Review on Tuphen Sleeping Bags: All-Season Cold And Warm Weather Gear For Backpacking, Hiking, And Camping – Lightweight, Waterproof, And Perfect For Adults, Kids, Boys, And Girls – Indoor And Outdoor Use by Kevin Carr

Overall happy with the material/description of the weather condition recommendations. The bag kept my daughter warm tent camping during 31 degree weather. Keep in mind she was wearing layers and wool socks. However, I am very disappointed in the construction of the string to tighten the area around the head to keep the heat contained. She would not have had to wear several layers if this did not break on the first use.
