How heavy should my pack be?

Aim for 8-10kg. Every extra kilogram feels like three once you pass 3,000 meters in elevation.

Do I need expensive down gear?

If you are trekking in regions like Nepal or the Andes, you can often rent a high-altitude down jacket locally for a fraction of the cost.

Packing for High-Altitude Trekking

Pack using a three-layer system—base, mid, and shell—to manage temperature fluctuations between 5°C and -15°C. Keep your pack weight under 10kg by prioritizing multi-use gear and merino wool fabrics that resist odors.

Build the layer system. Pack one synthetic or merino base layer, a heavy fleece or down mid-layer for heat retention, and a high-quality hardshell jacket that is windproof and waterproof.
Protect your extremities. Bring two pairs of thick wool-blend trekking socks, a warm beanie that covers your ears, and heavy-duty gloves. Never rely on thin cotton socks, as they cause blisters when damp.
Select your footwear. Bring broken-in, waterproof hiking boots with high ankle support. Ensure you have at least 50km of wear on them before the trip to prevent debilitating blisters.
Manage your hydration and electrolytes. Use a 2-liter insulated water bladder to prevent freezing hoses. Pack electrolyte tablets to add to every liter of water to aid absorption at altitude.
Organize with dry bags. Use color-coded 5L to 10L dry bags to organize your gear inside your pack. This keeps your clothes dry during unexpected mountain storms and makes finding items in a tent easier.
