Thanks for that. I haven't used bivvy bags before - I thought the saturn might offer a bit of room for cooking, and I don't like the idea of having the bag draped over legs and feet, but weight is a big consideration, and it's not cheap. I thought it looke dpretty durable thoughand reckon it might laast longer than the tent. I'm going to have a look at the weight and have a look at the weight. Cheers.
