#sleep
The Hanoi-Đà Nẵng night train sets its own rules
Four berths, a light that never turns off, and a bag you have to watch while asleep. Three constraints, three answers of very different bulk.
The silk sleeping bag liner deserves better than its reputation
A summer-camp object, a stated hundred and twenty grams, and a question you only ask yourself once you're lying down.
Eleven hours on a layover in Istanbul with an inflatable pillow
Eleven hours in a transit terminal, armrests welded to the frame, and an object everyone judges on a plane, exactly where it's useless.
Thirty-four degrees in the room, five fans
One single problem, sleep. Five objects that claim to solve it, four eliminated, and a selection constraint that isn't the one you'd expect.
