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.

These Light 5-Pocket Shorts are offered at 20% off as a special offer for models prior to a minor 2026 update.

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.

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.

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 show that it is only 0.3% of water content after 15 minutes of spin-dry, which means it is almost completely dry.

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.

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.

※Due to fabric stretch and sewing discrepancies, there may be differences between actual measurements and the dimensions stated.
※Shrinkage of the fabric may occur with wear and washing, causing dimensions to change over time.

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.

• Machine wash below 40°C.
• Use a laundry net or wash separately.
• Line dry in the shade.
• Tumble dry below 60°C.
• The heat of the tumble dry may cause shrinkage but will be restored with use.
• 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.
