If your overall pack load is under 30 lbs., the Meridian Vapor Ki can handle it thanks to its Vapor Suspension system. The floating lid can be converted into a hip pack or removed all together for even more weight savings. If ultralight backpacking is your philosophy, this pack would make a great addition to your gear collection. The Meridian Vapor Ki features a women's harness and belt to offer a better fit for female hikers.
