after 5 days in the mountains, I can claim to have made the purchase of the year the sleeping bag. Despite low temperatures but in the hut at night (about 15 degrees) you do not need another blanket. the sleeping bag is very comfortable, spacious ('m 1.90m) and, moreover, light and very small. only the closure with a Velcro 1x1cm sized a little short, a little bigger or just a push button would be better there. still 5 stars!
