I've been looking at sleeping bags for hiking here in new england in the winter and the choices are endless, I feel I'm gonna end up with a down bag for weight and its durability.Oh yaeh warmth to. The dilemma is wich brand, and degree level. I borrowed a friends 0degree last year and that was not to bad, this year he's going to be able to join me for some hikes so the dilemma is I need a good bag for New England winter. The prices seem to vary from in between 400 and 600 dollars so price shock is gone I'm quite willing to spend the money as long as the product is what it claims. You folks out there with the winter camping experience your opinions would be greatly appreciated and looked into.AT this point in the game I use a marmot 30 with a bag liner at times. I'm also looking into a 4 season tent still haven't got over that sticker shock yet. Again prices very dramatically, but I am really taking a hard look into the hiilberg line. Again thank you for you experience and sharing with us less experienced..
