Product Story

Tough and Easy to Use

Akira Natsume, Yamatomichi Founder

Our first backpack, ONE, was designed to be ultralight, yet internally framed, capable of distributing the load on the waist.

Some years after the release of ONE I began to explore making a comfortable and easy-to-use backpack, that would be a bit more robust, and hence more reliable, but still comfortable and easy to use.

My hiking style also changed over the years, and ONE simply became too large in many cases, so I was exploring a downsized version of ONE, that was meant to be released as “TWO,” but I wasn’t fully satisfied with the prototype so abandoned this idea and focused on making a larger version of the MINI that eventually became the Yamatomichi THREE.

THREE is not, however, merely an enlarged version of MINI. I wanted to make a pack as quick to use and comfortable as MINI, but being capable of distributing a larger load on the waist.

Initially, the prototype’s hip belt was padded, which turned out to be restricting the free movement of the waist. After a thru-hiking for product testing in the Northern Alps, I concluded that regular webbing would work just fine to distribute the load on the waist if the pack’s structure was properly designed. Hence, I removed the padding from the hip belt but increased the width of the webbing from 25mm to 38mm for added comfort.

As a result, although frameless, THREE comfortably allows the carrying of a decent amount of gear distributing the load around the upper torso and upper part of the waist. A conventional pack’s firm and the padded hip belt does sit on the waist securely, but it tends to limit the freedom of waist movement. The low-profile webbing hip belt used on the THREE keeps the waist free when on the move.

I tested various closure methods and ended up with a simple water repellent zipper. Although zippers might break, I focused more on usability and adopted a zipper closure that allows quick access to the items than a draw-string. I also like the fact that it can hold the gear up to the maximum capacity, without redundant fabric.

Consequently, the THREE came out as a very unique backpack, different from both the ONE and the MINI. THREE is perfect for ultralight multi-day hiking. I also recommend it for winter hiking with lots of snow gear.

Form and Function

Freedom on the Move

The THREE is designed to allocate the load on the back and waist using only a simple webbing hip belt, which keeps the load closer to the upper part of the waist.

It’s not designed to carry the main load on the waist like more conventional backpacks with heavy hip belts, but its free-waist design liberates the lower body and allows for a comfortable hike. Although THREE is frameless, our test shows that it can comfortably carry approximately 10 kilograms of weight.

Three Types of Large Front Pockets

The large front pockets are available in Standard, Mesh, and Zip, each serving a different purpose. The pocket is large enough to fit a climbing helmet, or you can store a tent, groundsheet, rainwear, etc. with plenty of room to spare.

The front pocket is placed in the middle of the body so that the load can ride on your hip bones should you overload it.

Easy Access

The zippered main compartment opens and closes much easier and faster than a drawstring pocket, making access to your belongings a breeze.

It also allows you to fill your bags to the maximum capacity without having to squeeze them to close like a drawstring or roll-top compartment.

Details

We’ve paid a lot of attention to the details of the THREE to make it as easy and comfortable to use as possible.

The bottom attachment loops, bungee cords in front of the front pocket, and side straps hold snowshoes and other gear making the THREE perfect for winter hiking with a lot of extra gear.

Material

Highly Durable and Water Repellent X-Pac VX21

Material: 210 denier nylon, black polyester X-Ply, polyester film, 50 denier polyester (Durable Water Repellent)
Weight: 203g/m

X-Pac VX21, which we use for the bottom parts of the ONE and MINI, is a durable and water-resistant multi-layer fabric. It is comprised of a wear-resistant 210 denier nylon on the surface, a water-resistant PET film in the middle, and a 50 denier polyester taffeta and diamond-patterned black polyester X-Ply material at the bottom, combined with the hydrostatic water-resistant structural technology.

*Dull Gold, Spruce, and Towney Port are our bespoke version of Pertex fabric.

In-house Test Result (Erros may occur depending on the production lot of the fabric)
Tensile strength (JIS L 1096 A method): Vertical 123kg, Horizontal 119kg
Tear strength (JIS L 1096 A method): Vertical 12.2kg, Horizontal 9.9kg

We offer two sizes of the MINI. In general, we recommend the larger L size if you are over 175cm tall, but as all people are different we recommend you try out the two different sizes before you buy if at all possible.

  • The length of the shoulder strap is the straight line from the base of the strap to the end of the core material.
  • Please refer to the ONE Custom Order page for more information on how we measure the length of the back of our backpacks.
  • If correctly sized, the backpack should sit on the upper hip, between the sacrum and spine.

Please Note
