The engine's answer

Best backpacking kit for one person on a weekend in frosty nights near −5 °C, under €400

Why it wins, in numbers

The four items come to €305 of the €400 ceiling — €95 to spare — and weigh 4.15 kg together before food and water. They pack to 40 L of the 50 L the pack offers.

What the engine asked for: a sleeping bag rated to −7 °C or lower, a mat with an R-value of at least 4.5, a pack of at least 40 L, and €400 for all four; anything that falls short of these is flagged beside the item.

The kit it belongs to

Four items chosen together, not four separate winners. Swapping one moves the others.
