The engine's answer

Best ultralight backpacking kit for one person on a weekend in winter nights near −12 °C, under €700

Why it wins, in numbers

The four items come to €645 of the €700 ceiling — €55 to spare — and weigh 2.94 kg together before food and water. They pack to 38 L of the 44 L the pack offers.

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 38 L, and €700 for all four; anything that falls short of these is flagged beside the item.
