Why it wins, in numbers

Deuter Orbit +5° SQ is the sleeping bag the engine picked for this trip: €90 and 1.50 kg, Comfort rating 5 °C, a 95% match on the questions asked. The kit around it comes to €680 of the €700 ceiling, leaving €20.

What the engine asked for: a sleeping bag rated to 6 °C or lower, a mat with an R-value of at least 1.5, a pack of at least 35 L, and €700 for all four; anything that falls short of these is flagged beside the item.

Comfort ratings and R-values are comparable across brands but describe a standardised sleeper on standardised ground — neither is a promise about you on a particular night.
