It is warm, but not warm enough for below freezing

Bought this for my son, and he loves it. He was even able to get it back in the bag lol

Exactly what I was looking for. I like that you can take the lining out. It’s almost like having two sleeping bags in one. It’s light weight. I was able to get it back in the bag. I always seem to struggle with this. Hopefully it gets easier. Seems well made and zippers appear strong. The size is perfect.

Overall, this sleeping bag is very comfortable and very versatile. I love that you can customize it to match the conditions you are in. You can use it fully intact with the bag and the liner, or you can use each separately. The liner can also be used separately as a blanket if needed.
The zippers are good quality and move very freely. The sleeping bag also has a hood that can be cinched down around your head for colder weather. There is a pocket on the inside where you could keep a phone or maybe a small flashlight.
Complaints:
I do think this is a little overpriced at $99. Also, the storage bag is very small, making it extremely difficult to get the sleeping bag back in. It took me about 10 minutes of struggling with it to get finally back in the bag. I may end up using it without the bag and just using some straps to hold it together. It seems like whoever designed this must not have tried it for themselves, otherwise they would have come up with a better solution.
Conclusion:
I really like the versatility and comfort this sleeping bag offers, I just wish the it was easier to put away.

Kingcamp 3 in 1 sleeping bag
This is a very nice well built bag. Firstly, this is not for backpacking unless you want to carry a bag that weighs 3354g (118.3oz, 7.394lbs) and when tightly packed is 17 inches long and 10 inches in diameter.
It was tough to pull out of the compression sack it was packed in so tightly, it was as you can imagine equally tough to roll up and get back in the compression sack, something that will be a struggle to do in a small tent. I would like to see the bag a bit bigger. (Not that you would be rolling, instead you would be stuffing)
It is a nice design where you can remove the inner bag to use as a lighweight warm weather bag, or you can zip together for cold weather. I would like to have seen some interal baffles at the bottom corner where the side and bottom zip don't quite meet, I imagine that is a place where cold air could get it. Other than that this is a perfect bag.
Thank you for reading my review and looking at my photos of this product. I hope you found it helpful!
REVIEW PHILOSOPHY: I only review a product if it is something I am capable of critically evaluating through comparison, testing and use. This means I have experience of using similar items; or that I have equipment or tools that I can test it with; or that I have an upcoming need so I can actually use. I am as selective about getting an item to review as I would be about purchasing that same item, so yes, I expect it to be a good product. My reviews are NOT based on packaging or if it was delivered timely.
