What do you use? Planning a 3 day hike in Eastern Canada . No tent, no fires. should be -7C (19F) at the coldest. Im looking at the American Branded Hotcore T-300 ( -20C [-4F] )but it seems too light and inexpensive to be true and since im in Canada its not a very popular brand. Any info would be appreciated.
