I purchased this several years ago but never had the chance to wear it, so I've been storing it. Below is the manufacturer's information: Product Information: Shimano SHIMANO DURAST WJ-041T Fishing Wear Mid-layer that works well with rain gear and cold weather gear. Uses DURAST knit fabric, Shimano's unique material with windproof, breathable, water-repellent, and stretch properties. This light and warm jacket can also be conveniently used as an outer layer in relatively warm seasons like early autumn. It also has moderate stretch, making it easy to move in when casting or hooking. In winter, wearing it under rain gear or cold weather gear will increase warmth. The simple, hoodless style makes it easy to layer without bulk, and it can be worn for three seasons, from autumn to early spring. Reference weight (g): 395. Material: 82% polyester, 18% polyurethane (breathable windproof processing). It will be shipped folded compactly. #WJ-041T
