Light Hiking Pants
The Light 5-Pocket Pants are a cooler and lighter version of our 5-Pocket Pants. The elastic Pertex Equilibrium fabric is super comfortable even when hiking on hot summer days. As with all our 5-Pocket Pants, the five pockets are uniquely positioned to hold your smartphone and maps, while ensuring maximum flexible leg movement.
The paper-thin fabric makes the Light 5-Pocket Pants ultralight and comfortable, but they are weaker and less durable than our other pants. Please handle them with care.
The design has been revised since 2022 to be slightly roomier for ease of movement than the 2021 version or older. The silhouette of the latest version is closer to that of DW 5-Pocket Pants.

Akira Natsume, Yamatomichi Founder
I was using our 5-Pocket Shorts during the summer and our 5-Pocket Pants when it got colder. That is, unless there was a particular reason to wear long pants. I never really considered wearing the long 5-Pocket Pants during summer. Surely, shorts are best on a hot summer day, right?
That said, some of our customers preferred to wear their 5-Pocket Shorts even in the summer. I also noticed that some of them were wearing tights under our 5-Pocket Pants.
After all, shorts-only in the summer didn’t seem like the mainstream style here in Japan. So I decided to create a sweat-free and ultralight pair of long pants that are as comfortable to wear as our shorts.
The original 5-Pocket Pants are made of non-elastic and non-polyurethane Taslan nylon. Although polyurethane is frequently used in many materials for its stretch property, I didn’t really like it because it tended to be slow-drying with inferior durability and weak wind protection. Non-polyurethane Taslan nylon, on the other hand, did not stretch but it was quick-drying, windproof, and durable. After many tests, I discovered the ideal, comfortable shape of the 5-Pocket Pants made of Taslan nylon. But when I discovered the Pertex Equilibrium, this turned out to be the ideal non-polyurethane fabric for its slight elastic performance.
It might not be as durable as 100% Taslan nylon, but the Pertex Equilibrium’s smooth texture and lightness are its great advantages.
Considering the stretch of the material, the thighs of the pants are slightly slimmer compared to our regular 5-Pocket Pants. Of course, these light pants also use the 5-Pocket system, so you can comfortably keep your hands in the side pockets and stow your map or smartphone in other pockets as usual.
Our Light 5-Pocket Pants are only half the weight of the original 5-Pocket Pants. Because of the flexible fabric, you can even do yoga in these pants, without overheating even on a hot summer day.
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.
Ultra Light. Ultra Flexible.
By using the Pertex Equilibrium fabric, we managed to create a pair of pants weighing only half of our regular 5-Pocket Pants. The Equilibrium is also slightly elastic allowing for great flexibility when hiking.
The twist-processing of the fibers and optimum weaving design create a slight two-way stretch even without the polyurethane material, which is elastic but easy to deteriorate with age.
The Pertex Equilibrium comprises 20 denier threads on the surface and 40 denier weft threads on the backside for more flexibility and lightness; a combination of the fibers with different deniers creates a unique irregular texture to keep your skin dry.
As the fabric is super thin it dries in no time! The elastic waistband uses mesh material for quicker drying and better comfort when it gets wet from sweat or rain.
The chart below shows the moisture content in the fabric after 15 minutes of spin-dry. It compares our Light 5-Pocket Pants/Shorts with the base layers of major manufacturers, as well as a standard cotton shirt.
The lower the moisture content, the faster it dries. The Light 5-Pocket Pants/Short show that it is only 0.3% of water content after 15 minutes of spin-dry, which means it is almost completely dry.
Yamatomichi offers three types of bottoms for the three seasons of spring, summer, and autumn: the Light 5-Pocket Pants/Shorts, which are super light and offer exceptional breathability; the standard 5-Pocket Pants/Shorts, the origin of the series; and the DW 5-Pocket Pants/Shorts, which are somewhat in the middle between the two.
Please visit the below page for details and comparisons of all our 5-Pocket Pants and Shorts.
Each has its own advantages and disadvantages depending on the situation, season, and application, but all of the designs are similar. Please visit the following link for details.
Pertex Equilibrium uses a unique double weave construction for lightweight and comfort. Our Light 5-Pocket Pants/Shorts use a lightweight Pertex Equilibrium, weighing only 55 grams per square meter, achieving a significant weight saving, which is about half the weight of our conventional Pants and Shorts.
Though the material is paper-thin, it comprises 20 denier threads on the surface and 40 denier weft threads on the backside, making it more robust than most other textiles with a similar thickness. The combination of the fibers with different deniers creates a unique irregular texture, to keep your skin dry.
The twist-processing of the fibers and optimum weaving design create a slight two-way stretch even though it is a non-polyurethane material.
The material is a blended fabric made of nylon and polyester, creating a unique heather pattern on the surface.

*Slight size differences may occur due to fabric shrinkage and sewing variations.
The Pertex Equilibrium, the fabric used in the Light 5-Pocket Shorts/Pants, is very thin and lightweight.
The rip-stop construction provides some strength, but sharp objects such as rocks and branches can scratch and possibly tear the fabric. Please be careful when you walk through rocky ridges or sit down to rest on a rock.
The Light 5-Pocket series uses a special double-weave fabric, with thick yarns on the backside. When the thick yarns, made up of bundles of very fine fibers, are rubbed and intertwined with your body hair when moving, the fabric may develop snags and a unique wavy texture. If you are concerned about snags, please try the following steps.
- Machine wash below 40°C.
- Use a laundry net or wash separately.
- Line dry in the shade.
- Tumble dry below 60°C.
- Do not bleach and do not use fabric softener.
- Iron on low without steam.
- Do not dry-clean.
- High temperatures may cause shrinkage.
- The fabric may develop snags due to the friction with your body hair.
