Great And Lightweight!I bought this sleeping bag to take to the hospital when my wife gave birth. Sleeping on the couch with nothing but a hospital blanket was not going to cut it. This Dolomite easily fit in with all of our hospital gear, was easy to unpack and pack, and did a great job keeping me both comfortable and warm.

Good Choice for Larger Guys (Long Version)I am a big guy with very broad shoulders (6'4" - 240). I sleep on my side. I have hated every mummy bag I've tried, they just aren't big enough to be comfortable for large guys like me. This one fits, and is still light enough to take backpacking. Realistically, I would say mid-50s and above is where this bag is comfortable on its own, when it hits about 50 you will either want to be dressed warmly inside it or want something more. But realize that it can easily be extended into the shoulder seasons with an inexpensive fleece liner and/or a lightweight camping blanket. I combined this with the snugpak jungle blanket for some camping in Maine and it got down to mid-30s and I was perfectly comfortable. Since this thing isn't that heavy to begin with, adding more layers doesn't kill you on weight, and it gives you a lot of flexibility to adjust to the conditions. Although it does not come with one, it can be compressed into a small compression sack, but the instructions warn you not to store it compressed for any length of time. It is an excellent value.

Great productI bought this bag for lower elevation Sierra summers. It works well for California winters (not in the Sierras!), so it should be fine for summer. It's roomy and comfortable. Good choice.

Great bag!I picked up this sleeping bag at a great price to take with me on backpacking trips. It's light at 2+ lbs and warm enough for 3 seasons (with adequate layers in chilly mountain temps). On warmer nights I sleep on top of it giving my sleeping pad extra padding. It's not as light/warm as down bags, but it does the trick. And it being a fraction of the price as a down bag, it's also pocket friendly.
