"Good summer alternative to sleeping bag"
Great versatility for summer or warm weather use. I was looking for a 40/50+ degree sleeping bag for summer use when I came across this. Since I have a thermarest air mattress and fitted sheet it was even a better option for me since I can use it as a comforter or a sleeping bag/system. Much better option for warm summer nights when car camping vs. overheating and overusing my down backpacking bag. Fit, quality and ease of use are consisten with high quality thermarest gear.
This is one of my favorite pieces of gear. I take it on every trip. With a Therm-A-Rest pad and one of their fitted sheets its a perfect summer set-up, but is great as a back up when it gets a bit colder than expected.
