Hardshell jackets are waterproof and windproof outer layers designed to protect against harsh weather conditions. Made from durable materials, they often feature sealed seams and breathable fabrics, allowing moisture to escape while keeping rain and wind out. These jackets are ideal for activities like hiking, skiing, and climbing, where exposure to the elements is a concern. Typically lightweight and packable, hardshell jackets can easily be stored in a backpack when not in use. Many models come with adjustable hoods, cuffs, and hems for a customizable fit. Popular brands include The North Face, Patagonia, and Arc'teryx.
