5-Pocket Shorts Light


¥14,000 Tax included


Even Thinner and Lighter, 5-Pocket Shorts

The Light 5-Pocket Shorts are the lightest of our shorts, with shorter length for ease of movement, great for runs or fast packing, and a waist adjuster that uses a flat string rather than a draw belt to keep the waist area neat.

However, we have received frequent requests for the Light 5-Pocket Shorts to have longer length, from those who want lightweight shorts but feel uncomfortable with the shorter length, so we decided to make a longer version of the Light 5-Pocket Shorts, the 5-Pocket Shorts Light available through preorder.

The 5-Pocket Shorts Light carries the same material as the Light 5-Pocket Shorts, using the thin and lightweight Pertex Equilibrium fabric, but with a slightly longer pants length. It also uses the same waist adjuster as the original 5-Pocket Shorts.

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 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 5-Pocket Shorts Light with the base layers of major manufacturers, as well as a standard cotton shirt.

The lower the moisture content, the faster it dries. The 5-Pocket Shorts Light show that it is only 0.3% of water content after 15 minutes of spin-dry, which means it is almost completely dry.


Pertex Equilibrium

The special double-weave structure of Pertex Equilibrium has a slightly stretchy (two-directional) feel due to the combination of yarns of different thicknesses, and the unevenness on the reverse side of the fabric, which decreases skin contact and prevents the fabric from sticking to you.

until the 2022 model year was specialized to be extremely lightweight, the fabric was thin, and while it was cool and comfortable in warm weather, it was prone to tearing when rubbing against rocks and other surfaces.

In 2023, We doubled the tear strength by using a wider thread for the rip-stop which increased the weight by 10% but gave the fabric a more firm texture, making it stick less to the skin. This stiffer material to our surprise helped lower heat buildup within the garment even though the fabric was 40% less breathable by value.

In addition, the previous Pertex Equilibrium had a weakness in that it was prone to snags, but we have increase the strength on the backside making it less prone to snag and reduced the likelihood of tearing.

      Relatively Weak

      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.
