Very lightweight and well made

Great for multi-day pack hiking in a temperate or warm environment. MUST have a decent pad with it and have an extra layer ready to go if the temperature drops into the 40's or lower (in my opinion). I'm 6'2" and 250 lbs. Fits nicely. It's not roomy, but adequate and easily covers everything if needed. I like the diagonal cross-body zipper design that allows the bag to be unzipped for more air in warmer weather.

Overall a decent bag

This is rated as a 3 season bag, but given the temp ratings I would rate it mostly a 2 season bag. I am 6ft and 155lbs, this had plenty of room for me to change positions and get comfy. The zipper is good though it did on occasion get caught when zipping. The rating could be increased by adding a quilt and a good quality sleeping mat but you will have to determine what works best for you. I tend to like to sleep warm and so far it has been great in the cooler evenings. I think overall as a stand alone bag it would be great for car camping, family camping, a weekend away during warmer seasons but this is not one I would pack for a backpacking trip. This is a great bag for the price if you want a basic sleeping bag then this is a perfect fit!

Comfortable

Soft but warm sleeping bag. It's stitched well, and will hold up well. It was reasonably priced and I am well pleased.
