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.

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.

5-Pocket Lineup

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.

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.
