Mart Cobra Mylar Emergency Blankets (4-Pack)
A four-pack of compact aluminized mylar emergency blankets (about 52 × 82 inches each when unfolded), individually pouch-packed for a glove box, go-bag, or first-aid kit. They reflect body heat and block wind and splash — useful if you're stuck roadside in a freeze, not a substitute for real shelter, dry clothes, or getting to a warm place.
