Like its namesake hummingbird, the Gregory Rufous Backpack is light, speedy, and feeds on delicious nectar. If nectar's scarce, it will also gobble up miles of trail without a second though. Weighing in at just over one pound, the Rufous has enough room to hold a two-liter reservoir, two water bottles, and a windbreaker or rain layer without making you feel like a lumpy monkey is trying to ride you like a rodeo bull. All your snacks will fit in the dual waist-belt mesh stretch pockets, and the front water bottle pockets are easy to reach when you're on the move. The Rufous rides smoothly, too, with a Bio-Sync suspension system that features an ergonomically-molded back aero-mesh panel with strategic foam inserts and a flexible strap-to-pack connection that allows the straps to move without jerking the pack around and throwing you off balance.
The Gregory Rufous Backpack was designed with input from Gregory sponsored athlete, Hiroki Ishikawa. This ultralight, runner's specific day pack features twin water bottle pockets on the front of the pack so you can quickly and easily reach bars, gels, water or whatever else you've stored inside. Also a great choice for your next adventure race!FEATURES: BioSync Technology system Aero-Mesh backpanel Adjustable sternum strap Hydration port and sleeve with back-fill access Tube management system Internal on-the-fly compression system Dual, stretch-mesh waistbelt pockets with cargo stabilizer loops Twin water bottle pockets Reflective webbing loops Internal mesh organizer and pocket with Velcro closure Key clip and reflective accents SPECIFICATIONS:Volume - 480 cu in | 8LWeight - 1lb 1oz | .48kg
