Temperature & provenance
The maker publishes a single self-assigned rating (no EN/ISO lab test). Maker ratings follow the survival-oriented "limit" convention and run optimistic, so for scoring we standardize it to a comfort-equivalent of 36°F (a documented, uniform adjustment). This is how a lab-verified bag out-ranks an optimistic marketing number.

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 (a standardized comfort rating) is a "good enough" gate; weight and packed size score on a sliding scale. Price and fill power are levers presets turn on.
Customize on the full comparison →- Sufficiency
- Only needs to be good enough. Warmth works this way: clear your target temperature 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
- Style, fill, and shape are personal preference, never scored. They only filter the list.
