I used a lightweight fleece liner in upper 30s F--with cotton clothes single layered--and was chilly but never shivered. It was very comfortable in upper 40s to lower 50s. I slept with the bag itself unzipped and the liner zipped. Well worth the money. Sleep is one of the critical things I never skimp on while living out of a tent. Had a bit of issue with the zipper catching but not to where it would be problematic long term. It has flaps that cover the neck area to trap in heat and packs down reasonably small. It does not weigh very much at all.

size: 800g Down Filling; color: Orange. Great for backpacking as it can stuff into a small sack and is very light. Keeps me warm in the lower 50s...so far. Have not yet tested lower temps. Love the neck wrap that helps seal in heat. Comes with a mesh bag, perfect for long term storage.

size: 1000g Down Filling; color: Orange. Very warm. Good light weight for the price point and very comfortable. We'll see how durable it is after a few seasons.

size: 1500g Down Filling; color: Orange. I was heading to Death Valley in February with my off road club. We would be camping at about 4,000 feet and the temperature would be around 30 degrees. For the price I opted for the 1500 bag. I received it two days before the trip and was hopeful that it would work. The nights got down to 26 degrees and most of my group complained about the cold in the morning. I wore socks, shorts, shirt and a beanie cap and was as warm as could be. I think the quality of the bag is very good and time will tell. For the cost I would highly recommend this bag and look forward to my next cold camping trip.

size: 1000g Down Filling; color: Orange. Wonderful, cozy, plenty of leg room, and light weight. I LOVE this bag! Most are too restrictive. This one is terrific. I need to be able to shift around and move my legs and feet. This one does that, while being soft, cozy, and totally comfortable. I am also one of those folks who have a hard time smooshing these things back into their bags. I don't want to spend a half HOUR trying to get the thing back into a tiny bag. THIS one provides a nice good-sized mesh bag that one gets the thing back into VERY EASILY. Thank Heavens!

size: 300g Down Filling; color: Orange. I love this bag. Very light and compact yet quite warm considering the weight and profile. Well made of quality material and very cool looking at the same time. This bag will compress to about the size of a large coffee can which is impressive considering how warm it is. I used it at 40 degrees with only socks, shorts and a t-shirt and was very comfortable all night. I would recommend a sleeping pad as this is an ultralight bag and out offers little to no padding. A great buy for the price, there are considerably more expensive options but I'm glad I opted for this. I plan on getting more for Christmas gifts.

size: 1000g Down Filling; color: Orange. I'm not a sleeping bag connoisseur, but I used this for 5 nights in the Andean mountains of Peru and I was VERY comfortable! One night it got into the 20s; I was perfectly toasty with this and my bag liner from Sea to Summit. It was pretty packable; I brought it in a checked bag, and it was much smaller than the bag my tour company provided and much warmer. I love how the hood can seal around your head, and the little collar on the inside to keep out cold air. The zipper worked perfectly, and I was able to wash this successfully at home. I will be using this bag again next month out in California. The night temps will be in the 40s and 50s and I plan to use it more like a blanket.
