These pants were born from thoroughly considering every feature a hiker truly needs.

The result, a unique pattern that allows full freedom of movement, letting you hike Japan’s steep mountains in comfort. The fabric is highly durable for rough use, dries quickly when wet, and features pockets that neatly store essentials like maps and trail snacks.

Especially noteworthy is the smartphone pocket — so well-fitted, you might forget you’re even carrying one. Easy to wear on the trail, in town, or while traveling — these are the original Yamatomichi Pants.

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.

Though the material is non-stretchable, the outstanding ease of movement is achieved by our proprietary pattern and the three-dimensional sewing. The pants are stress-free and comfortable even when you have to raise your leg high on a steep trail.

In the pouring rain, even water-repellent finished clothes will unavoidably get wet. Also, even the highest-spec rainwear gets soaked from the moisture caused by sweat during intense exercise. Hence, what we prioritize is how fast the fabric can dry after getting wet, rather than making a lot of effort to keep them completely dry.

Generally, the thinner the fabric, the faster it dries. It is true that fast-drying property matters for hiking, but at the same time, a certain level of durability and strength are required.

The cotton-like Taslan with 120g/㎡, the material used for the Pants, is lightweight, fast-dry, and durable.

Check out the chart below to see just how quickly the 5-Pocket Pants outperform other fabrics in drying time.

After a 15-minute spin cycle, we measured the remaining moisture content across different materials. The results speak for themselves:

With only 1% moisture remaining, the 5-Pocket Pants are nearly dry straight out of the machine—far ahead of typical cotton or synthetic base layers.

We offer a range of bottoms designed for spring, summer, and autumn: the original 5-Pocket Pants/Shorts, the ultralight and breathable Light 5-Pocket Pants/Short Shorts, and the DW 5-Pocket Pants/Shorts, which land somewhere in between. Each has its own strengths depending on the season, activity, or personal preference, but they all follow the same overall design. You can find more details from the article below.

Taslan nylon is made from air-textured yarns—filament fibers that are spun using compressed air to create a uniquely soft and matte finish.

Unlike typical nylon fabrics that tend to be shiny, Taslan nylon offers a more natural look and feel. It’s a high-density material that strikes the perfect balance between durability and lightness.

Thanks to its fast-drying properties and subtly textured surface, it stays comfortable against your skin—even in sweaty or wet conditions—without clinging.
