Thank you for viewing! We are introducing men's long-sleeved training wear. Feature 1: Pursuit of quick-drying & breathability! Golden ratio of 65% polyester, 30% nylon, and 5% spandex.

Based on ergonomics, it withstands intense movements and achieves elasticity and a great fit. Feature 3: The back design is the key! Stylish back design - follow my back(^^♪ Product Details Size: XL size. Please refer to the photos for recommended sizes. Material: 65% polyester, 30% nylon, 5% spandex Color: Blue系 (Blue-based) *The appearance may differ slightly depending on the pixel count and device. Also, please note that imported products may have different quality standards than Japanese products. Great for various uses such as training, jogging, walking, running, weight training, and fitness! Also recommended for outdoor activities, mountain climbing, cycling, and on-site work! My personal experience: I use this when I do sports like snowboarding and running. Especially for snowboarding, I use this one layer with my outerwear. Maybe my outerwear is warm, but anyway, I always feel dry even when I sweat. Also, the durability is amazing. I've washed it about 200 times so far, and it hasn't stretched, and I like that it's durable! When staying overnight for snowboarding, it's good to have both black and another color like blue for a change! It has become an absolute must-have item for me now. I think you'll understand once you wear it. I'll say it clearly: you don't need to pay for the brand. Good things are good even if they are cheap!
