What to Pack for a High Altitude Trek: Gear & Packing Guide
Packing correctly for a high-altitude trek can make the difference between a lifetime adventure and a miserable experience. When you ascend above **10,000 feet**, weather changes rapidly, temperatures plummet, and carrying unnecessary weight becomes exhausting.
Here is the ultimate gear checklist and packing strategy for high-altitude trekking.

1. The 3-Layer Clothing Rule
Avoid heavy cotton sweaters. They absorb sweat, take forever to dry, and will make you freeze. Instead, use synthetic layers that you can add or remove as you walk.
- **Base Layer:** Moisture-wicking thermal top and bottom (merino wool or polyester).
- **Mid Layer:** A warm fleece jacket or a light pullover to trap body heat.
- **Outer Shell:** A windproof, waterproof jacket and pants (Gore-Tex or similar) to shield you from rain and snow.
- **Down Jacket:** A thick down jacket is essential for staying warm at campsites when you stop moving.

2. Footwear & Socks
- **Trekking Shoes:** Buy sturdy, high-ankle shoes with deep Vibram-style soles. Ankle support prevents sprains on rocky trails.
- **Socks:** Pack 3-4 pairs of synthetic or woolen socks. Keep one pair dry, reserved exclusively for sleeping in the tent.
- **Camp Sandals:** A light pair of slippers or sandals to let your feet breathe once you reach the campsite.

3. Head & Hand Protection
- **Sun Cap:** Essential to prevent sunburns under the harsh high-altitude sun.
- **Woolen Beanie:** Covers your ears and prevents heat loss at night.
- **Gloves:** One pair of thin fleece gloves for walking and one pair of thick waterproof gloves for snow.

4. Backpacks & Packing Tips
- **Main Backpack:** A 50 to 60-liter backpack with a strong padded hip belt.
- **Daypack:** A small 20-liter daypack if you plan to offload your main bag onto mules/porters.
- **Dry Sacks:** Pack your clothes and electronics in waterproof plastic bags inside your main pack.

5. Electronics & Personal Hygiene
- **Power Bank:** Batteries drain extremely fast in sub-zero cold. Keep your phone and power bank wrapped in warm clothes inside your pack.
- **Headlamp:** Crucial for night navigation and early morning summit climbs. Hands-free lighting is much safer than hand-held torches.
- **Biodegradable Wipes:** Water is freezing at campsites, making wipes your primary way to stay clean.
