How much should my pack weigh for high altitude trekking?

Maximum 20% of your body weight, ideally 15-18%. Your cardiovascular system works much harder at elevation, so every pound counts. A 150-pound person should carry no more than 30 pounds total.

Why avoid down insulation at high altitude?

Down loses insulation when wet, and you sweat more at altitude due to increased breathing and exertion. Synthetic insulation maintains warmth when damp and dries faster. Save down for dry, cold conditions only.

Do I need special boots for high altitude trekking?

Yes. You need insulated, waterproof boots with aggressive tread. Regular hiking boots aren't warm enough and don't provide adequate traction on snow, ice, or loose scree common at altitude.

How do I pack for 40+ degree temperature swings?

Layer system is everything. Start cold in the morning, strip layers as you warm up, add them back for lunch stops and evening. Pack clothes you can put on without removing your pack.

How to pack for high altitude trekking

Pack in layers for extreme temperature swings, prioritize synthetic insulation over down, and bring altitude-specific gear like electrolyte supplements and a pulse oximeter. Your pack weight should stay under 20% of your body weight to avoid overexertion at elevation.

Choose your base layers. Pack 2-3 merino wool or synthetic base layer sets. Avoid cotton completely - it kills at altitude when wet. Bring one lightweight set for warm days and one midweight set for cold mornings and evenings.
Layer your insulation. Pack a synthetic insulation jacket (not down - down fails when wet from altitude sweats). Add a fleece or soft shell for adjustable warmth. You'll be putting layers on and off constantly as temperature swings 40+ degrees between morning and afternoon.
Waterproof everything critical. Bring a hardshell jacket and pants rated for serious weather. Pack all electronics, medications, and spare clothes in waterproof stuff sacks. Afternoon storms hit fast above 10,000 feet.
Pack altitude-specific gear. Bring electrolyte tablets (you dehydrate faster at altitude), a pulse oximeter to monitor oxygen saturation, and altitude sickness medication if prescribed. Pack lip balm with SPF 30+ and glacier glasses - UV exposure doubles every 1,000 feet of elevation.
Minimize pack weight ruthlessly. Weigh everything. Cut off clothing tags. Bring only essential electronics. Your cardiovascular system works 25% harder at 12,000 feet - every ounce matters. Target 15-18% of your body weight maximum.
Test your gear beforehand. Wear your boots for 20+ miles before departure. Test your sleeping system in cold conditions. Break in your pack with weighted training hikes. Gear failures at altitude can be deadly, not just inconvenient.
