Synthetic sleeping bags can typically last for 5-10 years with proper care and maintenance.
Both synthetic and down bags have very different qualities, strengths and weaknesses. Synthetic bags are less expensive to manufacture and therefore are normally cheaper to buy. When wet they are also less likely to lose their vital insulation properties, unlike down sleeping bags. Down bags are generally much warmer than their synthetic counterparts but great care must be taken to look after them. When they get wet they will lose a lot of their insulation properties. It is recommended to take them to a specialist cleaner rather than wash them in your machine. Often more expensive than synthetic bags, they also last a lot longer. Down works by the feathers building on the insulating layers being warmed by body heat. Both have differing qualities and can been seen here - http://www.outdoorleisure101.com/sleeping-bag-reviews
Sleeping bags typically last for about 5-10 years before needing to be replaced, depending on the frequency of use and quality of care.
Depending on where exactly you're going on your next excursion, the types of sleeping bags you'll look into will probably differ drastically. For example, if you're going out somewhere very cold, then you will likely want to consider looking at down sleeping bags. However, if it's going to be raining a lot as well, you may want to stick to the synthetic sleeping bags since they work much better in wet conditions. The last thing you want is to be stuck out in the middle of nowhere with a wet and cold sleeping bag. This kind of thing can totally ruin your trip.
Down sleeping bags typically last around 10-15 years before needing to be replaced, depending on usage and care.
