Lightweight, streamlined, and built for women, the Sira 45L women’s pack is designed to go the distance. The Sira offers Kelty’s women’s specific FeatherFIT™ suspension, a suspended AirMesh back panel with integrated lumbar support and hip belt. The shoulder straps, hip belt, and back panel are specifically designed to fit a woman’s body. 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.

  1. You need this pack

    I’ve had this for a year now and I’ve used it in various capacities. From being used as a carry-on bag for 2 weeks in Europe to 3-day backpacking trips in backcountry this pack has been so solid. It stretches so much and the zipper is very beefy. It fits very well and is comfortable even after 20-something miles. This was my first Kelty product and now I’m very much a fan of their company in general. on May 28th 2018
