Plus, it’s dryer-safe (up to 60°C), so be sure to pack it for your next long trip.\u003cbr\u003e\n\u003cbr\u003e\n*Changes to the 2026 Model\u003cbr\u003e\nWe 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.\u003cbr\u003e\n\u003cbr\u003e\n■Features and Design\u003cbr\u003e\n○ The Positioning of 100% Light Merino\u003cbr\u003e\nAlthough its quick-drying properties are inferior to those of synthetic-fiber base layers, it compensates by minimizing the cooling effect caused by the latent heat of evaporation from sweat, thereby reducing the risk of hypothermia due to wetness. While it prioritizes moisture absorption over quick-drying and thermal insulation over cooling, the fabric is thin and highly breathable, making it a great choice for active wear during summer mountain hikes.\u003cbr\u003e\n\u003cbr\u003e\n○ Recommended for situations like these\u003cbr\u003e\n\"There are large temperature fluctuations.\"\u003cbr\u003e\nWool has the ability to maintain a constant temperature inside clothing, keeping you comfortable even when there are extreme temperature fluctuations.\u003cbr\u003e\n\"Put on the shell\"\u003cbr\u003e\nBase layers made of synthetic fibers with low moisture-absorption tend to become stuffy inside a shell jacket because they don’t dry quickly enough; however, 100% Light Merino, with its high moisture-absorption, helps maintain optimal humidity levels inside the garment, so you’re less likely to feel stuffy even when wearing a shell jacket to protect against wind and rain.\u003cbr\u003e\n\"Long active time\"\u003cbr\u003e\nEven when synthetic fabrics are treated with antibacterial and deodorizing finishes, they start to smell a few hours after you start sweating, and you may feel reluctant to wear them the next day even after they’ve dried. Wool, on the other hand, has extremely powerful natural deodorizing properties; even after heavy sweating, the odor virtually disappears once it dries, making it relatively comfortable to wear the next day and beyond.\u003cbr\u003e\n\"I want to pack lighter.\"\u003cbr\u003e\nAs described above, since a single garment can adapt to a wide range of environmental changes, causes minimal odor, and can be worn for long periods, you can reduce the number of clothing changes and lighten your load.\u003cbr\u003e\n\u003cbr\u003e\n○ Powerful natural deodorizing properties\u003cbr\u003e\nMerino wool is said to “remain odor-free even after being worn for a week,” and it possesses overwhelmingly superior odor-neutralizing properties compared to synthetic fibers treated with odor-neutralizing agents.\u003cbr\u003e\nAlthough many mysteries still surround the mechanism behind this deodorizing effect, one theory suggests that wool has an extremely high capacity to absorb odor-causing compounds, trapping them within its fibers at levels undetectable to the human sense of smell.\u003cbr\u003e\n\u003cbr\u003e\n○ Cool in summer and warm in winter, with natural humidity-regulating properties\u003cbr\u003e\nMerino wool, often referred to as a “natural air conditioner,” regulates the temperature and humidity inside your clothes, creating a comfortable wearing experience.\u003cbr\u003e\nThis dual characteristic—staying cool when it’s hot and warm when it’s cold—is due to the “crimp” in wool fibers, which creates air pockets within the fabric to maintain high breathability and moisture permeability, and the fact that the amount of moisture absorbed by the fiber’s cortex—known as the “cortex”—varies in response to ambient humidity, absorbing more moisture as humidity increases.\u003cbr\u003e\nThe air pockets created by the “crimp” within the fibers act as loft—similar to down or synthetic fiber fill—to retain heat, providing superior insulation compared to cotton or synthetic fibers of the same weight.\u003cbr\u003e\n\u003cbr\u003e\n○ Keeps you warm even when wet and helps prevent hypothermia\u003cbr\u003e\nWhen wool gets wet, it generates “absorption heat.” Because of its low thermal conductivity, it does not easily draw heat away from the body. Even when wet, the yarn retains its elasticity and maintains the air pockets between the fibers without collapsing, ensuring that its insulating properties remain uncompromised. Furthermore, the fibers absorb moisture from the inside out, drawing it away from the skin to keep you feeling dry.