Choose synthetic when your trips are wet forests and you cannot guarantee the bag stays dry. You pay in volume. A compression sack helps the pack and does not help the warmth. Air it out every morning.
Who should buy it. Hikers in rain who do not want to baby a down bag.
Best for. Wet climates where down is a gamble
Standout limitation. Bulky
