You keep the core gear that covers the same need twice, but you stack it with only one extra thing. For a 48‑hour cut‑off you need food, water, shelter, a fire source, a first‑aid kit, a knife, and a signal device. Make sure you have two ways to boil water – a stove and a campfire – and two food types – dehydrated meals and high‑calorie bars. One shelter option is a tarp and a bivy sack, but keep a lightweight tarp as a backup for a rain‑shower. The knife is a single multi‑tool; the fire starter is a lighter plus a flint. The first‑aid kit is a single compact set with bandages, antiseptic, pain relievers, and a spare pair of gloves. The signal device is a whistle and a simple flare. That’s it. No extra gadgets, no extra layers. Keep everything in one compact bag, so you can move fast and stay ready for whatever comes.
