Deuter Futura Vario 50+10L Hardly used. Used only for a 3-night, 4-day mountain trip. The VariSlide system allows for easy adjustment of the back length. The Aircomfort Sensic Vario mesh back provides maximum breathability. The Active Fit shoulder straps conform well to the body shape and movements. The hip fins have pads that gently fit the hip bones, preventing slippage during activity.
