So you’re ready to take the next step. You’ve gotten your pack weight down to 30 pounds or less. The Granite Gear Vapor Trail Backpack uses a high-density polyethylene frame that helps distribute the load evenly over your back and onto your hips. This pack has fixed (not interchangeable) shoulder straps that are well padded and it comes standard with the Ultralight Packer hip belt available in a range of sizes for men and women. The pack is fully hydration compatible with an internal sleeve and port.
