What it's good for
Reflects your own heat
The aluminised lining sends body heat back rather than generating any — which is why it works in a bag but not spread flat.
Small enough to forget
Packs to roughly the size of a fist, so it lives in a glovebox or the lid pocket of a rucksack.
Visible on purpose
The bright orange is a signalling color as much as a design choice.
