Material: 210D Robic HT nylon, 100D Robic HT nylon, Barrier DWR treatment Volume: 55L (3356cu in) Support/Suspension: frameless Shoulder Straps: dual-density padded, dual sternum straps (removable) Waist Belt: Re-Fit, removable Earning its place in the ultralight category, the Granite Gear Virga3 55L Backpack is filled with innovations that minimize mass. Rather than letting the weight of a frame sheet, stays, or back panel foam weigh us down, the Virga3 load assists with suspension. Dedicated panels stash our sleeping pad at our back to provide support and shape. Compression straps at the top, front, and sides secure our equipment, ensuring the best balance as we endure the outdoors. And ultralight doesn't have to mean ultra-weak: Robic nylon fabric keeps our gear protected from rugged rock faces and unexpected weather.
