Hi I know this kind of topic has been touched on a lot but I am new to Alaska and in the process of updating gear. Seems a lot of people prefer synthetic over down. I am looking at getting either the lamina (synthetic) or marmot ( waterproof down) what are your thoughts? The bag will be used mainly for hunting kind of want an all around bag if there is such a thing. Already updated to a four season tent now looking at sleeping bags. Thanks for the help.
