Why it wins, in numbers

Cumulus X-Lite 200 is the sleeping bag the engine picked for this trip: €290 and 450 g, Comfort rating 7 °C, a 52% match on the questions asked. The kit around it comes to €610 of the €700 ceiling, leaving €90.

What the engine asked for: a sleeping bag rated to −14 °C or lower, a mat with an R-value of at least 5.5, a pack of at least 39 L, and €700 for all four; anything that falls short of these is flagged beside the item.

Questions this trip raises

How much does the whole kit cost?
€610 for all four items, €90 under the €700 ceiling. Prices are indicative euro list prices; the shops set their own.
How much does it weigh?
3.78 kg base weight — tent, sleeping bag, mat and pack together, before food, water and clothes. The pack is rated to carry 16 kg comfortably.
Is Cumulus X-Lite 200 warm enough for −12 °C nights?
Its comfort rating is 7 °C. For nights near −12 °C the engine requires a rating of −14 °C or lower, which it misses — nothing under this budget did, so the engine flagged it rather than leave the slot empty.
