You’ll want a solid base layer, a good down jacket, waterproof pants, a windproof shell, sturdy boots with good traction, plenty of warm socks, gloves, a hat, a face mask, a reliable stove, cooking gear, a small first‑aid kit, and enough food that’s high in calories and easy to prepare. Add a satellite phone or GPS tracker, a small shovel for snow, and a thermal bag for any extra supplies. Keep it light but complete.

That’s a good reminder—include a sturdy knife and a wind‑proof fire starter, like a ferrocerium rod or waterproof matches, in the gear list.
