Introduction

Works well
on and off the trails

The Bamboo Shirt is a simple and tough trail shirt, perfect when you feel a little chilly on the trail.

Using bamboo fibers blended with polyester, the fabric is light and smooth. The shirt’s wind protection and natural moisture control performance will always keep you comfortable on the trails.

The ventilative wide fitting and open neck collar let the heat around the neck escape, offering comfort when it’s hot. Our proprietary design allows you to use the snap buttons for ventilation, or turn up the collar and button it up when it is cold. It effectively controls and flexibly adjusts the breathability and sensible temperature.

On and off the trails, you’ll probably be wearing it every day and never find a reason to hang it up.

Product Story

What’s so good about bamboo?

Akira Natsume, Yamatomichi Founder

We launched the development of our trail shirt series with the goal of creating something comfortable to wear both on and off the trail. We tested a number of materials during the development and were unable to narrow it down to just one, resulting in three products: the UL Shirt, Bamboo Shirt, and Merino Shirt.

Each has its own characteristics, good and bad. The UL Shirt and the Merino Shirt stand out among them, with the former being ultralight and having the strength of synthetic fibers, and the latter having the natural fiber’s powerful deodorizing and moisture control properties of 100% merino wool. Then, what is so good about the Bamboo Shirt?

The Bamboo Shirt is somewhere in between the UL Shirt and the Merino Shirt. The fabric, a blend of 50% bamboo and 50% polyester, features the toughness of synthetic fibers and the functionality of natural bamboo fibers which is similar to wool. But when written like this, it seems a bit half-baked compared to the other two products.
In fact, as we believe in creating the best products with cutting-edge functionality, we were not sure if we should commercialize this Bamboo Shirt, and even considered discontinuing its production.
Nevertheless, we continue to produce the Bamboo Shirt because we find it attractive. As mentioned above, the Bamboo Shirt has the toughness of synthetic fiber and the comfort of natural fiber, but its appeal is not limited to those functionalities; it is largely based on the atmosphere and feel of the garment.
It has a moist and comfortable texture, a subtle but elegant glossy smoothness, and a heather look of the bamboo/polyester blend.
It is wrinkle-proof and does not require sensitive handling. As you wear it, it develops a nice worn-in look.
Although not as cutting-edge as the UL Shirt or Merino Shirt, the Bamboo Shirt has a familiar and comfortable feel, which makes me always return to it. I even use the Bamboo Shirt as pajamas!
The Bamboo Shirt absorbs sweat better than the other two products. It can be worn like your favorite cotton T-shirt that endures everyday use; Wear it, wash it, repeatedly with no problem. (March 2022)

Form and Function

Excellent Humidity-control

Bamboo fibers absorb the discomforting heat and the accumulating humidity, while polyester has excellent fast-drying properties and durability. This 50/50 blend brings the best of both worlds for a tough and comfortable piece of fabric.

In a hot, humid environment, it is better to have fibers that absorb a lot of moisture to maintain a smooth texture. If the temperature is cold, it is better to use fibers that do not absorb a lot of moisture to keep comfortable and not feel too dry.

The chart below compares the moisture content inside the fibers in a hot, humid environment (a temperature of 30 degrees and 90% humidity) and an environment with optimal humidity (a temperature of 20 degrees and 65% humidity). We found that bamboo polyester maintains an optimal moisture content in both environments, and it has excellent humidity absorbency compared to a 100% polyester material.

High Deodorizing Properties

Bamboo polyester has been confirmed to have more than double the deodorizing properties that deodorized synthetic fibers have.

It neutralizes alkaline smells like ammonia and also helps to neutralize other odors because of its high ability to absorb humidity.

Natural UV Protection (UPF50+)

This bamboo polyester material has a natural UV protection of UPF50+, keeping you well protected against ultraviolet rays when on the move.

Trail Shirt

Woven fabric, which is often used as a material for shirts, is densely woven by warp and weft yarns. As a result, for the same weight and material, it is usually more windproof, dries faster, and is more durable than knitted fabrics, which are commonly used for base layers.

Furthermore, the UL Shirt adopts the basic “shirt” design, allowing for good ventilation by opening the front buttons. The essence of the shirt, the wind-protective fabric, and the good ventilation is namely the key feature of our hiking trail shirt, the UL Shirt.

Raised Collar

On a chilly morning or late evening, turn up your collar and secure it with the added button to keep out the chill. A turned-up collar also helps to prevent your neck from getting sunburned when the sun is up.

Trail Shirt Series Comparison

Material: Shadow Rip (100% Polyester) 56g/m² C0 DWR

Ultralight, wrinkle-proof, and extremely portable. Highly versatile and easy to use, both as activewear and as a change of clothes. Soft to the touch.

Merino Shirt

Keeps you comfortable with its high breathability and excellent temperature/humidity control. On the other hand, in midsummer, you may find wool a little too hot in the city or low mountains. Has a slightly firm texture similar to linen.

Bamboo Shirt
Bamboo Polyester (50% Rayon, 50% Polyester) 118g/m²

Bamboo polyester material has deodorant and moisture control functions similar to wool and the functionality of synthetic fiber such as polyester. It has a moist texture and superior sweat absorbency compared to the other two products. It develops a unique texture over time.

  • Breathability: Higher means better ventilation, while lower means it is more wind-protective.
  • UV protection: Ability to block the sunlight’s ultraviolet rays.

Material

Bamboo Polyester

Bamboo, a natural fiber, has excellent humidity absorbency, deodorizing properties, and block-out ultraviolet rays on par with wool. The weakness is that it is not that strong. Blending it with polyester, which has excellent durability and fast-drying properties, helped us achieve a material that can withstand rough handling when hiking and is comfortable to wear.

The bamboo fibers have a light, durable, and flexible feel. Traditionally bamboo has been widely used in Asia in a variety of products from food packaging to woven goods. Bamboo also grows extremely fast and can be harvested after only 2-3 years so is a very environmentally sound material.

The 50/50 bamboo/polyester blend has a unique cool, silky texture that doesn’t wrinkle easily even if stuffed somewhere in your backpack. The polyester also adds a nice glossy shine to the fabric making you stand out on the trail.
