Very nice
For the money you get a well made, spacious sleeping bag. I was surprised and pleased to discover how spacious it is. In my case I bought this and a dolomite 20 degree to zip them together to sleep with the sig other (which works great by the way). That way the depending on the weather, you have one side that is better for cold weather and flip it over when it gets warmer in the morning or what have you. Good sleeping bag on its own though too. Not sure if it would be good down to 40 degrees like it says as I have not tested it yet, but it seems pretty light so it will be my late spring/ summer/ early fall bag so that is ok with me.

Awesome Sleeping Bag
This is a great sleeping bag, very light weight, nice color and just enough room to get comfortable. I purchased two long bags and zip them together for my 50lbs vizsla and I. Very warm, and excellent quality. I was extremely impressed how fast my order was processed and shipped, I ordered online on Weds, and had my bags by Friday!

Lightweight and easy to roll. Good bag for warm weather camping
I bought this bag for my teen age son to take to overnight camp. It rarely goes below 60 at night and often is much warmer where he goes to camp, so this light weight bag that unzips fully seemed ideal. We wanted synthetic so that if it rains, the bag will dry out quickly.

North Face 40 degree bag
I bought this for warmer weather as my down bag was much to hot for summer camping . This bag is good for car camping,to big for backpacking. It is lightweight, nice color, and very roomy ! In Flagstaff AZ night time in the 50's ...I was a little cold , had to put another blanket over me .
