Review on Stay Warm And Safe With DIBBATU Emergency Survival Sleeping Bag: Waterproof And Lightweight For Camping And Outdoor Adventure, And Help Homeless People by Kevin Hauck

Did an experiment with my infrared thermometer. It was 51 degrees outside and very windy. I laid down a blanket in my driveway and placed the opening so wind would not blow into bag. I was cold upon entering bag. Thermometer showed 61 degrees inside. About 5-10 minutes later it was about 71 degrees. At first I had my whole body inside, but the plastic became damp from breathing inside. My face didn't feel cold in the wind with it outside the bag as the inside was warm. I only had a short-sleeved shirt on. I was comfortable enough, but would recommend a long-sleeved shirt to avoid touching the colder material with the bare skin when repositioning.
