They are ideal for outdoor activities like hiking, skiing, or running in the rain. These beanies often feature a snug fit and can come in various styles and colors. Some may include additional features such as reflective elements for visibility or ear flaps for extra warmth. Waterproof beanies are popular among outdoor enthusiasts and are a practical accessory for cold, rainy weather.
