Heat Reflective Bed Sheet Underlay

Developed by NASA to help astronauts combat freezing conditions in space, heat-reflective technology helps the body adapt to extreme temperature fluctuations by preventing overheating and eliminating chills for optimal warmth. Incorporating these advanced principles, our heat-reflective under blankets with aluminium lining, stop heat escaping through your mattress, whilst soft foam underlay adds heat-insulating comfort for a super cost-effective way to stay warm during cold winter nights.
