The Swing 700 is a realistic 3 season down bag. The construction is a tuck stitched continuous baffle construction. The tuck stitch, fixes the baffles to the outside and inside shell, by stitching though two layers of fabric, which is a extremely solid. The Swing offers a well shaped hood that, together with a efficient draft collar, offers a effective closing, minimizing heat loss in low temperatures, yet at the same time allows the bag to offer a great ventilation possibility in higher temperatures. And the raised foot box offers a maximum protection for the feet with a nice feel of comfort. But the real beauty of the Swing is a the balance between the sure volume on the body section and the sure volume on the leg section. You have the double comfort of a large general volume, with the same feeling of over space on the body and leg section.
