Qué saco elijo: a sleeping-bag comparator

Field notes

The comparator treats sleeping-bag specifications as a data-cleaning problem rather than repeating product labels. It converts fill-power measurements to a common European basis, foregrounds comfort temperature over the more dramatic extreme rating, and tracks whether a product has an ISO 23537 test. The visible catalogue has 18 entries, including 11 down and 7 synthetic bags, while reader-submitted additions are reviewed before publication.
