Product as described. Reasonable size, cheap, each packed blanket easily fits in a pocket. A blanket makes a fast and simple outdoor shelter - waterproof in non-extreme conditions. Reflective on both sides so decent at retaining body heat. A good easy-to-carry extra insurance for general outdoor activities.
Note that the blankets are only reasonably robust - they can tear quite easily so really only suitable for single use. They don't have reinforced edges or holes for secure attachment - but are not sold or advertised for such 'more extreme' uses.
