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. Warmth is a "good enough" gate; the rest score on a sliding scale. Price is a lever you turn on when budget matters.

Sufficiency
Only needs to be good enough. Warmth works this way: clear your target and you're set, extra warmth adds no points.
Monotonic
More (or less) is always better. Lighter beats heavier and smaller packs beat bigger, so they score on a sliding scale.
Preference
Type, shape, and inflation are personal preference, never scored. They only filter the list.
