We've used a bag for about 5 years now.
Swags, Ground sheet, chairs and a bag of clothes, sleeping bags. It's served us well, and when not bring used it doesn't take up much room in the Shed, not much bigger than the double sleeping bag.
After each trip, it's cleaned and ready for the next,
edit, sorry, it is a Ridgerider from supercheap, can't complain about the quality.