\u003cbr\u003e\n\u003cbr\u003e\n○ 100% merino wool—safe for the dryer\u003cbr\u003e\nWhile many merino wool products shrink or lose their shape when tumble-dried, Yama to Michi’s proprietary 100% merino wool offers dimensional stability that allows it to be tumble-dried at low temperatures (up to 60°C). Since you can dry them in a dryer at hotels or laundromats while traveling, you can pack fewer changes of clothes even for long-distance hikes or trips.\u003cbr\u003e\n\u003cbr\u003e\n■Material：100% Merino Wool, 150-160g\/m2\u003cbr\u003e\n■Weight：\u003cbr\u003e\n・135 g (Size XS)\u003cbr\u003e\n・153 g (Size S)\u003cbr\u003e\n・168g (Size M)\u003cbr\u003e\n・183g (Size L)\u003cbr\u003e\n・193 g (Size XL)\u003cbr\u003e\n\u003cbr\u003e\n■Product Dimensions (cm) *From the manufacturer's website*\u003cbr\u003e\n[XS]　Length: 60.5, Body Width: 43.5, Hem Width: 42.5, Sleeve Length: 70, Cuff Width: 9.5\u003cbr\u003e\n[S]　Length from shoulder to hem: 64; Body width: 48.5; Hem width: 47.5; Sleeve length: 76; Cuff width: 9.5\u003cbr\u003e\n[M]　Length: 67, Body Width: 51, Hem Width: 50, Sleeve Length: 78.5, Cuff Width: 10\u003cbr\u003e\n[L]　Length from shoulder to hem: 69; Body width: 55; Hem width: 54; Sleeve length: 81.5; Cuff width: 10.5\u003cbr\u003e\n[XL]　Length: 71, Body Width: 59, Hem Width: 58, Sleeve Length: 84.5, Cuff Width: 11\u003cbr\u003e\n\u003cbr\u003e\n*Due to the nature of the fabric, some stretching or shrinking may occur after washing; however, the garment has been sized to account for this expansion or contraction after washing and drying.\u003cbr\u003e\n・The figures above are for the product in its unwashed condition at the time of purchase.\u003cbr\u003e\n・Product sizes may vary by 1–2 cm.\u003cbr\u003e\n・There may be slight individual variations in shrinkage, and it may vary depending on factors such as the type of washing machine and the wash cycle settings.\u003cbr\u003e\n・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.\u003cbr\u003e\n・If you're concerned about shrinkage after washing and drying, you can fix it by steaming the garment with an iron while stretching the fabric.\u003cbr\u003e\n\u003cbr\u003e\n■Precautions for Use\u003cbr\u003e\n○ About Color Transfer in Fabrics\u003cbr\u003e\nPlease be aware that this product may cause color transfer if it comes into contact with white or light-colored shirts that are wet from sweat or rain.\u003cbr\u003e\n\u003cbr\u003e\n○ About Using the Dryer\u003cbr\u003e\nYou can use the dryer on the low-temperature setting (up to 60°C). However, since this can cause the fabric to pill or shed fibers, please avoid using it too frequently. If moisture is removed 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.\u003cbr\u003e\n\u003cbr\u003e\n*Note: Using a dryer will cause the garment to shrink by 1–2 cm in length, but this can be corrected by washing it again and hanging it to dry.\u003cbr\u003e\n\u003cbr\u003e\n■Product Care\u003cbr\u003e\n・Merino wool can become prone to moth damage if body oils build up. Please wash it regularly.\u003cbr\u003e\n・When storing the item, take measures to prevent insect infestation, such as using insect repellents or sealing the container.\u003cbr\u003e\n・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.\u003cbr\u003e\n・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.\u003cbr\u003e\n・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.\u003cbr\u003e\n\u003cbr\u003e\n*Please note that since we are using manufacturer images, the actual product may differ slightly in terms of specifications (such as logo placement, color, or pattern placement).\u003cbr\u003e\n\u003cbr\u003e","brand":"山と道","offers":[{"title":"Cinnamon \/ XS","offer_id":52929427931421,"sku":"rc_ITFI9YHC2UO2_BQni","price":15000.0,"currency_code":"JPY","in_stock":true},{"title":"Cinnamon \/ S","offer_id":52929427964189,"sku":"rc_IT25EJIMAW66_bdUx","price":15000.0,"currency_code":"JPY","in_stock":true},{"title":"Cinnamon \/ M","offer_id":52929427996957,"sku":"rc_ITAU4O8CIXPG_bkA6","price":15000.0,"currency_code":"JPY","in_stock":true},{"title":"Cinnamon \/ L","offer_id":52929428029725,"sku":"rc_ITFV6UG5S2UI_m5GQ","price":15000.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0791\/4917\/0973\/files\/PkCkiKqjwVli8kK5ZYrwOYctSioRQpbw6YouNmwr.jpg?v=1789367160","url":"https:\/\/shop.moderateweb.com\/en\/products\/rc_itfi9yhc2uo2_bqni","provider":"moderate","version":"1.0","type":"link"}
