Designed for those of us who love space, versatility and plush comfort, the Amplitude sleeping bag is ideal for outdoor adventurers who return to the same campsite every evening, for car camping tours or cabin expeditions. Many amplitude adjustment options help to adapt to different temperature conditions. Close all zippers and pull the internal drawcords together to ward off cold. In more summery temperatures, the zippers allow for variable ventilation settings and can even transform from a thick sleeping bag into a slim summer blanket. Vertical chambers above the chest area ensure that the high quality 750+ loft down does not move while sleeping, creating cold spots. A lateral chamber barrier maintains the 60/40 fill ratio and ensures that more down remains on the top of the sleeping bag for maximum thermal insulation. Large zipper channels prevent body heat from escaping. The specially shaped foot box and three-dimensional hood ensure that the down is not compressed. Due to the specially developed fastening system with removable straps, the Amplitude sleeping bag can be connected to all our sleeping mats. This gives you the ultimate sleeping system for maximum comfort.
