Regular travelers should always have mylar blankets on hand, especially when camping in any place with extreme seasonal weather or night temperatures. Made with waterproof and weatherproof foil and mylar, these emergency thermal blankets are the ultimate lifesavers and will keep you cozy and safe during your adventures. The mylar insert provides insulation, while the foil cover reflects heat back to your body or deflects heat from the sun. You can use these blankets to line a sleeping bag, for a temporary shelter, or even cover part of your RV to reduce heat transfer.  Stay comfortable and prepared by taking these with you on your next journey!
