Base weight is the weight of everything in your pack except consumables (food, water, fuel). It is the constant weight you carry regardless of trip length. Ultralight backpackers target a base weight under 10 lbs (4.5 kg), while lightweight is under 15 lbs (6.8 kg). Reducing base weight improves comfort, speed, and joint health over long distances.
- Ultralight: base weight ≤ 10 lbs (4.5 kg)
- Lightweight: base weight ≤ 15 lbs (6.8 kg)
- Traditional: base weight > 15 lbs (6.8 kg)
- Average thru-hiker base weight: 12–18 lbs
- Every 5 lbs saved reduces knee and hip strain by 15–25%
