How scoring works
The same GearScore engine the comparison pages use. This is the default weighting; open the full comparison to re-weight it around your trip.
GearScore blends published specs into one 0 to 100 number. Capacity is a "good enough" gate; weight, rated load, and fabric denier score on a sliding scale. Price is a lever presets turn on.
Customize on the full comparison →- Sufficiency
- Only needs to be good enough. Capacity works this way: enough volume to carry your trip and the pack is set, extra liters add no points.
- Monotonic
- More (or less) is always better. Lighter beats heavier, a higher rated load beats a lower one, and tougher fabric beats thinner, so they score on a sliding scale.
- Preference
- Type and frame are personal preference, never scored. They only filter the list.
