Review on Stay Warm And Help Others: DIBBATU Emergency Survival Sleeping Bag For Camping, Hiking & Outdoors by Curtis Castillo

Bought these as emergency supplies for a very challenging hike. Fortunately they were never needed. I really like the sack concept over the standard emergency blanket. This would keep the wind out and definitely keep you warmer. But it does come with a weight penalty. My scale shows each bag at 117g (4.1 oz) which is not light. But I do think they would work well if ever needed.
