The sleeping bag is the same as the materials here with the Mountain series, only cut differently. Down far and above with two zippers (one side to footwell, to other hip), so that one easily comes in and a sofa feeling has as in a bed. The classic mummy bags are too umbequem mostly because I like to turn at night and there is not always want to rotate the whole bag. Also you can move your legs and arms as well. The materials and workmanship are very high quality, to take from the bottom with a water-repellent coating and interior very pleasant - very different from the usual in D branded products. Color is also great - down a darker lush green, above etws brighter. The length fits with us (171 cm and 185 cm) perfectly, the flap in the neck is not too tight and also give blankets feeling and keeps the warm air inside. He also holds great warm, without you sweat, even if I have the freezing Nocht not tested. Priced also top, comparable quality there of the top dogs in D only for much more than doubled. I have been staying finally found a high quality and cozy sleeping bag, in which everything fits. Highly recommended!
