I ask for guidance. I'm new to camping, I've camped at festivals etc, but always having different bags for tent, supplies, sleeping bag etc. I'm looking to take solo camping more seriously and need a bag to put all my shit into (tent, sleeping bag, mattress, some clothes and food, supplies). How big of a bag do I need? I read that Fjällräven KAJKA 75 is an excellent life-long bag, but it's fucking expensive and looks like wearing a full body bag on your back. Would I be ok with like a 40 litre bag? I have a pretty big tent and mattress and I also like to carry a few kilos of food with me. How small could I go and what would you guys recommend?
