I use these meals for when I am on Land Based fishing trips hours away from shops etc...Easy to prepare in the back of the 4WD or in a tent. These are super light weight, pack down to nothing and lastly are very very tasty!!!

They have a full range of meals, breakfasts, desserts, lunches and emergency rations. All you need is hot water for the basic packs, but there is self heating packs too that only use cold water and a chemical reaction process to warm the food. They come with water sterilization tablets too if the water source is a bit dodgy
