detected by the sense of smell.

The figure above shows how much the ammonia component—one of the main causes of odor—decreased after 24 hours. A higher value indicates a greater reduction in ammonia levels, meaning that less odor remains.

Great moisture control

Often called “nature’s air conditioner,” Merino wool naturally regulates temperature and humidity, keeping you comfortable in both heat and cold.

Its crimped fibers create tiny air pockets that enhance breathability and insulation, while the cortex absorbs and releases moisture according to ambient humidity.

These features allow Merino wool to retain warmth like down yet remain cool and dry, offering superior comfort compared to cotton or synthetics.

Warm when wet

When fibers absorb moisture, they release a thermal effect known as “absorption heat.”
Wool generates about twenty times more absorption heat than polyester and 2.5 times more than cotton.

Its low thermal conductivity helps retain body warmth, while the elastic structure of the yarn prevents the loft from collapsing when damp, maintaining excellent insulation.
Moreover, wool’s ability to draw moisture into the core of each fiber wicks sweat away from the skin, keeping you warm and comfortable during movement.

As a result, 100% Merino wool keeps you warm and protected even in severe conditions that soak you to the skin.

Material

Italian made NZ merino

The fabric is merino wool manufactured by a well-established Italian maker, which runs the thorough production process including sheep farming, yarn making, and fabric making in New Zealand.

The back of the fabric is reinforced by the rip-stop Cordura nylon, achieving both the softness of the merino wool and the toughness required for hiking pants.

Why merino?

Although Merino wool naturally excels at regulating temperature and moisture and resists odor, it can be prone to distortion and wear. To reinforce these weaknesses without compromising performance, the Merino 5-Pocket Pants use a 97% Merino wool fabric, backed with a minimal layer of Cordura® nylon yarn for added durability.

The chart above compares the moisture content of three fabrics under hot and humid conditions (top: 30°C, 90% humidity) and a more comfortable environment (bottom: 20°C, 65% humidity).

In humid conditions, fibers with high moisture absorption help keep you dry and comfortable. In contrast, under dry conditions, comfort improves when a fabric retains moderate moisture rather than absorbing too much from the air. The difference in moisture content between the two environments indicates a fabric’s moisture control performance—the larger the difference, the better its comfort balance.

As shown, 100% Merino wool exhibits a 6.8% difference, demonstrating its outstanding ability to regulate moisture—keeping you dry in humid heat and comfortably hydrated in dryness.
This is why Merino wool is often called “nature’s air conditioner.”

Merino wool

Wool is a natural material with various unique features such as temperature/moisture control, thermal insulation, and anti-odor performance; all of them developed by sheep to survive the harsh environment over time.

Merino wool, sourced from Merino sheep, has finer, softer, and smoother fibers than ordinary wool, making it comfortable enough to wear directly against the skin, even as underwear.

All wools, especially merino, keep you cool in summer and warm in winter. It retains warmth even when wet and remains virtually odor free even after prolonged wear.

Wool’s structure

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.

  • 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./li>
  • 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.

Instructions

Care instructions

Merino wool has excellent deodorant properties, it does not need to be washed frequently. However, it does have some disadvantages, such as a tendency to develop holes due to insect bites, so it should be washed and stored properly.
