What should the total pack weight be?

Aim for your base weight (everything except food and water) to be under 20 pounds. With food and water, your total pack weight should ideally stay below 35 pounds for high-altitude trekking.

Does altitude change how I pack?

Yes. The air is thinner and colder, so you need more layers than at lower elevations. Pack more fuel for melting snow into water and ensure your sleep system is rated at least 10 degrees colder than the expected nightly low.

How to Pack Your Backpack for High-Altitude Hiking

Pack your gear by keeping the heaviest items close to your spine and mid-back to maintain your center of gravity. Distribute weight evenly from side to side and keep your most-used items easily accessible to avoid constantly unpacking on the trail.

Layer the bottom. Place your sleeping bag and sleeping pad at the very bottom of the pack. These are light, bulky, and usually only needed once you reach camp, serving as a stable foundation for the rest of your gear.
Position heavy gear. Place heavy items like your bear canister, stove, fuel, and extra water supply directly against the middle-back panel of your pack. This keeps the weight close to your center of gravity, preventing the pack from pulling you backward.
Fill the gaps. Use your clothing, extra socks, and smaller loose gear to fill the empty spaces around your heavy items. This prevents your gear from shifting while you are navigating technical or uneven terrain.
Organize your lid and pockets. Store your essentials—headlamp, high-altitude sunscreen, lip balm, GPS, and light snacks—in the pack lid or hip-belt pockets. You should be able to access these without opening the main compartment.
Secure external items. If using trekking poles, strap them to the side compression straps when not in use. Ensure all external straps are tightened so nothing dangles and gets snagged on rocks or brush.
