I used this product for a primitive camping/hiking experience in ocala national forest. The night started off warm but i did notice it was getting cold so I decided to check the weather noticed it was going to get down to 58°, so I chose to try this sleeping bag i bought for emergencies a kind of test run. Here's what i found this bag will keep in heat but also condensation and it easily ripped. Wind got right in and chilled the condensation In the bag. Woke me up multiple times throughout the night. Depending on the situation this is not a good bag you could freeze or get noooo sleep from the crinkling and/ or alert enemies. Conclusion very light weight, warm if your super still and not windy, not so durable.
