The engine's answer
Best ultralight backpacking kit for one person on a week in chilly nights around 3 °C, under €400
Why it wins, in numbers
The four items come to €375 of the €400 ceiling — €25 to spare — and weigh 3.18 kg together before food and water. They pack to 33 L of the 44 L the pack offers.
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 33 L, and €400 for all four; anything that falls short of these is flagged beside the item.
