Product Description
Yamato Michi 100% Light Merino Sleeveless (Women's)
■Excerpt from the manufacturer's description
○ Changes to the 2026 Model
We revised our dyeing method, switching from “yarn dyeing”—where the yarn is dyed before weaving—to “fabric dyeing,” where the fabric is dyed after it has been woven.
*Precautions for Use*
〇 About Color Transfer in Fabrics
Please be aware that this product may cause color transfer if it rubs against white or light-colored shirts that are wet from sweat or rain.
〇 About Using the Dryer
You can use the dryer on a low-temperature cycle (maximum 60°C). However, since this can cause the fabric to pill or shed fibers, please avoid using it too frequently.If moisture evaporates while the fabric is folded or wrinkled, the wrinkles will set once the garment cools. Therefore, do not use a laundry net; instead, dry the garment on its own or in a machine with ample space. Remove the garment promptly after drying.
*Note: Using a dryer will shorten the garment by 1–2 cm, but this can be corrected by washing it again and hanging it to dry.
■ 100% Merino—Perfect for Rigorous Activities
A slim-fit, lightweight (150–155 g/m²) merino sleeveless top ideal for trail running and challenging hikes.
With the soft feel unique to 100% merino wool, powerful natural odor-neutralizing properties that keep it odor-free even after days of wear, and temperature- and humidity-regulating features that keep you “cool in summer and warm in winter,” this garment ensures your comfort at all times. Plus, it’s safe to put in the dryer (up to 60°C), so be sure to pack it for your next long trip.
Of course, it also looks great paired with a Yama to Michi trail shirt.

*From the manufacturer's website*
*Due to the nature of the fabric, some stretching or shrinking may occur after washing; however, the garment has been tailored to account for this expansion or contraction after washing and drying.
*The figures above are for the product in its unwashed state at the time of purchase.
*Due to the nature of stretchy knit fabric, there may be individual variations of 1–2 cm in the product.
*Due to the nature of the fabric, there may be slight variations in shrinkage from item to item. Shrinkage may also vary depending on the type of washing machine and the wash cycle selected.
*Using a dryer on a low-temperature setting may cause the garment to shrink more than it would if air-dried, but this can be remedied by washing it again and hanging it to dry.
*If you notice shrinkage after washing and drying, you can fix it by stretching the garment while ironing it with a steam iron.
■Product Care
・Merino wool can become prone to moth damage if body oils build up. Please wash it regularly.
・When storing the item, please use moth repellents and take measures to keep it in an airtight container to prevent insect damage.
・Yama to Michi’s 100% merino wool fabric is resistant to shrinkage, so it can be washed in a washing machine using a “delicate cycle” or similar setting designed to gently wash delicate garments with a gentle water flow.
・Regular detergents remove too much of the natural oils found in wool, which can cause the dye to run and lead to color fading. When washing, please use a neutral detergent designed for delicate fabrics.
・Because the fibers are short, pilling and fuzz may occur; however, as you wash the item, some of the fuzz will shed, and pilling will become less likely.
*Please note that since we are using manufacturer images, the actual product may differ slightly in terms of specifications (such as logo placement, color, and pattern placement).
