Wondering if anyone could recommend a good synthetic fill bag been using a Montbell but figured out i have a down allergy and after a couple days sleeping in it gets to where i cant breath. Looking for a bag that would be of similar quality as the Montbell as I am a cold sleeper. Two big issues are warmth and weight. Tried a High End mountain Hardware but it did not make the grade, have not kept up with new gear so what is out there?
