Jack Wolfskin Black Ice

Black Ice is a good and light sleeping bag with Gore DryLoft shell fabric. Very well made. Just a month ago I was sleeping without any tent just on my Karrimat and there was strong winds and it was raining snow. The Temperature was -15 C. When I woke up morning, The bag was completely buried on snow, there was a 5 cm thick layer of snow even on my chest, but I slept very well, just like in home in my bed. I've newer used a Fearhered Friends bag, but so far this is the best.
