A tough, stylish, and packable lightweight coat that can be worn in three seasons.

When you're caught in a torrential downpour that an umbrella can't protect you from, or a sudden guerrilla shower, a packable raincoat is the perfect solution. It's a coat that can completely change your look just by putting it on, and a raincoat is an essential item for the rainy season.

The raincoats I'm introducing today are not only perfect for wearing to work on rainy days, but they're also packable, making them versatile enough to pack in your bag for business trips or in your suitcase for travel. Their ability to be worn for three seasons, from spring to autumn, is another attractive feature.

Also, keep an eye out for "business casual" outerwear that can be used as rainwear.

When thinking of outerwear for rainy days, "rubberized" materials come to mind, but their drawbacks are that they are heavy and can easily cause the body to become sweaty. For hot and humid climates, it's best to choose a high-spec outer garment made of a 2-3 layer structure material such as Gore-Tex®, which allows sweat to escape from inside the garment while protecting against rain and wind.

At Isetan Shinjuku Store, Men's Building 6th floor, the contemporary casual section offers a wide selection of outerwear with functionality suitable for the upcoming rainy season. Many of the brands are derived from outdoor wear, and the lineup boasts not only high specifications but also meticulous attention to design, silhouette, and details.
I want to use this as everyday wear that allows me to stay comfortable even on rainy days, both for work and leisure.
