Emergency foil blankets are pivotal in first aid and emergency scenarios. Recognised by NASA and endorsed by the British Standard Regulations (BS-8599), these blankets are specifically designed to reflect up to 90% of body heat. Their waterproof and windproof capabilities provide optimal protection, making them a prime addition to any first aid kit. Crafted from the advanced material, Kelvalite, which combines a polyester film with a vapourised metallic coating, these blankets ensure heat retention even in wet conditions, safeguarding the wearer against hypothermia. With the added benefit of being individually sealed in pocket-sized poly bags, they remain a compact and indispensable tool for emergency situations.
