Yamato Michi Alpha Best Kangaroo
■Excerpt from the manufacturer's description
*Important Safety Information*
While it is lightweight and warm, the construction—which features a brushed fleece layer embedded in a mesh fabric—means that shedding may occur due to wear during use or washing.
■Alpha Vest Kangarooの特徴
・The pockets and back panel feature Shadow Rip, a lightweight fabric with moderate wind resistance
・The body is made from Polartec Alpha Direct (136 g/m²), the same fabric used in the Alpha Vest
・Protects the abdomen from the chill of the wind, reducing the need for a shell
・Same lightweight and compact design as the Alpha Vest
・Great for active wear or as lightweight thermal clothing
・Maintains a certain level of warmth even when wet and dries quickly
Alpha Vest: Enhanced abdominal warmth and wind protection
The Alpha Vest, YAMATO's most minimalist active insulation piece, now features a kangaroo pocket.
The front is made of thick Polartec Alpha Direct (136 g/m²) fabric, which combines excellent thermal insulation with breathability to prevent moisture buildup and overheating during activity. The kangaroo pocket, featuring Shadow Rip fabric with moderate wind resistance, protects the abdomen from wind chill. Meanwhile, the back and shoulders are intentionally finished with lightweight, breathable Shadow Rip fabric alone, helping to prevent moisture buildup even when wearing a backpack.
Minimal protection for hikers who don’t want to stop walking—not even long enough to put on a shell.
○ Insulation on the front panel only
Since the back and shoulders tend to get hot when carrying a backpack during activities, and you’re less likely to feel the cold at night because you’re in close contact with your sleeping pad, we’ve intentionally placed the highly insulating Polartec Alpha Direct fabric only on the front panel, while using ultra-thin, highly breathable Shadow Rip fabric on the back and shoulders.
○ A kangaroo pocket to protect your abdomen from the cold
If your abdomen or internal organs get cold while hiking, you could, in the worst case, become unable to move. That’s why the Alpha Vest Kangaroo features a kangaroo pocket made of Shadow Rip fabric—which offers moderate wind resistance—positioned over the abdomen. By placing items such as a hand towel or a map inside the spacious kangaroo pocket, you can further enhance warmth and wind resistance, protecting your abdomen from the cold.
○ Comparison of Thermal Insulation Properties
The 136 g/m² Polartec Alpha Direct fabric used in the Alpha Vest Kangaroo offers superior warmth compared to many other active insulation materials, making it useful not only during activity but also as a base layer when you’re stationary.
○ Exceptionally high breathability
High breathability is achieved by using Polartec Alpha Direct directly as the outer fabric.
It keeps you warm without trapping heat or moisture, allowing you to move about comfortably.
○ Excellent quick-drying properties
Both Polartec Alpha Direct and Shadow Rip, the fabrics used in the Alpha Vest Kangaroo, feature quick-drying properties that allow them to dry quickly even when wet from sweat or rain.
○ Retains heat even when wet
Polartec Alpha Direct does not easily absorb water, and even when wet, it retains its loft; therefore, like synthetic down, it is less likely to lose its insulating properties when exposed to sweat or light rain.
■Details of Each Part
・Weighing just 80 grams, it’s lighter than a T-shirt, and when folded, it’s about the size of a 350-ml can.
・A drawstring that can be tightened with a single pull prevents the hem from riding up.

■Product Care
・Wash using a mild detergent in water no hotter than 30°C.
・Please wash this item on its own or place it in a laundry net.
・If the back of this product comes into prolonged contact with light-colored wool or silk garments while damp with sweat, substances in the sweat may cause color transfer.
・If the garment becomes sweaty, please wash it after wearing it.
・Do not use fabric softener or bleach.
・Do not iron or dry clean.
・If the fabric sheds noticeably when you first purchase it, please wash it once.
■Caring for Faded Fleece
The brushed fabric used in Yama to Michi’s Active Insulation is lightweight and highly breathable, yet provides just the right amount of warmth.
However, repeated use may cause the nap to flatten, which could reduce the fabric's insulation properties.
In that case, please gently brush the fabric in the direction of the nap using a metal brush designed specifically for stuffed animals.
*This care method is designed to restore the nap and improve insulation. However, fibers that have fallen out due to wear and tear will not grow back.
*The effectiveness of the heat retention restoration may vary depending on how the product is used.
*Please note that the images shown are provided by the manufacturer, so the actual product may differ slightly in terms of specifications (such as logo placement, color, or pattern placement).
