User Review: Therm-a-Rest BaseCamp
Source: bought it new
Price Paid: $75
The classics are classic for a reason. Durable, insulating, and comfortable. Reasonably priced.
This is a reasonably weighted pad that has withstood the test of time and teenagers. I had one when I was a teenager, and now I've moved on. It worked OK for backpacking and car camping, but wasn't exceptionally light or exceptionally comfortable.
Now Thermarest has both options (Neo Air and Dreamtime, respectively) and I will let my children and less-reliable friends use these. The biggest advantage is that these will last a long time and not develop leaks. They can take a fair amount of abuse, and self-inflate. I have had mine for more than ten years.
