This was a gift for my husband as our other sleeping bag used for the boat needed replacing. I ordered this after spending quite some time looking for what I wanted in stores and on line. We use sleeping bags all year round on our boat, I am always cold he is hot. I love it! Easy to pack away, heavy, side zippers allow him to open bag without freezing me. I hope this will last 10+ years like the last one. Was concerned when I got the box as it was destroyed during delivery, but didn't seem to impact the bag at all.
