It weighs about as much as a chocolate bar, lives in the lid of a rucksack for years, and on the one night it is needed it keeps a body heat in when everything else has gone wrong.\u003c\/p\u003e\u003ch3\u003eWhat the manufacturer states\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 215 × 90 cm, envelope shape\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e about 110 g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePacked:\u003c\/strong\u003e 12 × 18 × 2 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e PE with an aluminised reflective layer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWaterproof\u003c\/strong\u003e and windproof; the reflective side is visible in low light\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat it is, and what it is not\u003c\/h3\u003e\u003cp\u003eThis is a survival item, not a sleeping bag. It has no insulation of its own — it works by reflecting your own body heat back and stopping wind and rain from stripping it away. You will not sleep well in one. You will, however, be considerably warmer than you would be without it.\u003c\/p\u003e\u003cp\u003eSlit down one side it also works as a groundsheet or, with a length of cord, as a lean-to shelter. Mountain Rescue teams in the UK have been telling walkers to carry one for decades, and it is the cheapest piece of safety kit in this shop.\u003c\/p\u003e\u003cp\u003eCarry one per person.
