Keeping warm

I took it out in my back yard to test it. It was 8 degrees felt like -8. I had on a jacket and sweat pants. I laid in 8” of snow for a half hour. I didn’t have gloves on and my hands never got cold as I held the bag closed. They are generally very sensitive to the cold. This product works as advertised. I highly recommend it. Read more

Great for vehicle or home

We bought these to keep in our vehicle. They are compact, and when you unfold the sleeping bag, it is very big. They will definitely do what we need it to do in the event of an emergency. They don't take up any room at all. Very awesome. Definitely recommend. ❤️‍🔥😁😎 Read more
