5X Premium Foil Survival Blanket, Reflective & Thermal Safety, Emergency First Aid

You need how to use these as there are 2 sorts of reflective foil blanket[1] like this - lightweight, can tear[2] reinforced, strong, heavierIf you want a tough reflective layer to use in bivi-shelters, or under camp mats when sleeping on ice-fields or glaciers look elsewhere.This type needs to be used very carefully to keep a layer of warmth around you - often in combination with other layers. It tears if handled badly and can't easily be tied (hint, your sticking plasters can be useful here)If you are heading to the hills, do take time to research how you would keep an injured climber safe and warm BEFORE you head out. There are excellent web-pages and online videos that teach you this.My teaching is that you really need 2 blankets per person to make a real impact - which is why I buy these in multi-packs. In the UK, where rain is common, also look on Amazon for the much tougher "Bivi-Bags" that can double up as rucksack liners, as the two items are often needed in combination, are both inexpensive and relatively lightweight.

Cheap and what I wanted, very happy

Exactly as advertised

Very good, however quite thin so consider them disposable (I wouldn't imagine they'll refold that easily).

Well worth the money

great product

These arrived sooner than anticipated and are exactly what I was expecting

Foil blankets, like they say!
