For runners and fastpackers, our Light 5-Pocket Shorts are even lighter and more comfortable than our regular 5-Pocket Shorts.
Made of the elastic Pertex Equilibrium fabric, they are a bit shorter than the conventional 5-Pocket Shorts and of course, make use of our unique 5-Pocket system.

Akira Natsume, Yamatomichi Founder
I personally had no complaints about our regular 5-Pocket Shorts when hiking during the hot season, but for some of our trail-running and fastpacking customers, the hiking-oriented 5-Pocket Shorts seemed not to meet the needs of the intensity of their exercise.
So I decided to create a lighter pair of shorts that allow for even easier leg movement.
The original 5-Pocket Shorts are made of non-elastic and non-polyurethane Taslan nylon. Although polyurethane is often used for its stretch property, I did not 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 fast-drying, windproof, and durable.
After trying out many different fabrics, I luckily stumbled upon Pertex Equilibrium. Though it was less durable than Taslan nylon, it had a smooth and soft texture. It also had some elasticity even though it was non-polyurethane.
For more comfort and faster drying, we updated the drawstring material of the waistband from flat to mesh. The length of the shorts is shortened for easier movement of the legs. Of course, our 5-Pocket system is inherited from the trusted 5-Pocket Shorts, so you can comfortably dig your hands in the side pockets and easily stow your map or smartphone in the other pockets.
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 Shorts. 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 dry 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 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 Shorts shows 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 standard 5-Pocket Pants/Shorts, the origin of the series; the Light 5-Pocket Pants/Shorts, that are super light and offers exceptional breathability; and the DW 5-Pocket Pants/Shorts, which are somewhat in the middle between the two.
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 Shorts and Pants uses a lightweight Pertex Equilibrium, weighing only 55 grams per square meter, achieving a significant weight saving (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 fabrics 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.
