The fact is, the longer and more remote the hike is and the more inclement the weather, the more clothing, gear, food and water you’re going to want. Sooner or later we´re talking about lightweight backpacking. The most important rule: Bring less except food!
Best backpacking food is lightweight and nutritious.
It is essential enough food is taken to maintain both energy and health. As with gear, weight is critical. Consequently, items with high food energy, long shelf life, and low mass and volume deliver the most utility.
