Inertia 20L Backpack

From racing the setting sun on a post-work, evening jaunt through the foothills to bagging a peak or two in a single day, the Gregory Inertia 20 Backpack is designed for on-the-move, grab-and-go excursions. Durable and water-resistant nylon fabrics comprise this pack's construction for the rough and unpredictable terrain ahead, while the padded shoulder harness and hipbelt utilize air mesh for an ideal combo of cushioned comfort and breathability. Load lifters on the shoulder harness adjust the fit to keep the pack close to your back with increased stability, while a magnetic sternum strap clicks things into place with one hand for on-the-fly convenience. Arguably the biggest star of the show, this pack's included Hydro 3D reservoir and DryLock bite valve keeps precious H20 close by and easy to access when you're making that final push to the summit, and a multitude of stretchy pockets hold extra bottles if you don't think the bladder will be enough for your trip.
