so what is the pros and cons comparing down and synthetic bags? Im just wondering what makes one better than the other.

When I use to camp alot i was always portaging when canoeing. i never really had to hike that much. just to the next water. i always used a external frame pack and havent camped in the mountains before. I have never used one without an external frame. are non external frame packs that more comfortable than ones with the external frame? do they handle the load as well?

Think im going to go with a one man tent. the one im looking at is around 3.5lbs
