Incredibly comfortable and ventilated tensioned mesh backpanel with added adjustability for variations in torso length to provide fine-tuned customization fit for every hiker and backpacker. Users can't feel seams that don't exist, and because there aren't any on the Stratos/Sirrus updated hipbelt, hikers can focus on the journey instead of the pack on your back. Hope for bluebird weather but know you're covered with our integrated and removable raincover that stows in its own pocket when the sun returns.Dual side compression strapsStow-on-the-Go™ trekking pole attachmentDual side stretch mesh pocketsIce tool loop with bungee tie-offIntegrated raincoverZippered hipbelt pocketsInternal hydration reservoir sleeveRemovable top-lid with zippered slash pocketFront panel pleated fabric shove-it pocketDual vertical zippered slash pocket on front panel
