Lightweight and streamlined, the Siro 50L pack is built to go the distance. The Siro offers Kelty’s FeatherFIT™ suspension, a suspended AirMesh back panel with integrated lumbar support and hip belt.  Packing is a breeze with the center front zip panel access, and the shark’s mouth top loading design keeps all your gear easy to find once you reach your destination. The large stretch mesh front shove-it pockets offer dual entry to stash a jacket, hat, map, or whatever else you want to keep close at hand. Last but not least, the stretch water bottle pockets, external hydration sleeve (reservoir not included), and secure zippered hip belt pockets keep water and snacks easily available. From thru hikes to overnight 14ers, going the distance never felt so good.
