I'm new to bushcraft and am looking for some advice on the size/type of rucksack for 3 days in the English countryside. I'm working to a budget and looking for a cost-effective solution.
As beenn said, a 50ltr bag is enough to hold a basic setup for an overnight or short trip. In my opinion the main question is what you will do for food and water. You can make do with one t-shirt for a few days. One tin of beans? If you have access to supplies while out and about then 50ltr is no problem. If you don't and you have to carry in everything then it may not be enough.
As a minimum your looking at 2ltr of water a day, which is 6ltr. If you are exerting yourself you'll need more. 1ltr of water is 1ltr in volume in the bag.
Food my be a litre or so in volume per day. This all depends on what type of food you take and how hungry you get. Dehydrated Is an option if you have access to water. If you don't then you may as well take hydrated food, as you would need to carry water to make up the hydrated meals anyway.
Good advice from been, post up your kit list and it'll help.
Good idea ditching the cans, as long as your zip-lock backs are good and sturdy. The last thing you will want is you entire dry bag of food coated in the contents of 1 bag of beans. You can do the same with a home cooked meal (chilli or spag bols), far cheaper and far nicer that a bought boil in the bag meal, just dont leave it sitting at the bottom of the cuppboard for a year!!!
So you got food and water sussed out for quite minimal pack space. Whats your sleeping arrangement gonna be?
If you mean me is not my post
