Yamato Michi Merino Short-Sleeve Shirt (Men's)
■Excerpt from the manufacturer's description
○ 100% Merino Trail Shirt
Made from high-quality New Zealand wool and woven in Italy, this lightweight, breathable fabric isn’t as warm as a typical wool shirt. Thanks to its powerful natural odor-neutralizing and moisture-regulating properties, it always feels fresh and comfortable against the skin.
With its wide fit and open collar, this shirt prevents you from overheating. You can unbutton the front all the way for ventilation or button up the collar and stand it up when it’s cold—thanks to the unique details of Yama to Michi’s trail shirt, you can freely control wind resistance and your body temperature.
・Powerful natural deodorizing properties
・Cool in summer and warm in winter, with natural humidity-regulating properties
・Shirts for the trail
■The Drawbacks of Wool
While merino wool has excellent properties and features, it does, of course, have its drawbacks. Please be sure to understand both the pros and cons before wearing it.
・Absorbs water and becomes heavy
Because it has a high moisture content and absorbs a lot of water, it takes longer to dry than synthetic fibers. However, quick-drying fibers generate latent heat as moisture evaporates, which carries the risk of rapidly drawing heat away from the body. That said, when comparing fabrics of the same thickness, they do dry faster than cotton.
・Prone to insect damage
Soft animal fibers such as wool, cashmere, and silk are particularly attractive to clothing pests.
・Prone to developing holes from friction
Because wool fibers are short, they tend to shed easily when rubbed, causing the fabric to thin out and develop holes more readily than synthetic or cotton fabrics.
・Prone to shrinking
Although wool is known to shrink easily when washed, even washable wool that has been treated to resist shrinking will still shrink to some extent.
・Distortion is likely to occur due to skewing
Due to the nature of knit fabrics, washing causes the fibers to swell, creating a force that tries to reverse the twist. This can cause the fabric to distort diagonally, resulting in a warped shape.
・It has that distinctive wool smell
Due to the nature of animal fibers, you may notice a distinctive odor when the fabric is damp—such as after spinning during the wash cycle—but the odor will disappear once it dries.
