  • Packs smaller than a one-litre bottle
  • Ideal for fast summer trips
  • Fragile — treat it as a consumable

Why it wins, in numbers

Therm-a-Rest NeoAir UberLite is the sleeping mat the engine picked for this trip: €220 and 250 g, R-value 2.3, a 50% match on the questions asked. The kit around it comes to €920 of the €1,000 ceiling, leaving €80.

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 29 L, and €1,000 for all four; anything that falls short of these is flagged beside the item.
