Why it wins, in numbers

Rab Neutrino 400 is the sleeping bag the engine picked for this trip: €470 and 830 g, Comfort rating -2 °C, a 50% match on the questions asked. The kit around it comes to €885 of the €1,000 ceiling, leaving €115.

What the engine asked for: a sleeping bag rated to 1 °C or lower, a mat with an R-value of at least 2.5, a pack of at least 38 L, and €1,000 for all four; anything that falls short of these is flagged beside the item.
