Are you hiking in or do you have a vehicle to carry gear? Are you using a personal tent or a large tent with a heater? Either way, while the consensus is that while synthetics are usually warmer than Down when wet, a wet sleeping bag is still a wet sleeping bag and wet synthetic bags are still miserable. The more important factor is the quality of your tent, as I have been using Down for years on the wet west coast of BC. If you take care of your camp and your sleeping bag, you can keep Down dry. My sleeping bag has its own drybag and only comes out inside the tent or if the weather outside allows for airing out.
