Cool. Fits well. Comfortable. Streamlined. With its easy-to-adjust suspension system and ergonomic shape, the Half Dome was created for high-intensity climbing. Be it ice, trad or big wall, the Half Dome stays put as you wriggle your way up routes and keeps you cool in the process with its unique ventilation-enhancing design. A raised brim keeps rain off your face, while low-profile headlamp clips keep things trim and functional.
