Yamato Michi Bamboo Shirt L Gray Ash UL yamatomichi Bamboo Shirt, New, Unused, 2025, Sold Out, Gray Made in Fukushima, Japan Material: Bamboo Polyester (50% Rayon, 50% Polyester) 118g/m² Weight: 227g (Size L) 50% bamboo blend for excellent moisture regulation. The bamboo polyester fabric, a 50/50 blend of bamboo, which regulates unpleasant heat and humidity, and polyester, which offers quick-drying properties and durability, excels in absorbency and moisture absorption, creating a comfortable microclimate within the garment. In humid environments, fibers that absorb more moisture feel cooler against the skin, while in cooler environments, fibers that don't absorb too much moisture help retain hydration. The difference in moisture content between these two environments demonstrates the garment's ability to regulate the internal environment, contributing to comfort. The diagram below compares the moisture content of the fibers in humid environments (30°C, 90% humidity) and comfortable humidity environments (20°C, 65% humidity). Bamboo polyester maintains an appropriate moisture content in both environments, demonstrating superior moisture absorption compared to 100% polyester fabrics, and also possesses moisture-regulating properties that keep the inside of the garment comfortable. Will be shipped without the box, lightly wrapped, via Nekopos.
