Last summer was our first summer of camping and I had bought us all new sleeping bags, well I hated mine and our DD refused to sleep in hers and ended up using it as a duvet on top of her. DH doesn't mind either way, so I'm thinking about taking our duvets this summer. We are a family of four so the way I figured is two double duvets rather than single ones. The duvets are huge though, 13.5 tog, they would take a lot of space in the car compared to the sleeping bags. I tried and failed to squeeze them in to the compression bags so what are my alternatives? How can I pack them compact or do I just stick to the sleeping bags? What do you take with you and if you take the duvet how do you pack it in the car?
