Introduction
Winter Only Hood
We’ve enhanced our simple Only Hood design by incorporating the lightweight, warm, yet highly breathable Polartec Alpha Direct, which is a fabric that is superior at preventing water retention and maintaining its loft when wet.
At only 51 grams, it is lighter than most knit caps, but warmer, and can be used as a neck gaiter or a balaclava. Making it great for light snow situations.
For optimal layering, we recommend pairing the Light Alpha Only Hood with jackets that do not have hoods, such as our: Light Alpha Vest/Jacket, Merino Coach Jacketor the 100% Merino Pullover
2025 Model Updates
- In consideration of environmental impact, we have transitioned the outer fabric’s water-repellent treatment from C6 DWR to C0 DWR.

Form and function
Balaclava
Transforms to a simple balaclava that can completely cover the nose, a great feature for when in harsh cold conditions.
*Does not have the elastic fitting feel like most balaclava’s do.
The front length of the hood is longer than that of the Only Hood so that the neck is completely covered when worn as a balaclava.
Warmth
Although it’s not as warm as 1000-fill-power down, the Polartec Alpha Direct (85g/m²) used in the Light Alpha Only Hood is one of the best insulators available—arguably even warmer than wool. Its exceptional warmth-to-weight ratio, combined with superior breathability and water resistance, makes it an excellent choice for active use in varying conditions.
Comparative test
The below chart compares the 1000 fill power down and other insulators used in thermal clothes on the market.
- Heat retention is measured by JIS L 1096 A method, in Yamatomichi in-house test. The heat insulation property is measured from the amount of energy consumed by the heat-generating element to maintain its temperature. The maximum value is 100%.
- The values of Polartec and Primaloft fabrics are the manufacturers’ catalog specs. Other fabrics’ values are measured by Yamatomichi. 1000 fill power down includes its 7 denier nylon outer and lining.
Fast-drying
Polartec Alpha Direct offers some of the best quick-drying performance among the mid-layer fabrics we use at Yamatomichi.
Comparative test
The below chart compares the fast-drying performance of middle layer products. You can see that the Alpha Direct is not as fast-drying as the extremely fast-drying Shadow Rip (UL Shirt), but the moisture content after spin-dry is much lower than that of wool and other fabrics, and even when wet, it dries quickly if lightly wrung out or worn for some time.
*A proprietary test: We looked into the difference of the water content after a 15 minute spin-dry. The larger the value, the higher the moisture content, meaning slower-drying.

Material
Polartec Alpha Direct
Conventional natural down and synthetic insulators tend to contain body moisture within the clothes and as a result, can be quite stuffy. Polartec Alpha Direct, on the other hand, is so air-permeable that it can be worn even during a high level of physical activity.
Alpha Direct is also treated by Polygiene odor control which safely reduces the microorganisms and bacteria by small amounts of silver ions, achieving antibacterial and deodorizing function that well exceeds the lifespan of ordinary garments.
It is like a fleece with longer puffy hairs.
Pertex Quantum Air
To make the most of Polartec Alpha Direct’s outstanding breathability, we use Pertex Quantum Air as the shell fabric—a super-lightweight, highly air-permeable nylon treated with a durable water-repellent (DWR) finish.
To achieve its high level of breathability, Quantum Air is woven at an extremely loose density. By using low-count yarns that are less prone to friction, the fabric resists wear from rough materials like hook-and-loop fasteners. The yarns are also false-twist processed, giving the fabric a balance of light stretch, breathability, and durability.
On the inside, we apply Yamatomichi’s ultra-thin titanium sputtering—a process that bonds a microscopic titanium layer to the fabric surface. This helps retain body heat and reduce radiative heat loss while preserving the fabric’s natural feel and breathability, achieving a high-level balance of ventilation and warmth without compromise.

Instructions
Care instructions
The titanium coating on the back of the fabric can gradually wear off due to friction caused by daily washing. The proper care with the right washing method can help maintain the titanium coating.*
*The amount of titanium particles washed away is minimal and considered to be harmless for the environment.
- When machine washing, set to gentle or delicate, avoid damage caused by contact with other laundry by washing separately or using a laundry net.
- Avoid bleach or detergent that contains enzymes as they might discolor the fabric due to the chemical reaction with the metal. Use neutral detergent.
- Do not soak in detergent for a long period of time as it can accelerate the delamination of the titanium coating.
- Wring gently after washing and line dry in the shade.
- Do not iron. Do not dry-clean.
- If necessary, wash to remove fuzz from the fabric before first use.

Restoring loft and warmth
The lofted fibers used in YamatoMichi’s active insulation are lightweight, breathable, and provide comfortable warmth. However, with continued use, these fibers can become flattened, which may reduce warmth.
If this happens, gently brush the fibers in their natural direction using a metal stuffed-animal grooming brush. Our internal testing shows that this simple care method can help restore loft and improve warmth.
At YamatoMichi retail stores, we offer in-store brushing support, and staff can show you how to do it properly. If you’re unsure about caring for your item at home, feel free to ask us for help.
*This method helps restore loft to flattened fibers, but fibers lost through wear cannot be replaced.
The degree of warmth recovery will vary depending on the condition of the product.
Before Brushing
After Brushing
What You’ll Need
- A metal grooming brush for stuffed animals
How to Restore Loft
- Lay the area you want to revive as flat as possible.
- Gently brush the flattened fibers several times in one direction.
- Once the loft stands up again, you’re done.
Notes
- Avoid brushing too hard, as it may damage the fabric.
- Only brush when the fabric is completely dry.
- The degree of loft recovery will vary depending on the material and product.
