This is a GORE-TEX vest from DAIWA PIER39. It uses GORE-TEX INFINIUM™ fabrics, which offer excellent windproof, breathable, and water-resistant properties. The vest uses semi-dull recycled nylon, giving it a dry touch. It has durable water repellency and excellent breathability. Additionally, it combines Taslan yarn, known for its fluffy texture, to create a cotton-like feel, along with a 60/40-style material characterized by a classic grosgrain weave and a matte look. It's also treated with a water-repellent finish to handle sudden changes in weather. I bought this vest but haven't been able to use it much and it's been in storage. Purchased for 49,500 yen.
