Introduction
Even Thinner and Lighter, 5-Pocket Shorts
A lighter version of the 5-Pocket Shorts.
The Pertex Equilibrium fabric offers exceptional lightness and quick-drying performance, keeping you comfortable even in the hottest seasons. Five pockets are smartly placed to avoid hindering leg movement, efficiently storing items like your smartphone or a map.
With a barely-there feel, these shorts let you move freely and walk lightly wherever you go.
Form and function
Differences from the Light 5-Pocket Short Shorts
With a length 1.5 cm longer than the Light 5-Pocket Short Shorts, they offer added coverage while keeping the same sleek silhouette as the 5-Pocket Shorts and DW 5-Pocket Shorts.

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 a water bottle.

1st pocket
The side pockets are designed so that you can comfortably put your hands in them.
2nd pocket
The 2nd pocket is perfect for your smartphone. The perfectly-allocated pocket just behind the hipbone secures a smooth leg lift, preventing your phone from bouncing around and keeps your phone safe and intact when sitting.
3rd pocket
The 3rd pocket is positioned high for wallets, etc. The long zipper tab allows for easy opening/closure of the pocket.
Key loop
You can attach keys or a small carabiner to the long key loop. It’s also handy when you hang the pants to dry.

4th pocket
The lower part of the pocket liner is made of polyester mesh for drainage should the pants get wet.
5th pocket
The 5th pocket is made to fit the size for the normal hiking map. It is also convenient for putting trash during hiking or keeping snacks close at hand. The pocket can also hold a large screen smartphone.
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.
Super Fast-drying
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 show that it is only 0.3% of water content after 15 minutes of spin-dry, which means it is almost completely dry.

5-Pocket Lineup
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.
Material
Pertex Equilibrium
Pertex Equilibrium, with its unique double-weave construction, features thicker yarns (bundles of fibers) woven at regular intervals on the inner side in a striped pattern. This creates a textured surface that lifts the fabric off the skin, improving breathability and reducing clinginess and discomfort. Despite being thin and lightweight, the use of thicker yarns in the ripstop structure on the inner side enhances durability.
The fabric also offers a slight stretch thanks to the use of “false-twist yarns,” where the weft yarns are crimped to provide elasticity, allowing for unrestricted movement such as high steps. Additionally, blended yarns of nylon and polyester are used in some areas, and the differing dye affinities of the two fibers create a subtly mottled, heathered texture.

Notes before use
Durability
Pertex Equilibrium used for the Light 5-Pocket Shorts is extremely thin and lightweight.
While the ripstop structure provides a certain level of strength, contact with sharp objects such as rocks or branches may cause small punctures that can lead to tearing. Please take extra care when passing through rocky terrain or sitting down on rough surfaces during breaks.
