Pyramid emergency bags and blankets are constructed from a combined metal and polyester sheet that reflects and retains up to 90% of body heat (80% for the blanket alone). The non breathing substrate ensures no wind or moisture penetration. The gold blankets make for great sight recognition in snow or water, whilst the silver bag retains over 90% of body heat and is ideal for putting over a sleeping bag in cold, wet or snowy conditions.
