Yes, there are cheaper ones available, but though the ones I have tried, nothing is better. It gives you that added temperature difference, getting the most out of your sleeping bag, even more useful when you have a slightly underspec'd season sleeping bag. It's very comfortable and makes sleeping a lot more comfortable. Also don't forget it's a great protector for your sleeping bag. Wash wise, I have had no problems....(I don't hand wash it) so I wouldn't worry about the maintenance of it either! The only "fault" if I'm scraping the barrel, would be yes I suppose it could be a little cheaper, but looking at its usage and comfort, I have easily had my money's worth out of it
