Why it wins, in numbers

Alpkit Cloud Cover is the sleeping bag the engine picked for this trip: €180 and 600 g, Comfort rating 2 °C, a 85% match on the questions asked. The kit around it comes to €400 of the €400 ceiling, leaving €0.

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 37 L, and €400 for all four; anything that falls short of these is flagged beside the item.
