Material and Craftsmanship: The cap body is made of water-repellent fabric, and the brim is waterproof, effectively blocking light rain or snowmelt and keeping the head dry. The lining and earflaps are made of faux lamb's wool, with fine, soft fleece that feels gentle on the skin and provides excellent warmth. Soft threads are added to the inside of the brim, allowing for adjustment of the brim's curvature to enhance wearing flexibility and comfort.

Warmth and Earflap Design: The earflaps fully cover the ears, and the thick, fluffy faux lamb's wool effectively locks in heat and prevents cold winds from penetrating. The distinct layers of fleece on the crown and earflaps create a stable warmth barrier, suitable for use in low-temperature environments.

Cover Shape and Details: The baseball cap design combines sun protection and wind protection. The adjustable brim with soft threads allows for flexible adaptation to different cycling needs. The cap circumference fits the head shape, and the lightweight, non-bulky design ensures comfortable wear for extended periods.

Wearing experience and style features: The overall hat design is simple, with a duckbill brim adding a dynamic style, and faux lamb's wool trim providing warmth and texture. Suitable for cycling, commuting, outdoor sports, and everyday casual wear, it combines practicality and warmth, making it an ideal winter hat with ear flaps for cold weather.
