I am selling this item because I purchased it in 2021 but have hardly had a chance to use it. This cap is designed for stress-free comfort. It is soft, shape-retaining, lightweight, stretchy, water-resistant, water-repellent, breathable, wrinkle-resistant, and seamless, with a single-layer construction. It's so waterproof that you could scoop water with the cap. The soft, shape-retaining brim allows you to fold it up and store it in your pocket while running. Seller: Mashur Co., Ltd.
