ALPS Mountaineering  Fusion 40 Sleeping Bag

I've used this bag now for 3 years for bike packing, and so far it has held up without ripping. It's a lightweight bag intended for summer nights, since the bag is rated 45 degrees, this is a false rating that ALL sleeping bag makers use, you have to add 15 degrees to any sleeping bag to get closer to the actual lowest temperature you would be comfortable at (quilts are NOT like this though). I carry a blanket that can roll up real small and weighs next to nothing that I use just in case the weather gets below 60 or 55. The zipperless thing is a bit odd, not sure what the reasoning was behind this sort of engineering, not so sure if I like it, so I downrated it 1 star because of that odd design. There are not that many fasteners either so cooler air can enter between the fasteners, but like I said, it's a summer bag, and summer only. I do like that the top of the bag is down, and the rest is synthetic fill, the down top lays very light on my body which I prefer. I'm on a limb if I would recommend this to a friend, I said no in my comments only because I think most people would probably want a bag that closes with a zipper. But I am 72 inches long, with a narrow body width, and the bag does fit me quite comfortably without being even remotely tight anywhere, so I like that about the bag.

Bought this thinking it would be perfect for early spring/summer camping, with the top entry being great for hammock camping. After the first night, the seam at the head started ripping. By the end of the 4 day camp/paddle trip, I'd ripped two of the toggles completely off the quilt top and the down was coming out. All I did was roll over while sleeping. Great idea for a bag....quality sucks. Can't recommend this bag at all. Spend the money and opt for a more quality bag such as the REI brand, Marmot, or Nemo.
